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, which
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 un-mutes 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.
RECEIVING A CALL
1. Turn ON the radio by rotating the
POWER ON-OFF/VOLUME
knob
clockwise (out of detente). 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 un-mutes on the channel and the
BSY
indicator comes on.
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
momentarily disable any channel decoding and un-mute 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.
