Auto stereo mode:
Normally,
leave in this mode
for reception. When
a
stereo FM broadcast is received, it will be automatically
reproduced in stereo.
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 broad-
casts. !n 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.
