D Transmitting notes

• Transmit inhibit function

The transceiver has several inhibit functions which restrict

transmission under the following conditions:

- The channel is in mute condition (‘Inaudible’ condition;

“ ” does not appear.)

- The channel is busy.

- Un-matched (or matched) CTCSS is received.

(Depending on the pre-setting.)

- Un-matched (or matched) NAC is received*.

(Depending on the pre-setting.)

*Digital mode operation only.

- The selected channel is a ‘receive only’ channel.

• Time-out timer

After continuous transmission for the pre-programmed time

period, the time-out timer is activated, causing the trans-

ceiver to stop transmitting.

• Penalty timer

Once the time-out timer is activated, transmission is further

inhibited for a period determined by the penalty timer.
