Risk of hearing and material damage
If you set the squelch threshold to a very low value, a very loud hissing
noise can occur in the receiver. This hissing noise can be loud enough to
cause hearing damage or overload your system’s loudspeakers.
▷ Before adjusting the squelch threshold, set the volume of the audio out-
put to the minimum.
▷ Never change the squelch threshold during a live transmission.
