Rotate the VOL knob to adjust the receiver's audio volume. Clockwise rotation of the
VOL knob increases the volume level.

The VR-500's Squelch system allows you to mute the receiver's audio output when no
signals are being received. This reduces battery consumption, and reduces annoying
background noise.
ƒ
To set the squelch, turn the
SQL
knob fully counter-clockwise, then turn it clockwise
just past the point where background noise is silenced. Do not rotate the
SQL
knob
much beyond this threshold point; if you do, the receiver will not respond to weak
signals.
