D Transmitting Notes; D Dtmf Transmission - Icom IC-F15 Instruction Manual

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 only' channel.
• Time-out timer
After continuous transmission for the pre-programmed time period,
the time-out timer activates, and causes the transceiver to stop
transmitting.
• Penalty timer
Once the time-out timer activates, transmission is further inhibited
for a period determined by the penalty timer.
• PTTID call
The transceiver sends the ID code (5-tone, DTMF or digital ANI)
automatically when [PTT] is pushed (beginning of transmission)
and released (end of transmission) depends on the setting.

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.
