CONVENTIONAL OPERATION

D Transmitting notes
• Transmit inhibit function
The transceiver has several inhibit functions which restrict
transmission under the following conditions:
- 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 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.
