The transceiver has several inhibit functions which re-
strict transmission under the following conditions:
- The channel is busy.
-  An  unmatched  CTCSS  tone  or  DTCS  code  is  re-

ceived, depending on the presetting.

-  An  unmatched  or  matched  RAN  code  is  received, 

depending on the presetting.

- The selected channel is a ‘receive only’ channel.

After  continuous  transmission  for  a  preset  time  pe-
riod, the time-out timer causes the transceiver to stop 
transmitting.

Once transmission is cut OFF, it is further inhibited for 
a period determined by the TOT Rekey timer.

The MDC 1200 signaling system enhances your trans-
ceiver’s capabilities. It allows PTT ID signaling.
When  you  push  or  release  [PTT],  the  transceiver 
sends your unit ID, if preset.

When receiving a PTTID

from unit ID ‘0001.’
