Microphone Connector
Allows for convenient removal of the microphone
plug when storage is required. The microphone
MUST be connected to the unit at all times when in
use, for proper operation.
Squelch
This control is used to cut off or eliminate receiver
background noise in the absence of an incoming
signal.
Adjust until the receiver noise disappears.
This will require the incoming signal to be slightly
stronger than average receiver noise. Further clock-
wise rotation will increase the threshold level
which a signal must overcome in order to be heard.
Only strong signals will be heard at a maximum
clockwise setting.
