RADIO ALIGNMENT
• Setting SQUELCH (SQL)
The purpose of the squelch control is to mute the speaker when no signals are
present. With the squelch level (1-9) correctly set, the speaker will only un-mute
when there is a sufficient signal present. The higher the squelch level, the
stronger the signals must be to un-mute the speaker. The appropriate squelch
level depends on the ambient RF noise conditions.
1. Press the ‘A’ button on the control head. SQUELCH will be seen on the top
line of the display with the current value on the bottom line.
2. Press the SELECT button and rotate the SELECT knob to the value you want.
It is advised a service monitor generating signal be used to set the
SQUELCH level to your liking. Observe the YELLOW led and the speaker
muting and un-muting as you adjust this setting.

Press the SELECT button to confirm and store the desired setting. To exit
the ALIGNMENT menu press the ‘A’ button.
