Transmitting notes
D
• Transmit inhibit function
The transceiver has several inhibit functions which restrict
transmission under the following conditions:
- The channel is busy. However, depending on the pre-
programmed settings, you can transmit when the call
includes an unmatching (or matching) CTCSS (DTCS),
RAN code*, or Individual or Talkgroup ID*.
* Digital operation only
- The selected channel is a ‘receive only’ channel.
• Time-out timer
If continuous transmission exceeds the preprogrammed
time-out timer limit, the transmission is cut off.
• Penalty timer
After the transmission is cut off by the time-out timer, trans-
mission is further inhibited for the preprogrammed penalty
timer period.
