3 CONVENTIONAL OPERATION

DTransmitting notes

Transmit inhibit function

The transceiver has several inhibit functions which restrict trans- mission under the following conditions:

-The channel is in mute condition (‘Inaudible’ condition; “ ” does not appear).

-Channel is busy.

-Un-matched (or matched) CTCSS is received.

-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 transceiver to stop transmitting.

Penalty timer

Once the time-out timer is activated, transmission is further inhibited for a period determined by the penalty timer.

DTX code channel selection

If the transceiver has [TX Code CH Select] assigned to it, indica- tion 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, the []/[] key selects the TX code channel.

TO SELECT A TX CHANNEL:

qPush [TX Code CH Select]— a TX code channel appears.

w Push []/[] to select the desired TX code channel.

e Push [Call] (or [PTT] during MSK operation) to transmit the se- lected TX code.

r Push [TX Code CH Select] again to return to the operating chan- nel number indication.

FOR TX CODE CHANNEL TYPE:

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.
