D Transmitting notes
• Transmit inhibit function
The transceiver has several lockout/inhibit functions which re-
stricts the transmission under the following conditions:
➥ The channel is in mute condition (‘inaudbile’ condition;
“
[]
” does not appear).
➥ Channel is busy.
➥ Not matched (or matched) CTCSS is being received.
➥ The selected channel is a ‘receive only’ channel.
• Time-out timer
After continuous transmission for a pre-programmed period,
the time-out timer is activated causing the transceiver to stop
transmitting and automatically select receive.
• Penalty timer
Once the time-out timer is activated, transmission is further
inhibited for a period determined by the penalty timer.
