squelch level correctly set, you will hear sound only while actually receiving signals. The

higher the selected squelch level, the stronger the signals must be to receive.

The appropriate squelch level depends on the ambient RF noise conditions.

1. Press 【MENU】key, and then press【MENU】.

The current squelch level appears.

2. Press【▲/▼】key to adjust the level.

Select the level at which the background noise is just eliminated when no signal

the internal timeout timer generates a warning beep and the transceiver stops transmitting.

In this case, release【PTT】and let the transceiver cool down for a while, then press【PTT】

again to resume transmission.
