13 CONVENTIONAL MODE OPERATION
The radio functions in the conventional mode when using conventional communications channels (non-
trunked). Each channel consists of a preset frequency pair for transmit and receive during repeater
operation or a single frequency for both transmit and receive during talk-around (no repeater) operation. To
use this mode, the operator selects a conventional system that includes one or more conventional channels.
Each conventional channel may have one or more features, such as Channel Guard, programmed when the
channel is selected.
The c button unmutes the receiver so activity on the selected channel can be monitored. When pressed
and held for approximately 3 seconds this button toggles conventional channel decoding (Channel Guard,
Digital Channel Guard or T99) ON and OFF, if programmed for the selected channel.
13.1 RECEIVING A CALL
1. Turn the radio on by rotating the POWER ON-OFF/VOLUME knob clockwise (out of detent).
A short alert signal (if enabled through programming) indicates the radio is ready to use.
2. Adjust the POWER ON-OFF/VOLUME knob to the desired volume level.
3. Select the desired conventional system and channel. The display indicates the current
conventional system and channel names.
4. The radio is now ready to receive calls.
5. When the radio receives a call (and the correct encoding is decoded, if programmed and enabled),
it unmutes on the channel and the BSY indicator comes on.
13.2 SENDING A CALL
1. Turn ON the radio and set the POWER ON-OFF/VOLUME knob to the desired volume level.
Select the desired conventional system and channel.
2. Ensure that the channel is not busy by pressing the c button to briefly disable any channel
decoding and unmute the receiver or observe the unlit BSY indicator. If the Channel Busy
Lockout feature is programmed for the selected channel, the radio will not transmit when the
channel is busy.
3. Press and hold the PTT button. The TX indicator will turn on and a short beep sounds (if
programmed) indicating that communication can begin.
4. Hold the microphone approximately three inches from the mouth and speak in a normal voice.
5. Release the PTT button when the transmission is complete and listen for a reply.
13.3 EMERGENCY OPERATION
If enabled, G-STAR emergency signaling can be transmitted when operating in the conventional mode.
This G-STAR signaling will transmit 5 times with a delay between each transmission. To send an
emergency call on the selected conventional system and channel (or on an optionally pre-programmed
conventional emergency system and channel), proceed as follows:
Press and hold the red E or “
E” button for approximately one second (this time is programmable and,
therefore, could be longer or shorter; check with the system administrator). The radio turns on the TX
indicator and proceeds to transmit the pre-programmed G-STAR emergency signaling sequence.
G-STAR is programmed to transmit in one of the following methods:
