D Transmitting notes

• Transmit inhibit function
The transceiver has several inhibit functions which restrict trans-
mission under the following conditions:
- The channel is muted.
- The channel is busy.
- A signal with an un-matched CTCSS (or DTCS) tone is re-
ceived.
- The selected channel is a 'receive only' channel.
• Time-out timer
The transceiver has a time-out timer function which prevents con-
tinuous, extend transmissions.
After continuously transmitting longer than the preprogrammed
time period, the Time-out timer function activates, and stops further
transmitting.
• Penalty timer
Once the time-out timer function activates, transmitting is further
inhibited for a time period determined by the penalty timer.
