Transmitting notes
• Transmit inhibit function
The transceiver has several inhibit functions which restrict trans-
mission under the following conditions:
- The channel is in mute condition (‘Inaudible’ condition; “
”
does not appear).
- Channel is busy.
- Un-matched (or matched) CTCSS is received.
- 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 transceiver to stop transmitting.
• Penalty timer
Once the time-out timer is activated, transmission is further inhib-
ited for a period determined by the penalty timer.

can be toggled between the operating channel number (or name)
and TX code channel number (or name). When the TX code chan-
nel number (or name) is displayed, the [
]/[

e
Push [Call] (or [PTT] during MSK operation) to transmit the se-

nel number indication.
FOR TX CODE CHANNEL TYPE:
If the transceiver has a [TX Code CH Up] or [TX Code CH Down]
key assignment, the programmed TX code channel can be se-
lected directly.
