CONVENTIONAL OPERATION
Receiving and transmitting
NOTE: Transmitting without an antenna may damage the trans-
ceiver. See p. 2 for antenna attachment.
Receiving:
q Rotate [VOL] to turn power ON.
w Toggle [CHANNEL SWITCH] (IC-F14S/F24S), rotate [CHAN-
NEL SELECTOR] (IC-F14/F24) or push one of [MR-CH 1] to
[MR-CH 4] key to select a channel.
For IC-F14S/F24S
:
The memory channels 3 and 4 are available when [MR-CH 3]
and [MR-CH 4] keys are assigned.
e When receiving a call, adjust the audio output level to a comfort-
able listening level.
Transmitting:
Wait for the channel to become clear to avoid interference.
q While pushing and holding [PTT], speak into the microphone at
a normal voice level.
When a tone signalling system is used, the call procedure de-
scribed on p. 13 may be necessary.
w Release [PTT] to return to receive.
IMPORTANT!: To maximize the readability of your signal;
1. Pause briey after pushing [PTT].
2. Hold the microphone 5 to 10 cm (2 to 4 inches) from your
mouth, then speak into the microphone at a normal voice
level.
D Transmitting notes
Transmit inhibit function
The transceiver has several inhibit functions which restrict trans-
mission under the following conditions:
- The channel is in mute condition.
- Channel is busy.
- Un-matched (or matched) CTCSS is received.
- The selected channel is a receive onlychannel.
Time-out timer
After continuous transmission for the pre-programmed time period, the
time-out timer activates, and causes the transceiver to stop transmit-
ting.
Penalty timer
Once the time-out timer activates, transmission is further inhibited
for a period determined by the penalty timer.
D DTMF transmission
If the transceiver has [DTMF Autodial] assigned to it, the automatic
DTMF transmission function is available.
Push [DTMF Autodial] to transmit the DTMF code.
