FRONT PANEL FACILITIES
_99MPX MODE selector button
Use to select the auto stereo mode or monaural mode when listen-
ing to FM broadcasts. The monaural mode has been selected
when the MONO indicator is lighted.
Auto stereo mode:
Normally leave in this mode for reception. When a stereo FM
broadcast is received, it will be automatically reproduced in
stereo sound.
Monaural mode:
When receiving distant stations or stations with weak broadcast
signals, the input signal may be weak, thus resulting in increased
noise during FM stereo broadcasts. In this event, setting the
receiver to the monaural mode will reduce the noise. In this case,
however, FM stereo broadcasts will be reproduced in monaural
sound.
NOTE:
This button has no effect on reception of AM broadcasts.
