Transmitting notes
• Transmit inhibit function
The transceiver has several inhibit functions which restrict
transmission under the following conditions:
- The channel is in the ‘Inaudible’ (mute) mode
- The channel is busy.
- The channel is busy. However, depending on the prepro-
grammed settings, you can transmit when the call includes
an unmatching (or matching) CTCSS (DTCS).
- The selected channel is a ‘receive only’ channel.
• Time-out timer
If continuous transmission exceeds the pre-programmed
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 pre-programmed penalty
timer period.
• PTTID call
The transceiver automatically sends the 5-tone, DTMF or
digital ANI ID code when [PTT] is pushed (beginning of the
transmission), and/or when it is released (end of transmis-
sion), depending on the preprogramming.
A PTTID call also be made with the MDC 1200 signal-
ing system. (p. 13)

DTMF transmission
If the transceiver has a key assigned to [DTMF Autodial], the
automatic DTMF transmission function is available.
Push [DTMF Autodial] to transmit the DTMF code.
