3 Getting started This section gives an overview of your P25 radio, describes the radio’s controls and indicators, and explains how the radio menus are organized.
About P25 digital radios Your P25 digital radio can be programmed for P25 conventional or P25 trunked operation. Analog conventional operation is also available, with dual-mode channels able to receive both digital and analog calls. You may notice differences between digital and analog calls in terms of: ■ static noise in low signal areas, and ■ radio coverage in marginal reception areas. Lack of static noise On digital networks there is no static noise, even in low signal areas.
About the radio controls The radio controls are the PTT key, power/volume control, channel selector, 3-way selector control (optional), scroll keys, selection keys, and function keys. Some keys have functions assigned to both short and long key presses: ■ a short key press is less than one second, and ■ a long key press is more than one second. The radio controls and their functions are described in the following sections.

Understanding the radio display The messages and icons you see on your radio display depend on the mode in which your radio is operating and the way it is programmed.
Icon Meaning Scanning: your radio is monitoring a group of channels or talkgroups for activity, and the currently selected channel or talkgroup is a member of the scan group.
Understanding the radio indicators The status LED indicator and the radio’s audible tones— together with the radio display—all combine to give you information about the state of your radio. The most common way the indicators work is described in the following sections. The way these indicators behave may be affected by the way your radio is programmed.
Audible tones The radio uses audible tones to alert you to its status: ■ Radio controls and keypress tones—the tones and beeps you hear when you press your radio’s keys or use the controls. ■ Incoming call tone—when the radio is receiving a call. ■ Warning tones—when there is an error, or the battery is low, for example. If quiet or silent mode is turned on, you will not hear any alert tones.
Using function keys to access frequently used features The function keys provide access to some of the features you will use most often. These features are assigned to the function keys when the radio is programmed. Some keys may have a feature associated with both a short key press and a long key press.

Receiving calls When a call is received with valid signaling, the radio unmutes and you can hear the call. Identifying a caller (talking party ID) This feature is available for digital channels only. You can use talking party ID to identify the radio user calling you. (This feature is usually turned on when the radio is programmed.) ■ talkgroup call: the name of the talkgroup is displayed.
Receiving a two-tone call This feature is available for analog channels only. Two-tone signaling is used to call either individual or groups of radios. When your radio receives a two-tone call that it can decode, it beeps, indicating which type of two-tone call has been received. ■ One long beep: a two-tone individual call has been received. ■ Two medium beeps: a two-tone group call has been received. ■ Three short beeps: a two-tone super group call has been received.
Communicating directly with other radios You can bypass the radio repeater and communicate directly with another radio using the radio talkaround feature. You can do this when you are out of range of the repeater, or if the repeater is busy. While repeater talkaround is active, all calls are made on your current channel’s receive frequency. Turning repeater talkaround on and off You can turn repeater talkaround on and off using a function key, if your radio is programmed in this way.
Checking that the channel is clear Monitor allows you to override some or all of the radio’s mutes, allowing you to hear if there is any traffic (including talkgroup and individual calls) on a channel. For analog channels, this is so that you can check that the channel is clear before you make a call. Turning monitor on and off 1 Press Menu and select Radio settings > Functions > Monitor. (Depending on how your radio is programmed, you may be able to press a function key to toggle monitor on and off.
Using the radio in different repeater areas Your radio may have a group of channels programmed as a voting group. The channels in the voting group all carry the same traffic, but from different repeaters. As your radio moves in and out of different repeater coverage areas, the best communication channel is automatically selected for you to use. This channel is known as the ‘home’ channel, and may be the channel you make and receive calls on. While voting is active, appears in the display.
2 Scroll to the group you want and press Select. Channels Vote 1 Channel 9 Back Select Suspending a channel from a voting group You may be able to use the function key programmed for ‘nuisance delete’ to temporarily remove one of the channels from the voting group. To remove a channel from a voting group: 1 Wait until the radio has stopped on the channel that you want to remove from the voting group. 2 Press the function key programmed for nuisance delete.
Scanning a group of channels The scan feature is used to monitor a group of channels for activity. When there is activity on a channel in the group, the radio stops on that channel. The radio then unmutes and you can hear the call. Scanning resumes when the channel is no longer busy. Some channels, known as ‘priority’ channels, are scanned more often that other channels in the group. While the radio is scanning for activity, appears in the display.
Activating standard scanning Standard scanning is activated when you select a standard scan group. To select a standard scan group: 1 Press Menu and select Channels. (Depending on how your radio is programmed, you may be able to press a function key or use the channel selector or Quick Access menu to select channels.) 2 Scroll to the group you want and press Select. Channels Scan 1 Channel 9 Back Select Activating background scanning Background scan is turned on using a programmed function key.
Activating in-zone scanning In-zone scan is turned on using a programmed function key. While in-zone scan is active, the radio scans all the channels programmed for the zone in which the radio is operating. When you change to another zone, in-zone scan starts with channels in the new zone. To turn in-zone scan on: ■ Press the function key. In-zone scan remains on until either you press the function key again, or select a standard or background scan group.
Suspending a channel from a scan group If a member channel of a scan group is busy for a long time and you do not want to hear the conversation, you may be able to use the function key programmed for nuisance delete to temporarily delete it from the scan group. When the scan group is next selected, or after the radio has been turned off and then on, the deleted channel is again part of the scan group.
Hearing faint and noisy signals This feature is only applicable to analog channels. Usually the radio’s squelch mute (known as ‘squelch’) prevents you from hearing faint or noisy calls on a channel. Without squelch, the radio’s speaker would ‘chatter’ in low signal strength areas. On occasions when you want to hear everything that is being said on a channel, even if it is hard to understand, you can use the squelch override feature to force the mute open.
6 Operating in P25 trunking mode This section explains how your radio operates on a P25 trunking system. This includes how to make group calls, individual calls and phone calls. The features described in this chapter are only available for radios configured for P25 trunking operation.
About P25 trunking Your radio may be able to operate on a P25 trunking system as well as a conventional repeater-based system. On a conventional system, radio users compete for access to individual channels, and one channel can be overloaded with traffic while others are often unused. The trunking system allows several channels to be automatically shared by a number of radio users. These traffic channels are pooled and allocated, as required, for the duration of a call.
Service is lost If access to the trunking system is lost, no longer appears, the bars in the RSSI icon disappear , and the display shows No service. Talkgroup 1 No service Menu The radio sounds five beeps to indicate the loss of service, followed by a repeating double beep. The double beep continues until service is restored. Site trunking operation During normal trunking operation, your radio may roam between a number of sites, each with its own zone controller.
Making a talkgroup call A talkgroup is a collection of radios on a trunking system. Trunked talkgroups are found in the Channels menu, along with conventional channels that may also be available for the currently selected zone. Depending on how your radio is programmed, you may be able to press a function key, use your Quick Access menu or use the channel selector to select a trunked talkgroup. Caution In some situations, your call will not proceed.
2 Select the required talkgroup: ■ Press Menu and select Channels. ■ Scroll to the talkgroup you want, and press Select. Channels Talkgroup 2 Channel 1 Back Select (Depending on how your radio is programmed, you may be able to press a function key, use your Quick Access menu or use the channel selector to select a talkgroup.) Your radio now indicates the currently selected talkgroup.
Receiving a talkgroup call To hear calls from other members of a talkgroup, your radio must have that talkgroup selected, or the talkgroup must be part of an active scan group. For information about selecting a talkgroup, see “Making a talkgroup call” on page 67, and for information about scanning talkgroups, see “Scanning a group of talkgroups” on page 70. When you receive a call from a talkgroup, the radio displays the name or the identity of the talkgroup, and that of the calling radio.
Scanning a group of talkgroups The scan feature is used to monitor a group of trunked talkgroups for activity. Each group of talkgroups is programmed as a single scan group. When there is a call from a member of the talkgroup scan group, the radio unmutes and you can hear the call. Calls from talkgroups programmed as ‘priority’ talkgroups, take precedence over those from a non-priority talkgroup. While the radio is scanning for activity, appears in the display.
To remove a channel from a talkgroup scan group: 1 Wait until the radio has stopped on the talkgroup that you want to remove from the talkgroup scan group. 2 Press the function key programmed for nuisance delete. If the talkgroup has been removed successfully, the message Channel nuisance deleted appears in the display. Channel nuisance deleted The talkgroup remains removed from the talkgroup scan group until you either select another talkgroup scan group or the radio is turned off and then on again.

Emergency calls In an emergency, you can summon help by sending an emergency call. When an emergency call is initiated, the radio enters ‘emergency mode’.
Making a phone call This feature is only available for radios with alphanumeric keys. You may be able to use your radio to connect to a telephone network and make a phone call. Caution In some situations, your call will not proceed. For an explanation of the radio behavior, see “Unconnected calls” on page 75. To make a phone call on a trunking system: 1 Press Menu and select Phone call. (The phone call you last dialed appears in the display.
Unconnected calls If your call is not connected, the way your radio behaves is explained in the following table. Radio behavior System queued Busy channel now free Explanation The system is too busy to process your talkgroup or individual call. The system is now available to process your talkgroup or individual call. The radio sounds three short beeps. You have selected a talkgroup that does not currently exist on the Menu system.
Failsoft mode operation If your radio is unable to access the trunking system, it may be programmed to enter failsoft mode. Failsoft mode operates in one of two ways: ‘radio-based’ failsoft and ‘infrastructure’ failsoft. Radio-based failsoft When you loose access to the trunking system, no longer appears, the bars in the RSSI icon disappear and the display shows No service. , Talkgroup 1 No service Menu After a short time, your radio switches to a programmed conventional communications channel.
You may still be able to communicate with your dispatcher and other talkgroup members, depending on the type of system failure that has occurred, and how your radio is programmed. When the trunking system returns to normal operation, your radio is notified, and will attempt to register on the control channel it was previously using. Dynamic regrouping The dynamic regrouping feature allows you to send a dynamic regrouping request to your dispatcher.

In the Emergency Menu, you can manually acknowledge the duress emergency call. This acknowledgement cancels the call. 1 Press Menu and select Emergency > Acknowledge.
About the lone worker feature Lone worker is a safety feature for people who work alone. The radio requests a response from you at regular predetermined intervals. If you are unable to respond, the radio either enters emergency mode or sends a status update to a predetermined person or talkgroup. An audible warning is given one or two minutes before the radio enters emergency mode or sends the status update, to warn you and to prevent false activation.
About the man down feature The man down feature activates when the radio is tilted more than 60 degrees (for example, the radio user has been attacked and is lying on the ground). If the radio remains in this position for one or two minutes, it will beep to warn the radio user. If you do not respond after a further beep, the radio either enters emergency mode or sends a status update to a predetermined person or talkgroup.
10 Encryption This section describes how to use encryption to make your communications completely private.
About encryption The encryption feature is available for digital and dual-mode channels only. To make communications with other users on your system completely private, your radio may be able to encrypt outgoing calls, using a confidential encryption key. The radio receiving your call must have the same encryption key installed before it can hear your encrypted call. About the proper key detect feature Your radio may be programmed with ‘proper key detect’.
Encrypting calls Your radio may be able to turn encryption on and off. While encryption is on, your outgoing calls are encrypted on channels programmed for encryption, and the encryption icon remains in the display. This setting only affects outgoing calls. Incoming calls will still be decoded by your radio so long as the key required to decode the call is stored in your radio. To turn encryption on or off: 1 Press Menu and select Security > Encryption.

To achieve the best results when charging your battery: ■ Before you begin to charge your battery, make sure that the battery temperature is close to the room temperature in which the battery is to be charged. ■ If possible, charge the battery in temperatures between 50 °F and 77 °F (between 10 °C and 25 °C).
continue while the ignition is off, and consider what effect this might have on the vehicle battery. To check, place the battery in the charger, and switch off the vehicle ignition: ■ If no charger LED stays lit, the charger will resume charging only when the ignition is switched on again. Minimal charger standby power will be drawn from the vehicle battery until then.
Low battery warning Notice Do not allow a radio battery to fully discharge every time you use it, or you will shorten the service life of the battery. When the battery is low, your radio warns you in the following ways: ■ The battery icon on the radio display looks empty. ■ The status LED on the radio slowly flashes red. ■ A high-pitched beep sounds. You should recharge or replace the battery as soon as possible. When the battery is completely empty, the message Battery is flat appears on the display.
Charging the battery Fully charge a battery before using it for the first time. This will take up to 2.5 hours. The red LED stays lit while the battery charges. To charge the battery: 1 Desktop charger: Connect the charger to the correct Tait power adaptor. Multicharger and vehicle charger: Power on the charger. Initially, all three LEDs are lit for two seconds. 2 Place just a battery in the charger, or a radio with a battery attached (desktop charger or multicharger only).
LED behavior If there is a battery in the charger when power is supplied to the charger, the LEDs behave as follows: LED Meaning briefly The charger has been connected to a power supply. The battery is charging. steady steady Charging complete. Remove the battery, or leave it in the charger. ■ The battery temperature is outside the normal charging range. Charging will start or resume once the temperature is within normal limits. No action is required. ■ There is a fault.
Removing the battery from the charger ■ Desktop charger and multicharger: Lift the battery/ radio out of the charger. ■ Vehicle charger: Pull the release bar up, and then lift out the battery. You can remove a battery/radio from the charger at any time without harming the battery, the radio, or the charger. When you return the battery/radio to the charger, charging is automatically resumed. You can also leave a battery/radio in the charger once charging is complete.
Cleaning the contacts of the battery Notice Do not scratch or scrape the contacts of the battery. If necessary, wipe the contacts of the battery with a dry, lint-free cloth to remove any dirt, oil or grease. Storing batteries When not in use for a month or more, batteries should be stored correctly to prolong their life. ■ Remove the battery from the radio before storage. ■ Fully charge the battery if storing for less than one month.
