radio will beep twice. The display will show the ID of the calling unit. If the ID
matches one of the Call List IDs, the associated label will be displayed along with the
RX and phone icons. Otherwise the numeric ID will be displayed along with the RX,
phone, and ID icons. The calling unit’s ID will be displayed for the duration of the
reception, and once the signal goes away, for a programmed hold time. When the
hold time expires, the display will return to the normal Operating Mode display, but the
phone icon will flash until the [*] key is pressed, putting the radio in Unit-To-Unit
Mode, displaying the last active ID.
3.12.4 UNIT-TO-UNIT CALLBACK
If Unit-To-Unit callback is enabled, and a Unit-To-Unit call is received on the Ready-
to-Transmit (RTX) channel, the user may press PTT before the hold time expires,
causing the radio to enter Unit-To-Unit Mode and transmit using the received ID as
the destination ID. If the callback timer expires before PTT is pressed, the radio will
return to normal Operating Mode, but the phone icon will flash until the [*] key is
pressed, bringing up the last active ID.
To exit Unit-To-Unit Mode, press and hold the [*] key.
The callback timer can be cleared by making the held channel invalid. For instance,
if a scan channel is being held, turn scan off.
3.12.5 PROGRAMMING UNIT-TO-UNIT CALL LIST
Press [*] to bring up the last active ID. If the last active ID was a Call List ID, the ID’s
label will be displayed along with the phone icon. Otherwise, the ID number will be
displayed along with the phone and ID icon.
Press a number key (0 – 9) to go directly to the desired Call List ID, or press [PRI]
repeatedly to cycle to the label of the ID to be re-programmed. Press and hold the
[FCN] key to enter ID Programming Mode (PRG icon will be illuminated). As in
keypad Programming Mode, normal radio function will be disabled until ID
Programming Mode is exited.
