Transmitting notes
• Transmit inhibit function
The transceiver has several inhibit functions that restrict
transmissions under the following conditions:
- The channel is busy or a unmatched CTCSS/DTCS
is received. (Depending on the transmission lockout
function setting.)
- The selected channel is a “receive only” channel.
• Time-out timer
After a continuous transmission (example: continuously
holding down [PTT]), a time-out timer will be activated,
causing the transceiver to stop transmitting and automatically
revert to receive.
