Other functions to improve FM reception signal quality
MODE button
Normally, press this button so that the “AUTO ST” indicator
illuminates. When receiving an FM stereo broadcast in this
mode, it is received in stereo automatically.
When receiving a weak FM broadcast, press this button so that
the “AUTO ST” indicator goes out. It is received in monaural,
however, you can obtain higher signal quality.
BLEND button
If a noisy FM stereo broadcast is received, press this button so
that the “BLEND” indicator illuminates. The left and right
channels are blended accordingly to reduce the noise and
improve the reception signal quality. When the MODE button
is set to the monaural mode (so that the “AUTO ST” indicator
does not illuminate), the BLEND function will not operate even
if the BLEND indicator illuminates.
IF MODE button
This button is used to vary the bandpass of the FM
intermediate frequency (IF) between WIDE and NARROW.
If the reception signal is strong, press this button so that the
“WIDE” indicator illuminates (to obtain distortion-free sound).
When the reception signal is weak, or when the desired station
is interfered with by adjacent stations, press this button so that
the “NARROW” indicator illuminates (to increase the
selectivity).
