BASIC OPERATION

Receiving and transmitting
Receiving:
Rotate [VOL] to turn ON the power.
q
Select a channel.
w
Rotate [ROTARY SELECTOR].
➥
Push one of the memory channel keys, [MR-CH 1]
➥
to [MR-CH 4].
When receiving a call, adjust the audio output to a
e
comfortable listening level.
NOTE:
When a matched RX code signal is received,
the transceiver automatically transmits its micro-
phone audio for a specified time period, depending
on the presetting.
Transmitting:
CAUTION:
Transmitting without an antenna will dam-
age the transceiver. See page 1-3 for antenna at-
tachment.
Wait for the channel to become clear to avoid interfer-
ence.
While holding down [PTT], speak into the micro-
q
phone at a normal voice level.
Release [PTT] to receive.
w
NOTE:
To maximize the readability of your signal:
1. Pause briefly after pushing [PTT].
2. Hold the microphone 5 to 10 cm (2 to 4 inches) from
your mouth, then speak at a normal voice level.
Transmitting notes
D
• Transmit inhibit function
The transceiver has several inhibit functions, which re-
strict transmission under the following conditions:
- The channel is muted. (PMR operation only)
- The channel is busy.
- A signal with an unmatched (or matched) CTCSS (or
DTCS) tone is received.
- The selected channel is a ‘receive only’ channel.
• Time-out timer
After continuously transmitting longer than the prepro-
grammed time period, the time-out timer activates, and
stops further transmitting.
• Penalty timer
Once the time-out timer activates, transmitting is further
inhibited for a time period determined by the penalty
timer.
• PTTID call
The transceiver automatically sends the ID code (5-
tone, DTMF or BIIS operations) when [PTT] is pushed
(beginning of the transmission) and/or released (end of
transmission), depending on the presetting.
