Tuning into a radio station
1. Press either the AM or FM input selector button.
2. Using the TUNING a/s buttons on the front
panel, tune into the station you desire.
When you tune into a radio station, TUNED indicator appears
in the display. If you tune into an FM station in stereo, then FM
STEREO indicator lights up.
The tuner frequency changes in 50 kHz increments for FM
and 10 kHz increments for AM.
When tuning into FM stations, you can press the TUNING
a/s button continuously for more than 0.5 seconds to
scan for an FM station in the direction of the button you
pressed (FM auto tuning mode). After you release the
button and a station is received in stereo, the scanning
stops.
If no FM station can be tuned in automatically:
If the signal is weak or is too noisy, press the FM MODE
button to cancel the FM MUTE function. This turns the FM
MUTE indicator off and initiates the monaural reception
mode. In this mode, noise between stations is audible but
sound interruption experienced in the stereo reception mode is
removed.
To return to the stereo reception mode, press the FM MODE
button so that the FM MUTE indicator lights up.
