Volume and Squelch
The VOLume and SQuelch controls have each knob. They are independent
controls but work together to control audio output from the speaker. The
volume control sets the loudness of sound from the speaker and the squelch
control is used to mute background noise when no received signals are
present.
To properly set the VOL and SQ controls:
•
Rotate the SQ knob fully CCW.
•
Rotate the VOL knob CW until background noise is plainly heard.
•
Slowly rotate the SQ knob CW until the noise is muted (squelched).
Then adjust the control slightly more CW (approximately 1/8 turn).
Use care not to set the SQ control more CW than necessary or weak
signals may not be heard.
Some channels exhibit more background noise than others, so it may be
necessary to readjust the squelch setting when changing channels or when
scanning.
