AUTOMATIC SQUELCH:

I cannot find your particular manual, maybe the below information may be helpful .

The FRS is equipped with an automatic squelch circuitry filtering out weak transmission and unwanted noise, usually caused by terrain conditions.
MONITOR:
- This feature turns off the automatic squelch feature, either momentarily or continuously. It helps in receiving signals to its maximum range, but may pick up static signals, too.
Momentary monitor:
- Press the MON button; the monitor symbol will appear.
- Release the button to restore the automatic squelch.
Continuous monitor:
- Press the MON button for more than 2 seconds until a beep sound is heard. The monitor symbol will appear.
- To restore the automatic squelch, press and release the MON button again.
NOTE: You cannot transmit when the Monitor feature is activated.
