RF GAIN/SQL
RF (default setting)
The RF Gain control provides manual adjustment
of the gain levels for the receiver RF and IF stag-
es, to account for noise and signal strength con-
ditions at the moment.
[RF GAIN/SQL] knob is normally in the fully
clockwise position.
• Before operation, set the operation of
the [RF GAIN/SQL] control to “RF” (see
below). The default setting is “RF”.
• It does not operate in FM/FM-N/
DATA-FM and D-FM-N mode.
SQL
The squelch system allows the back-ground
noise to be muted when no signal is being re-

fault setting is “RF”.
Rotate the [RF GAIN/SQL] knob to adjust the
squelch until the noise disappears.
If the squelch knob is turned too far to the
right, weak signals cannot be heard
