BASIC OPERATION
■ Setting squelch level
The squelch function sets a minimum receive signal level

veniently prevents noise and static from being emitted when
receiving weak signals or no signals at all.
Further setting of squelch removes weak signals.The remove
level is displayed on the S-meter (S-meter squelch). The
squelch does not open if a signal below the set S-meter level
is received.
