Adjust threshold level of the squelch. A squelch eliminates the
background noise when a signal is not received.
Turn the SQL knob clockwise until white-noise (the background
noise when a signal is not received) and [BUSY] icon on the
display disappears.
The SQL should be turned fully counterclockwise when receiving weak or unstable signals. The [BUSY] icon
appears on the display while the squelch is opened (unmuted).
When you set it to a higher level, weak signals would be interrupted while monitoring or would not be
monitored at all.
Generally, you should set the squelch to the lowest level where noise would be eliminated. Depending on the
monitored frequencies and the conditions of the circumstances around you, the squelch level may need to
be adjusted

Attenuator function is available for SQL knob. (P.44)
