D Transmitting notes
• Transmit inhibit function
The transceiver has several inhibit functions which restrict
transmission under the following conditions:
- The channel is in mute condition (‘Inaudible’ condition;
“ ” (Audible icon) does not appear.)
- The channel is busy.
- Un-matched (or matched) CTCSS is received.
(Depending on the pre-setting)
- 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 trans-
ceiver to stop transmitting.
• Penalty timer
Once the time-out timer is activated, transmission is further
inhibited for a period determined by the penalty timer.
• PTTID call
The transceiver sends the ID code (5-tone, DTMF or digital
ANI) automatically when [PTT] is pushed (beginning of the
transmission) and/or released (end of transmission) depend-
ing on the setting.
PTTID call is also available with the MDC 1200 signal
-
ing system. (p. 13)
D TX code channel selection
If the transceiver has [TX Code CH Select] assigned to it,
the indication 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,
[CH Up] or [CH Down] selects the TX code channel.
USING [TX CODE CH SELECT] KEY:
q Push [TX Code CH Select]— a TX code channel number
(or name) appears.
w Push [CH Up] or [CH Down] to select the desired TX code
channel.
e After selecting, push [TX Code CH Select] to set.
• Return to the stand-by mode.
r Push [Call] to transmit the selected TX code.
USING [TX CODE CH UP]/[TX CODE CH DOWN] KEY:
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 when pushed.
