4 BASIC OPERATION

■Monitor function

This function is used to listen to weak signals without disturb- ing the squelch setting or to open the squelch manually even when mute functions such as the tone squelch are in use.

➥Push and hold [SQL] to monitor the operating frequency.

•The 1st segment of the S-meter blinks.

■Attenuator function

The attenuator prevents a desired signal from distorting when very strong signals are near the desired frequency or when very strong electric ﬁelds, such as from a broadcasting sta- tion, are near your location.

➥While pushing [FUNC], push [SQL] to toggle the attenuator function ON and OFF.

• “ATT” appears when the attenuator functions is in use.
