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)
- The selected channel is a ‘receive only’ channel.
*Digital mode operation only.
• Time-out timer
After continuous transmission for the pre-programmed time
period, the time-out timer is activated, causing the transceiver
to stop transmitting.
• Penalty timer
Once the time-out timer is activated, transmission is further
inhibited for a period determined by the penalty timer.
