DTransmitting 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.)

-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 transceiv- er to stop transmitting.

• Penalty timer

Once the time-out timer is activated, transmission is further inhibited for a period determined by the penalty timer.
