DMONITOR AUDIBLE FUNCTION

The monitor function allows you to open the transceiver’s squelch manually to check whether a channel is busy or not. The trans- ceiver has 2 conditions for receive standby:

All signals are received

Only signals con- taining the proper tone are received

DTIME-OUT TIMER

Audible condition:

This condition mutes audio ONLY when no carrier is present. You can receive (or monitor) any signals on a channel.

•Push and hold the [MONI], switch to se- lect the audible condition.

Any audio mute functions are cancelled while pushing the [MONI] switch.

Inaudible condition:

This condition mutes ALL signals except those directed to you. Therefore you should check a channel’s condition (busy or not) with the monitor function before transmitting.

•Push the [MONI] switch momentarily to select the inaudible condition.

After continuous transmission for a pre-programmed period, the time-out timer is activated, causing the transceiver to stop transmit- ting and automatically selects receive.

•The time-out timer function is automatically turned ON when 3 min. has passed.

DPOWER SAVE FUNCTION

The power save function reduces the current drain to conserve bat- tery power.

•The power save function is automatically turned ON when no operation is performed or no signal is received for 5 sec.
