CONVENTIONAL OPERATION
D 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 inhibited
for a period determined by the penalty timer.
D TX code channel selection
If the transceiver has [TX Code CH Select] assigned to it, indica-
tion can be toggled between the operating channel number (or
name) and TX code channel number (or name). When the TX code
channel number (or name) is displayed, the [
]/[ ] key selects
the TX code channel.

q Push [TX Code CH Select]— a TX code channel appears.
w Push [
]/[ ] to select the desired TX code channel.
e Push [Call] (or [PTT] during MSK operation) to transmit the se-

r Push [TX Code CH Select] again to return to the operating chan-
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 selected
directly.
D TX code number edit (PMR or BIIS PMR operation only)
If the transceiver has [TX Code CH Select] or [TX Code Enter] as-
signed to it, TX code contents can be edited within the allowable
digits.
