BASIC OPERATION

Receiving and transmitting (Continued)
D
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; “
”
(Audible
icon)
does not appear.
- The channel is busy. However, depending on the prepro-
grammed settings, you can transmit when the call includes
an unmatching (or matching) CTCSS (DTCS), RAN code,
or Individual or Talkgroup ID.
- 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, BIIS
or digital ANI ID code when [PTT] is pushed (at the begin-
ning of the transmission), and/or when it is released (at the
end of transmission), depending on the preprogramming.
A PTTID call also be made with the MDC 1200 signaling
system.
D
TX code channel selection
If the transceiver has a key assigned to [TX Code CH Select],
the dysplay 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 key assigned to [TX Code CH Up] or
[TX Code CH Down], the programmed TX code channel can
be directly selected when pushed.
