8 Tuning Selector: Press the left side of the button
to tune lower-frequency stations and the right side of
the button to tune higher-frequency stations. When a
station with a strong signal is reached, the
Tuned
Indicator
Q will be illuminated in the Main
Information Display
Û.
In Manual tuning mode, tap the button lightly and note
that the tuner will step up one frequency increment per
button press. When the button is held for a few sec-
onds you will note that the unit will quickly advance
through the frequency band. Release it and the tuner
will stop. In Auto tuning mode, each press of the but-
ton will search for the next station with an acceptable
signal. Press and hold the button to skip through the
acceptable stations. When the button is released, the
tuner will not stop until it reaches a station with an
acceptable frequency.
To switch back and forth between the Auto and
Manual tuning modes, press the
Tuning Mode
Selector
@.
9 AM/FM Selector: Pressing this button will auto-
