Transmitting notes
D
• Transmit inhibit function
The transceiver has several inhibit functions which restrict
transmission under the following conditions:
- The channel is busy or an un-matched CTCSS/DTCS is
received. (Depending on the transmission lockout func-
tion setting.)
- The selected channel is a ‘receive only’ channel.
• Time-out timer
After a continuous transmission (i.e. continually holding down
[PTT]
), a time-out timer will be activated, causing the trans-
ceiver to stop transmitting. In this case, the transceiver will
automatically revert to receive.
