Important Safety Instructions The word “Caution” is the lowest of the three signal words (Caution, Warning and Danger), with “Danger” being the highest. Therefore, whenever the word “Caution” is used, it may be replaced with either of the higher rated signal words: “Warning” or “Danger.
A/C Power Warning Users should exercise extreme care when working with electricity. Additional care should be used when working with electricity outdoors in inclement weather. When working outdoors or near water, always connect the system into a ground-fault interrupting circuit. There are no user-serviceable parts inside the Tempest BaseStation, Transceiver, or BeltStation. Opening the case may expose dangerous electrical components, and will void the warranty.
Battery Safety Battery Transportation Rechargeable lithium batteries are subject to special regulation by U.S. and International laws, particularly regarding transportation on passenger aircraft. However, individual batteries installed in consumer electronics are not restricted, provided there are only the correct numbers and types of batteries as may be needed to operate the electronic equipment.
Maintenance and Care Cleaning Generally, the Tempest Wireless hardware should be cleaned only with a dry cloth. A soft cloth with rubbing alcohol may be used to wipe the units if needed. Never spray solvents or chemicals onto the units. Because of Tempest’s weather resistant design, it is not highly susceptible to dust or airborne contaminants. However, all electronic devices can be susceptible to particulate contamination.

Theory of Operation The above illustrations show the theory of operation for both the 4-channel (dual antenna) and 2-channel (single antenna) models of Tempest. The 2-channel model lacks some of the diversity characteristics found in the 4-channel model. Tempest uses Frequency Hopping Spread Spectrum (FHSS), Time Division Multiple Access (TDMA), and 2xTX technology.
With 2xTX technology, each audio packet is transmitted twice, each on one of two consecutive hops. The loss of one packet transmission in a harsh RF environment is common. However, because of the quasi-orthogonal frequency relationship of the consecutive redundant packet transmission, the potential for loss of any single audio packet (2 consecutive data packet transmissions) is dramatically reduced. In addition, each packet transmission is sent out from different antennas.

Accessory Items You May Require Headsets A Headset is required for each user (XLR-4F connectors). Headsets may use Electret or Dynamic microphones. Most major brand headsets that have the correct XLR-4F connector should be compatible, requiring nothing more than a simple Mic Gain adjustment. DC Power Input Cable To power the Tempest BaseStation via DC power (Battery) instead of AC power, you will need to provide a DC Power input Cable.
BaseStation Overview Front Panel Left 1- Local Headset Connector The 4-PIN XLR male headset connector is compatible with most Dynamic or Electret headsets that have 4-PIN XLR female connectors. This headset connector allows a user to communicate on any one of the two intercom channels. Controls for this connector are located to the immediate right. The mic gain for the Local Headset can be adjusted from the “Set Mic Gain” menu, under the “BaseStation Settings.
7- Volume Control The multipurpose Volume control operates differently depending on the mode of the BaseStation. In Operational Mode, turning the Volume control adjusts the volume of the local headset. Turning the Volume control clockwise increases the audio level, while turning the control counter-clockwise decreases the level. Press the Volume control to select the intercom channel to be monitored at the local headset connector.
Front Panel Right The Front Panel Right controls 1 – 7, will normally be used together to configure the Tempest BaseStation for 2-Wire or 4-Wire operation. 1- 2-Wire Intercom Type Slide Switch A&B The 2-Wire Intercom Type slide switch configure the BaseStation for the type of intercom that will be connected to the corresponding 2-Wire connectors on the rear panel of the BaseStation. Clear-Com, RTS, or BAL (AudioCom) can be selected. This switch only affects 2-Wire operation and not 4-Wire operation.
4- 2-Wire/4-Wire Select (SEL) Button The 2-Wire/4-Wire Select (SEL) button sets the wired intercom mode for each of the two intercom channels. When a channel is selected with the CHAN SEL button, pressing the 2-Wire/4-Wire Select (SEL) button changes the selected intercom mode between 2-Wire, 4-Wire, or no connection. 5- 2-Wire/4-Wire LEDs The four 2-Wire/4-Wire LEDs indicate the currently selected intercom mode for each of the two intercom channels.
Rear Panel Left 1- AC Power Input Connector The IEC AC Power Input Connector accepts the AC power cord. Use this connector with the supplied AC power cord to power the Tempest BaseStation from AC power between 85 and 260 VAC at 50 – 60 Hertz. The BaseStation will draw approximately 15 Watts (125mA at 120VAC, 65mA at 230VAC). 2- DC Power Input Connector The DC Power Input Connector accepts a Switchcraft S760 2.1mm x 5.5mm power plug wired as center positive.
Rear Panel Right 1- SA (Stage Announce) Connector The SA connector is used to output BeltStation audio to a dedicated audio output. The SA Connector is an XLR-3M connector and accepts a standard XLR-3F. The SA Connector is balanced and transformer isolated. Nominal line level is -12 to +8 dBu. The SA Connector output level can be adjusted under the Wired Intercom Settings menu. 2- Aux IN Connector The Auxiliary IN Connector is used to supply program or other audio sources to the Tempest BaseStation.
6- Local Area Network (LAN) RJ-45 Connector The Local Area Network (LAN) RJ-45 Connector is used to connect the Tempest BaseStation to a user supplied PC running Tempest Desktop Configuration (T-Desk) software. The user can then monitor and/or adjust BaseStation and BeltStation settings via the PC interface. This connection can be made directly or through a Local Area Network (LAN). See the separate T-Desk User Manual for more information.
BeltStation Overview 1- Volume- CH A and CH B In Operational Mode, turning the Volume control adjusts the volume of the audio. Volume indicators appear on the display during adjustment and are expressed in Decibels (dB). The Volume control has an option to be set to “Volume Press” where it requires a “press and turn” to adjust the volume level. The “Volume Press” option can be adjusted under the “Set Controls” section of the BeltStation menu. Pressing the Volume control in “Dual-listen” mode does nothing.
6- CALL Button The CALL Button sends a 2-Wire compatible call signal to any wireless BeltStation and any hardwired intercom device on the intercom channel. The Call signal will be routed to intercom channels indicated by the user’s active Talk button(s). 1- Rubberized Access Cover The Rubberized Access Cover helps prevent dust, dirt and liquid from entering the BeltStation through the USB or the BeltStation pairing connector. Keep this cover securely closed at all times to ensure the best possible seal.
Talk Button A and B There are two TALK buttons on each BeltStation, one for channel A and the other for channel B. The Talk button enables the microphone signal for the assigned intercom channels. Tempest uses an intelligent latching method for TALK buttons. Pressing the TALK button momentarily will cause the TALK button to latch. Pressing and holding the TALK button will cause the button to act as a momentary switch. Talk tones can be enabled or disabled per BeltStation.
Bottom view of the transceiver Transceiver Controls 1- RX LED The RX LED illuminates when data is being received by the Remote Transceiver. This LED will remain illuminated during normal system operation. 2- TX LED The TX LED illuminates when data is being sent from the Remote Transceiver. This LED will remain illuminated during normal system operation. 3- SYNC LED The Sync LED illuminates when the Transceiver Sync signal is present. This LED will remain illuminated during normal system operation.
BaseStation Setup Steps to Setup the BaseStation • • • • Choose a location for the BaseStation Choose an antenna location and configuration Maximize performance Configure operation features » Set Frequency Band » Set Network Number and Lockout Key » Name each BaseStation and BeltStation (optional, but encouraged) » Set Static or Dynamic Display Configure optional features • Choose a Location A Tempest BaseStation mounted in an equipment rack with optional cables and mounting hardware.
Power Connections The Tempest BaseStation can be powered from AC or DC power. The front panel ON/OFF switch controls AC and DC power coming into the BaseStation. If AC and DC are both connected, the DC will act as a power supply backup in the event AC power is interrupted. AC Power Connection » Always connect the power cord to the Tempest BaseStation before connecting to the outlet. » Only use approved IEC AC power cords. » Only use AC power from 85 to 260 VAC at 50 – 60 Hz.
Antenna Location 24” Proper antenna location is essential for optimum system performance and maximum range. Antenna positioning is important with all RF systems and in all applications. Locate the Tempest BaseStation antenna as high as possible for your application to maximize line-of-sight RF operation. Positioning the antenna higher than head level is the minimum acceptable height for most applications. Maintaining line of sight between the BaseStation antenna and the BeltStation(s) is ideal.
Antenna Configurations Option 1 Install the BaseStation in the center of the area of communication, with antenna installed on the back of the BaseStation, having a clear line of sight in all directions. When attaching the supplied ½ Wave Omni-directional Whip antenna directly to the back of the BaseStation, always ensure that the antenna is firmly seated, is not cross threaded, and is located away from any metal obstructions.
To remotely locate antenna always use high quality, low loss, 50 ohm RF cable terminated with an RP-TNC connector for the BaseStation side connection and the appropriate antenna mating connector on the other end. LMR-195 (or equivalent) coaxial cables can satisfactorily be used in lengths up to 10 feet. LMR-400 coaxial cables (or equivalent) can be used at lengths up to 25 feet. Longer RF coaxial cable runs are not recommended due to signal attenuation in the cable.
Remote Transceiver Setup the Transceiver • Choose a BaseStation location. • Choose a Transceiver location. • Choose an antenna configuration. • Install CAT-5 cable and connect to the BaseStation and Transceiver. • Confirm operation by observing the Transceiver LEDs. The Tempest Remote Transceiver is an optional accessory that allows antennas to be located up to 1,500 feet away from the BaseStation without the RF signal loss that is associated with using long runs of coaxial cable.
Maximizing System Performance and Operational Range Radio waves (especially those at 2.4GHz) can be significantly affected by walls, windows, or other physical barriers. Concrete or metal walls can be of particular concern. Some tinted windows are also significant barriers to RF. Always position antennas to minimize interference from all barriers. A human body can be a barrier to the radio signal, especially when operating near the limit of the signal’s range.
Configure the BaseStation BaseStation settings can be configured in two ways: from the BaseStation menu or with the computer interface called “T-Desk” via a LAN connection. While many functions are available through both methods, certain features may only be available through the BaseStation. Using the Front Panel Controls The Tempest BaseStation can be configured depending on user preferences and the tasks to be accomplished.
Adjust Sidetone To demonstrate the use of the controls, this details instructions to adjust the “Sidetone” for the front panel headset connector: 1. Press MENU to enter Menu Mode 2. Rotate the Volume knob and scroll to “BaseStation Settings” on the display 3. Press ENT 4. Scroll to “Sidetone” and press ENT (or the Volume knob) to select Sidetone value is expressed in Decibels (dB). You will see a level indicator with a numeric value between -30 dB to -6 dB.
Selecting a Frequency Band The Tempest 2.4GHz wireless system is approved for license free use in most countries. However, due to differences in radio spectrum regulations, some countries require that 2.4GHz equipment limit or adjust its RF spectrum operation. Always determine if there are country specific frequency restrictions that apply and select the required frequency band as described below.
Network Number and Lockout Key The Network Number determines the RF frequency hopping pattern for the BaseStation and its corresponding BeltStations. This is a key operational parameter and is represented by a number between 0 and 42. When using multiple collocated Tempest BaseStations, it is imperative that Network Numbers are properly coordinated. BaseStations that are synchronized together using the ZSync technology must utilize the same Network Number Group for optimal performance to be acheived.
Adjusting Network Number and Lockout Key The Network Number and Lockout Key settings can be adjusted from the BaseStation, under the “Radio Configuration” section of the Tech Menu. Any adjustment to the Network Number and/or Lockout Key will require corresponding BeltStations to be re-paired with updated BaseStation. • Press MENU and select “BaseStation Settings.” • Using the Volume control, scroll to and select “Tech Menu.” Proceed through warning. • Select “Radio Configuration,” then “Network Number.
Set Display Mode to Static or Dynamic The Static or Dynamic selection only affects the order that the BaseStation LCD Operational screen displays BeltStation information. “Static” will be the preferred choice for users who want to ensure that a BeltStation that is logged in will always appear in the same location (slot) on the BaseStation display and are using only one BaseStation. Dynamic is the default setting.
BaseStation Headset Connection and Controls The BaseStation headset connection is a functional user communication point, and may also be used for setup and troubleshooting. The Front Panel Headset can communicate on any one of the two intercom channels. Controls for this headset are located just to the right of the connector, and in the menu on the BaseStation Settings screen. The front panel headset connector is a 4-PIN XLR male. A compatible headset must be provided by the user.
Front Panel Lock The Front Panel Lock function is intended to minimize the probability of unintentional adjustments to the system. Press MENU, select “BaseStation Settings,” scroll and select “Front Panel Lock,” press 1 or ENT to select Lock. Press MENU to exit to the main Operational screen. The buttons and knobs on the front of the BaseStation will not function until unlocked, except for the power switch which will power the unit OFF. When the BaseStation is powered ON, it is always unlocked.
GPO Relay Contacts Tempest Wireless provides six General Purpose Output (GPO) contact closures. These GPO contact closures can be used for interfacing with other external devices. The Stage Announce (SA) Relay and the five other GPO Relays, enough for each BeltStation to control one, are available through the DA-15 Relay Connector on the back of the Tempest BaseStation. These relays can only be triggered from the wireless BeltStations.
Auxiliary Output Audio from the Auxiliary OUT Connector can be assigned from any combination of the two intercom channels with Volume control at the “Aux Out Assignment/Levels” menu. Audio from the Auxillary OUT connector comes only from the wireless users and no audio from the hardwired intercom channels is routed to Auxillary OUT.
BaseStation Menu 40 Tempest®2400 2-Channel Wireless Intercom System
BeltStation Setup The BeltStation can be configured in three ways. It can be configured by the BeltStation menu, wirelessly by the BaseStation menu, or using the PC interface called T-Desk. While many functions are available through all three methods, certain features are only available through the BeltStation. See T-Desk manual for details on configuring by PC.
BeltStation Setup Steps to Setup the BeltStations • Install the battery. • “Pair” BeltStations to the BaseStation. • Adjust slot settings as needed. • Connect a headset. • Adjust Mic Gain. • Adjust Sidetone. • Configure optional features: » Name the BeltStation. » Disable unused functions, channels, and buttons. » Select/disable relay options as needed. » Adjust personal preferences.
Charging the Lithium-Polymer Battery With the Lithium-Polymer batteries installed in the battery compartment, plug the AC end of the supplied 5VDC Charger/Power Supply into a standard AC wall outlet. Open the rubberized access cover on the side of the BeltStation and plug the USB end of the Charger/Power Supply into the USB connector. The Lithium-Polymer batteries will take approximately 2¾ hours to charge from completely empty to completely full. This time is the same with the BeltStation turned ON or OFF.
Pairing with a BaseStation Pair BeltStation to BaseStation: Confirm that the BaseStation is powered ON and in Operational Mode (not in Menu Mode) and that the BeltStation is powered OFF. Confirm that the BaseStation’s Network Number and Lockout Key are adjusted as needed. See the section on Set Network Number and Lockout Key. Plug one end of the pairing cable into the BaseStation and the other end into the BeltStation. The pairing cable is a standard 3.5mm (1/8 in.) male to male stereo patch cord.
Adjusting so that each BeltStation always appears in the same position of the BaseStation display is a two step process: 1. Advance to the BaseStation’s “Display Slot Assignment” section of the “Tech Menu” and select Static. 2. In each BeltStation, advance to the “Base Slot” section of the “Tech Menu” and adjust each BeltStation to a different slot (1 – 5).
Call Function There are two call methods available in Tempest. The first uses the CALL button to send call signals to any BeltStation or hardwired user on the active channel. The second method is referred to as “Call On Talk” and uses the BeltStation TALK button to initiate a call signal. However, the “Call On Talk” feature works independently from all other BaseStation call settings and can be used to send call signals through intercom channels to attached radios or matrix.
Set Mic Gain Set the Mic Gain properly to ensure the best audio quality. To set the Mic Gain for the BeltStation Headset: 1. Press MENU to enter Menu Mode. From the Main Menu, select “Set Controls,” then “Mic Gain.” 2. While at the Mic Gain screen, talk into the headset microphone at a louder than normal level and adjust the Volume control until the PEAK LEDs just start to light at the loudest parts of the audio. Press ENT to accept the changes.
Seamless Roaming - BeltStation Configuration Installations with multiple BaseStation coverage zones often require users to move from one work zone to another throughout the day. Unlike iSe lect Roaming, Seamless Roaming allows users to roam freely from one zone to another without any manual adjustment on their part. The BeltStation will decide when it is time to change from one coverage zone to another.
BeltStation Menu 49 Tempest®2400 2-Channel Wireless Intercom System
Wired Intercom Interface to the BaseStation Each of Tempest’s twohardwired intercom channels can interface with a 4-Wire matrix intercom or a 2-Wire party-line intercom. Tempest supports a 4-Wire intercom interface to most major digital matrix intercom systems and other intercom 4-Wire devices. Tempest also interfaces with 2-Wire intercom systems including Clear-Com, RTS, and AudioCom (BAL) systems, as well as compatible brands.
Controls The 2-Wire Intercom Type Select Switch determines the type of 2-Wire intercom that may be connected to the corresponding 2-Wire connectors on the rear panel of the BaseStation. ClearCom, RTS, or BAL (AudioCom) can be selected. These switches only affect 2-Wire operation and do not control 4-Wire operation. The CHAN A&B switch selects the 2-Wire system type for both the A and the B intercom channels.
4-Wire (Matrix) Intercom Interface 4-Wire intercom systems use two pairs of wires to carry one full duplex channel of intercom audio - one pair for send and the second pair for receive. In addition to intercom audio, most systems have separate data lines that carry system data from the matrix to the remote devices. The Tempest 4-Wire connection is an audio-only interface to 4-Wire systems. Data can be present on the input cable but no data is utilized in the Tempest BaseStation.
2-Wire (Party-Line) Interface 2-Wire party-line intercom systems carry one or two (depending on the system type) channels of full duplex intercom audio, plus system power and other information on a single XLR-3M cable (2 wires and a ground). Each 2-Wire intercom type has a different wiring scheme and unique line characteristics. It is imperative to have the rear panel connections and the front panel settings adjusted correctly for audio to pass correctly between the systems.
Auto-Null Explained In 2-Wire intercom systems, inefficiencies in the hybrid circuitries that combine or separate the send and receive audio signals onto the same pair of wires inherently cause echo. Within analog systems the echo is not noticeable, but when connected to an extremely sensitive digital system, the echo becomes more problematic.
Manual Null Generally, Auto-Null will adequately control the inherent echo caused by the 2-wire hybrid circuitry. However, “Manual Null” is available if there is residual echo. If echo persists after testing for at least 30 seconds: 1. Turn OFF all TALK buttons on wireless and wired equipment. Since Tempest analyzes a tone to adjust the Null characteristics, any sounds entering through the wired or wireless systems will interfere with the nulling process. 2.
2-Wire Wiring Schemes Wiring schemes vary, and it is important to ensure that the cables are wired correctly for proper system operation. When Tempest is configured for a particular manufacturer’s system, Tempest routes the signal to internal circuitry that conforms to the requirements of that system. The 3-pin XLR connectors on the back of the Tempest BaseStation can have very different characteristics depending on the setting of the slide switch, as can be seen in the table below.
Modes of Operation Tempest Wireless BaseStations offer 3 modes of operation: Normal, Shared, and Split Mode. The mode of operation can be set by going into menu mode on the BaseStation. Press MENU and select “Mode Settings,” then “Operational Mode.” Note: In addition to the BaseStation, the BeltStations must be set into “Shared” mode to use with either Shared or Split modes of operation. Normal Mode In Normal mode, users can have up to 5 BeltStations (per BaseStation).
Split Mode In Split mode, users are operating in a combination of Normal and Shared mode. This mode offers the use of 4 BeltStations (per BaseStation) that utilize the standard anytime talk back capability and allows an unlimited number of “shared” BeltStations to listen and talk on the final slot. In this mode, shared BeltStations have no control over which channel they operate on. The channel is designated at the BaseStation.
Connecting Multiple BaseStations Tempest BaseStations may be used together to form large wireless systems, and may include external wired intercom systems. Intercom audio for any or all channels can be linked across multiple BaseStations. Audio from one BaseStation can be passed via a 2-Wire connection to another BaseStation, if they are to share a single channel of audio. Through this method, many complex combinations of intercom channels can be achieved.
Steps to Configure a Multiple BaseStation System • Locate and configure antennas to minimize RF interference. • Make Accu-Sync or ZSync connections. • Make 2-Wire Connections. • Configure for the appropriate 2-Wire connections. • Null each BaseStation. • Adjust IN/OUT levels if necessary. Audio Connections for Multiple BaseStations When using multiple Tempest BaseStations, it is often desirable to share the same communication channels across some or all BaseStations.
When an external 2-Wire hardwired intercom system IS present: Set the 2-Wire Intercom Type Select Switch to the proper type and select 2-Wire mode. Connect the hardwired intercom to the BaseStation. In this configuration, each connected Tempest BaseStation intercom channel will receive power and termination from the wired intercom system. The Tempest BaseStation functions as an additional wired beltpack from the perspective of the connected 2-Wire system.
Accu-Sync Three BaseStations Accu-Synced Accu-Sync provides a common timing signal between connected BaseStations. This signal ensures that transmission cycles for all Accu-Synced BaseStations occur simultaneously. This synchronized transmission eliminates the negative RF effect called desensing. See the following section, “Special RF Considerations for Multiple BaseStations,” for more information on connecting multiple BaseStations.
ZSync Technology Zero Sync (ZSync) technology has been developed to enable Tempest’s Seamless Roaming feature as well as greatly enhance the performance of non-roaming multi-BaseStation Tempest installations. The ZSync technology provides a more sophisticated form of BaseStation synchronization over the older Accu-Sync technology. To utilize ZSync technology either a Zero Sync Dongle or a Parallel Zero Sync Generator is necessary to act as the source of the ZSync signal. These devices are sold separately.
Parallel Zero Sync Generator The Tempest Parallel Zero Sync Generator (PSG) provides a precise, zero reference synchronization signal to each connected Tempest 2.4GHz BaseStation. This signal aligns the hopping patterns and transmit/receive times of all connected BaseStations to produce the best possible multibase, collocated RF performance. Parallel Sync Generator (Single Zone) A single Tempest Parallel Zero Sync Generator supports up to 12 Tempest 2.
Master Mode Master Mode is a Tempest BaseStation function that allows multiple BaseStations to share audio without the presence of an external hardwired intercom system power supply. Master Mode provides the necessary system termination to the 2-Wire hybrid circuitry in each of the Tempest BaseStations, so that common audio transfer can take place. Each BaseStation in a linked system provides its own power for audio. Either a single channel or both channels can be linked.
Special RF Considerations with Multiple BaseStations Whenever multiple Tempest BaseStations are operated together in close proximity, special consideration must be taken to ensure proper system operation and maximize operational range. See the Antenna Location section of this manual for more information on antenna placement. See the Antenna Configuration section of this manual for details about recommended cable type and other important information about connecting your antennas to your Tempest BaseStation.
Maximum Number of Collocated Systems Factors that affect the maximum number of systems that may be collocated in any given location include: • The existence and extent of harmful interference caused by in-band external radiators. • Number of BaseStations. • Number of BeltStations per BaseStation. • Whether or not Accu-Sync or ZSync is being employed. • Physical location of BaseStation antennas (either on BaseStations or on Transceivers). • Physical location of the BeltStations.
Seamless Roaming Tempest Seamless Roaming is a powerful feature that allows a BeltStation to automatically seek-out and move to a different BaseStation than the one it is currently on, with no user intervention. This feature can provide increased coverage area, and system flexibility for those users who need it. Because all of the roaming decision making takes place within the BeltStation, individual BeltStations can be set to roam or not to roam, and programmed to BaseStations they desire to roam between.
Coverage Planning Placing your antennas for Tempest Seamless Roaming follows the same basic rules of any multi-BaseStation Tempest wireless system with one exception. The antennas do not need to be located in the same physical location. For example, let’s look at a two BaseStation system utilizing two Remote Transceivers: A venue has two large rooms separated by a hallway. Each room needs Tempest coverage and the ability for users to work and move freely from room to room.
How Do I …? Remove Batteries from BeltStations Remove the battery cover from the back of the BeltStation by pressing lightly on the thumb grooves and sliding towards the bottom. Hold the BeltStation in one hand with the battery compartment facing downward over the open palm of your other hand. Firmly tap the BeltStation against the palm of your open hand and the battery will fall into your open hand. Follow the same procedure for AA batteries.
Adjust Min/Max BeltStation Volume Levels From the BeltStation: • To set the Minimum volume, press MENU, select “Set Controls,” then “Volume Limit” and “Min Volume.” Use the Volume knob to adjust the level and press ENTER to save the new setting. • To set the Maximum volume, advance to “Volume Limit” as above, and then “Max Volume.” Use the Volume knob to adjust the level and press ENTER to save the new setting.
Configure Relays for Individual BeltStations From the BeltStation: • Press MENU; select “Set Controls,” select “Select Relay.” Note that there are more options under “Set Controls” than fit on the screen. Scroll to the bottom of the screen and scroll one more detent to see the “Select Relay” option. Select one of the relays: Relay 1 thru Relay 5. When a relay is selected a check mark will be visible beside the selection. • To activate the relay, a “Relay Button” must be triggered.
Update the Firmware (with CodeUpdater) Tempest firmware updates are released periodically, and equipment should be updated to maximize optimal system performance. Staying up to date with the latest firmware ensures that your system is equipped with the newest features and enhancements that Tempest has to offer. Tempest uses a proprietary program, CodeUpdater, to update firmware in the BaseStation and the BeltStation.
Troubleshooting BaseStation Limited RF range BaseStation antenna or transceiver should be located as high as possible. Locating the BaseStation antenna above head level is critical for optimizing performance and range. • Confirm that BaseStation antenna or transceiver are in an appropriate location and orientation. • Confirm that antenna or transceiver are not close to any metal structures or racks; locate the BaseStation and BaseStation antenna or transceiver away from potentially interfering devices.
No audio passing when not using an external hardwired intercom system and Tempest BaseStations are sharing intercom channels. • Confirm that no wired intercoms are connected to the system. • Confirm a 3-pin XLR cable connection for each channel to be shared, between each of the BaseStations. • Set the BaseStation 2-Wire Intercom Type Select Switch to the Clear-Com position. • Select 2-Wire for the relevant channels. Set only one of the Tempest BaseStations to Master Mode.
BeltStation BeltStation will not power up • Confirm that battery(ies) is (are) installed correctly. • When using a Lithium-Polymer rechargeable battery, ensure that the battery is fully charged. • When using alkaline AA batteries, ensure that batteries are fresh and are all facing the same way. Note the illustration in the battery compartment section. • Press and hold the Power button on the back of the BeltStation for two seconds to power ON.
Buttons on the BeltStation do not function A number of buttons on the BeltStation can have alternate functions that the user can select. If a button on the BeltStation is not working as expected, re-confirm all settings and any alternate function assignment in the menu. The button may have been reassigned wirelessly from the BaseStation or by T-Desk. Confirm that the function is available for use.

Glossary 2-Wire or TW: A type of intercom system characterized by audio signals transmitted and received on the same pair of wires at the same time. The connector usually associated with 2-Wire or TW is a 3-pin XLR. 4-Wire: A type of intercom system characterized by audio signals transmitted on one pair of wires and received on a different pair of wires.
Full Duplex: Simultaneous two-way conversations (i.e. telephone communication). GPIO: General Purpose Input Output – a simple device control method. Half Duplex: Two-way conversations, one-way at a time, such that one person cannot interrupt the other (i.e. walkie-talkie). IFB: Interrupted Feedback, or Interrupted Fold-Back - The IFB system connects control room personnel such as the director, or producer with the performers or “talent.
Time Domain Multiple Access (TDMA): Radio technology that takes advantage of the relatively slow speed of sound and much faster speed of RF, to create the illusion of multiple simultaneous transmissions. Tempest BaseStation: The control station for a group of Tempest Wireless Intercom BeltStations with the ability to interface with most commonly used wired intercom systems.
