CONVENTIONAL MODE OPERATION

Monitoring Before Transmitting

Before transmitting in the conventional mode, regulations require

that you monitor the channel to make sure that it is not being used by

someone else. If you were to transmit while someone else was talking on

the channel, you would probably disrupt their conversation.

The simplest way to monitor the channel is to note if “BUSY” is

indicated in the lower part of the display. If it is not, the channel is not

being used and you can transmit your message. There may be periods

when this indication is displayed and no one is using the channel. There-

fore, other methods to monitor the channel are as follows:

If Call Guard squelch is not used on the channel (refer to description

page 31), monitoring can be performed by simply listening for someone

talking before pressing the push-to-talk switch.

If Call Guard squelch is programmed, it must be disabled so that all

calls can be heard. To disable Call Guard squelch, press the Auxiliary

switch on the side of the transceiver. This turns on the monitor mode

which is indicated by “MON” in the lower part of the display. To re-

enable Call Guard squelch, press the Auxiliary switch again so that

“MON” is not displayed.

Transmit Disable When Busy

The transceiver can be programmed so that the Transmit Disable

When Busy feature automatically disables the transmitter if the channel is

busy (“BUSY” indicated in the lower part of the display). If the channel

is busy with this feature programmed and the push-to-talk switch is

pressed, the transmitter does not turn on and the channel can be moni-

tored for as long as the push-to-talk switch is pressed.

In some systems, “BUSY” may be indicated and the transmitter

disabled even though no one is talking. In this case, the transmitter can be
