BUILT-IN FEATURES The BK Radio G Series is based on a microprocessor core that allows extra features and operational characteristics to be programmed into the radio. Your dealer can help define the best operational settings for your system and program them into the radio. PROGRAMMABLE GROUP/CHANNEL SELECTOR 6 5 4 3 9 10 11 12 13 14 2 1 16 15 7 8 The group/channel selector knob can be customized by your dealer to select your preferred group/channel combinations.
PROGRAMMABLE TOP SWITCHES The three top switches can be programmed by your dealer for channel scan, dual priority scan, group scan, low-power select, and RTA (Repeater Talk Around). Your dealer can also assign two functions to the same switch. For example, both low-power select and RTA could be enabled by the same switch.
DTMF ENCODING Keypad-equipped radios can be programmed to enable DTMF (Dual Tone Multiple Frequency) encoding. To send DTMF tones (similar to the tones used by a standard push-button telephone): 1 2 3 FCN 4 5 6 PRI 7 8 9 ENT * 0 # CLR 1. PRESS AND HOLD the PTT switch. 2. PRESS ANY OF THE KEYS on the keypad. You will hear a sidetone. The FCN, PRI, ENT, and CLR keys respond as DTMF tones A, B, C, and D, respectively.
GROUP SCAN Channels on each “channel scan list” and groups on the “group scan list” are scanned sequentially. The knob-selected group is always scanned when group scan is enabled, even if that group is not on the group scan list. When group scan is enabled, the following features are disabled: • Dual Priority Scan • User-Selected Code Guard • Nuisance Channel Delete SCAN DELAY Scan delay lets the radio receive a response to a transmission before scanning the other channels for activity.
DUAL PRIORITY SCAN Up to 2 of the 16 channels in each group can be designated as priority channels. These two channels, PR1 and PR2, are checked at a preset rate (.25–2.0 seconds) for activity, even if you are listening to a different transmission. Activity on PR1 will preempt PR2. Activity on PR2 will preempt any of the non-priority channels. Your dealer can assign dual priority scan to one of the top switches, to the FCN menu, always turned on, or always turned off.
ALPHANUMERIC DISPLAY PRG TX RX SCN ID CG G R P . . . The G Series portable radios are built with one of the following display options: • No keypad and no display or • Keypad and alphanumeric display With obvious exceptions, the operational procedures are the same for both these radios. Radios with a keypad and display have a slide-out keypad cover. To remove or install the cover, turn off the radio and remove the battery (see Battery Installation and Removal, page 28).
GROUP LABELS The display can show group labels in addition to group numbers. To display a group label: 1. SLIDE SWITCHES B (programmed for scan) AND C (programmed for priority scan) DOWN. 1 2 3 FCN 4 5 6 PRI 7 8 9 ENT * 0 # CLR 2. PRESS THE # KEY on the keypad to display the group number. 3. PRESS AND HOLD THE # KEY to display the group label. 4. PRESS THE ENT KEY OR WAIT for about 5 seconds to revert to normal radio operation.
When changing groups, invalid entries will not be accepted, and the radio remains in the previously selected group. 3. PRESS THE ENT KEY or wait 5 seconds. The radio returns to normal operation for the new group, and the selected channel is displayed. All selected scanning and priority functions affect only the channels in the group you are operating in. • 1 2 3 FCN 4 5 6 PRI 7 8 9 ENT * 0 # CLR GROUP SELECTOR. Knob positions 1–15 select groups 1–15. 1. PRESS # TWICE to select a channel.
SCAN OPERATION 1. SLIDE SWITCH B (SCAN) UP. 2. SLIDE SWITCH C (PRIORITY) DOWN. The display indicates scan operation by flashing SCN. SCN Label 3 Scan operates only while the radio is not transmitting. The radio checks for signals on channels in the preset scan list, as well as the channel selected by the channel selector knob. When a signal is detected, scanning stops and the message is received. The received channel is shown in place of the transmit channel.
TALKBACK SCAN If your radio is programmed for talkback scan, press PTT while a channel is active or while scan-delay time remains. You will be responding on the transmit frequency of the received channel. Talkback scan will not work if priority scan is also on and your radio is programmed to always transmit on the Priority 1 channel. SCAN CODE GUARD CHANNELS 1. SLIDE SWITCH B (SCAN) UP. 2. TURN THE SQUELCH KNOB COMPLETELY COUNTERCLOCKWISE, past the detent, to the Code Guard position.
PRIORITY SCAN Priority scan enables the radio to receive on any channel while monitoring for a message on the designated priority channel. The radio samples the priority channel at a preset rate (.25–2.0 seconds) regardless of activity on any other channel. Priority scan operates only while the radio is not transmitting and can be used in combination with scan operation. PR SCN Label 3 When Switch C (priority) is up, the display shows SCN.
Mode A Mode B Mode C Priority Channel Channel Knob Preset Preset Transmit Channel Channel Knob Channel Knob Priority Channel WHICH MODE IS INSTALLED? If the radio has a display and keypad, follow these steps to determine which priority mode is programmed: 1. SLIDE SWITCHES B (SCAN) AND C (PRIORITY) DOWN. 2. TURN THE CHANNEL SELECTOR KNOB, stopping at each channel to view the LCD display. Does PR appear in the display? Yes Turn channel knob to different channel.
Priority Mode A With Scan In Priority Mode A, the priority channel is set by the channel selector knob. Priority Mode A is seldom used by itself because the radio receives and transmits only on the knob-selected channel. PR RX SCN Label 12 BUSY CHANNEL INDICATOR PR RX SCN Label 3 When Switches B (scan) and C (priority) are up, scanning occurs until an active scan channel is found. The radio receives the message while continuing to check the priority channel. The display shows the scan channel.
If activity occurs on the priority channel, the radio overrides the active scan channel, changes to the priority channel, and holds for the duration of the transmission. To reply to a message on the priority channel, turn the channel selector knob to the priority channel, and then transmit. Once activity has ceased on the priority channel, the radio returns to scan operation.
CHANGE THE PRIORITY CHANNEL The fixed priority channel used in Priority Modes B and C can be permanently set or can be changeable. If the radio has a changeable priority channel, use the following steps to make this change. 1. SLIDE SWITCHES B (SCAN) AND C (PRIORITY) DOWN. 2. TURN THE CHANNEL SELECTOR KNOB to the channel you want to enter as the new priority channel. 1 2 3 FCN 4 5 6 PRI 7 8 9 ENT * 0 # CLR 3. PRESS THE PRI KEY.
USER SELECTED CODE GUARD When the radio is being programmed with transmit and receive frequencies for each channel, a receive Code Guard value and a transmit Code Guard value can also be assigned to each channel. If User Code Guard Selection is enabled, the Code Guard values for any channel can be copied to another channel in the radio.
BUSY CHANNEL If the radio has been programmed for busy channel operation, it will operate in one of the following three modes: • Busy Channel Indication • Busy Channel Lockout • Busy Channel Lockout Override BUSY CHANNEL INDICATION BUSY CHANNEL INDICATOR BUSY CHANNEL INDICATOR GPH Owner’s Manual The yellow busy channel indicator glows if there is carrier activity on the selected channel.
BUSY CHANNEL LOCKOUT The busy channel lockout feature applies only to those channels programmed to receive Code Guard operation. When carrier activity is detected on the channel selected, the radio checks the receive Code Guard value. If the proper Code Guard value is present, the radio can transmit on that channel, even if the squelch knob is not in the Code Guard position.
CLONING PROCEDURE STANDARD INSTRUCTIONS Any “master” radio (a GPH Flex•Mode™ with the desired radio frequencies and settings) is capable of transferring its program to another GPH Flex•Mode™ or “slave” radio. The radio receiving the program is also referred to as the “clone.” The LAA0700 cloning cable will be required in the following procedure. 1. MAKE SURE the battery packs for both radios are charged. 2.
9. PRESS THE * KEY on the master radio keypad. The display will flash “PROG” signifying that the radio is ready to download its program to the clone. 10. PRESS THE FCN KEY on the master radio keypad. The program in the master will then be downloaded to the clone. The clone will automatically send back the program to the master to verify a successful cloning. 11. IF THE DOWNLOAD WAS SUCCESSFUL, the display on the master will resume flashing “PROG”.
SPECIAL CLONING INSTRUCTIONS You can change Channel 0 values on the master radio, hold them in a temporary memory, and download them to the clone without actually entering them into the permanent memory of the master. This is convenient if sequential identification numbers are used to identify a series of portables in a radio system.
BATTERY INSTALLATION AND REMOVAL BK Radio battery packs are available in a variety of sizes and types for special applications. Rechargeable battery packs can be charged separately or while attached to a radio. INSTALLING THE BATTERY 1. LOCATE THE CENTER HUB on the radio base and place it in the recess of the battery pack. 2. POSITION THE BATTERY PACK at the 30° offset, seating the two metal studs in their recess. 3. APPLY UPWARD PRESSURE to the pack while twisting the pack to its original position.
