ADJUSTING THE SQUELCH

Squelch is used to mute the speaker when no signals are
present. With the squelch level set correctly, you will hear
sound only while actually receiving a signal. The higher the
squelch level selected, the stronger the signals must be in
order to hear them. You can set the squelch level separately
for Bands A and B.
1 Press [F], [MONI].
The squelch level appears on the display.
2 Press [ ]/[ ] or rotate the [ENC] control of your selected
band, when no signals are present, and select the squelch
level at which the background noise is just eliminated.
3 Press [ENT].
The squelch level is set.

TRANSMITTING

Selecting an Output Power
