BASIC OPERATION

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 indicator) 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.

• .enalty timer

Once the time-out timer is activated, transmission is further

inhibited for a period determined by the penalty timer.

• .TTID 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) de-

pending 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.
