ï Noise blanker
The noise blanker reduces pulse-type noise such as
that generated by automobile ignition systems.
The noise blanker may distort reception of strong sig-
nals. In such cases, the noise blanker should be
turned OFF.

ceiver’s power is ON.

blanker level.
y Push [I/O] to exit the Quick set mode and return to
the normal operating mode.
When using the noise blanker, received signals
may be distorted if they are excessively strong.

AGC OFF function
The receive gain is automatically adjusted according
to received signal strength with the AGC (Automatic
Gain Control) function to prevent distortion from
strong signals and to obtain a constant output level.
When receiving weak signals with adjacent strong
signals or noise, the AGC function may reduce the
sensitivity. In this situation, the AGC function should
be deactivated.
