The following feature is for the 511DRH only.
(12) Squelch adjust
This adjusts the point at which the receiver will shut off or “squelch” the incoming radio signal when it
becomes too weak. Turning the control clockwise raises the threshold, allowing more signal to enter, and
turning the control counterclockwise lowers the threshold, letting in less signal.
When operating multiple systems all receivers and transmitters must be on the same group
Example: 4 systems operating simultaneously.
To change the frequency that a transmitter, receiver pair is already on
YOU MUST FIRST TURN OFF BOTH THE TRANSMITTER AND RECEIVER!
