D Transmitting notes
•Transmitinhibitfunction
The transceiver has several inhibit functions which restrict
transmission under the following conditions:
- The channel is muted (‘Inaudible’ mode)
- The channel is busy.
- Un-matched CTCSS is received.
(Or matched, depending on the preprogramming)
- The selected channel is a ‘receive only’ channel.
•Time-outtimer
After continuously transmitting for the pre-programmed time
period, the time-out timer is activated, causing the trans-
ceiver to stop transmitting.
•Penaltytimer
Once the time-out timer is activated, transmission is further
inhibited for a period, determined by the penalty timer.
•PTTIDcall
The transceiver automatically sends the 5-tone, DTMF or
digital ANI ID code when [PTT] is pushed (beginning of the
transmission),and/orwhenitisreleased(endoftransmis-
sion), depending on the preprogramming.
A PTTID call also be made with the MDC 1200 signal-
ing system. (p. 13)
D DTMF transmission
If the transceiver has [DTMF Autodial] assigned to it, the au-
tomatic DTMF transmission function can be used.
Push [DTMF Autodial] to transmit the DTMF code.
