11 2(a) Listening to the radio
1. Push the
(A/M) or (F/M 1/2) button to
turn the radio on and select either an AM or FM broadcast.

3. Tune in the desired station. (See ª(b) Selecting a
station.º)
The radio will change automatically to stereo reception when
an FM stereo broadcast is being received. At the same time
ªSTº will appear on the display. When the receiving signal
gets weak, the channel separation will automatically be
reduced for lowest noise. If the signal becomes extremely
weak, the radio will switch over to monaural reception.
4. Adjust the tone and sound balance. (See ª(d) Adjusting
the toneº and ª(e) Adjusting the sound balance.º)
5. To turn the radio off, push the ªPWR.VOLº knob.(b) Selecting a station
Tune in the desired station using one of the following
methods. The frequency will appear on the display.
Preset tuning: Use for tuning±in to a desired preset station.
Push the station selector button to which the desired station
has been preset. The radio will tune in to the station and the
button number will appear on the display. See ª(c) Presetting
a station.º)
Seek tuning: Use for automatic station search and stop.
Push the
(SEEK) button and hold it until a beep is heard.
The radio will begin seeking up or down for a station of the

push the button, stations will be searched out one after
another.
Scan tuning: Use for scanning preset stations or
station±to±station scanning.
Push the
(SCAN) button for less than 2 seconds. With
ªP. SCANº blinking on the display, the radio will automatically
seek out a preset station of a higher channel number in the
AM/FM mode. If there is a preset station on the channel,
then the tuning is held for 5 seconds. If there is no station
on the channel, then the tuning is only held for 1 second. If
the
(SCAN) button is pushed while listening to a preset
station channel, then the scan proceeds to the next highest
channel, proceeding in turn through the 6 channels of FM1
and then the 6 channels of FM2, then repeating the process.
To continue listening to the channel of your choice, simply
push the
(SCAN) button once again.

11 4FM reception tips
A vehicle is not an ideal place to listen to a radio. Because
it moves, reception conditions are constantly changing.
Buildings, terrain, signal distance and noise from other
vehicles are all working against good reception. Some
conditions of FM may appear to be problems when they are
not. The following characteristics are completely normal for
a given reception area, and they do not indicate any problem
with the radio itself.
Fading and drifting:
FM range is limited to about 40 km (25 miles), except for
some high power stations.
If a vehicle is moving away from the desired station's
transmitter, the signal will tend to fade and/or drift. This
phenomenon is more noticeable with FM than with AM,
and is accompanied by distortion.
Fading and drifting can be minimized to a certain degree
by careful attention to fine tuning, or you should retune
the radio to another stronger station.
Static and fluttering:
When the line±of±sight link between a transmitter and
vehicle is blocked by large buildings or the like, the radio
sound may be accompanied by static or fluttering
because of the characteristics of FM. In a similar effect,
a fluttering noise is sometimes heard when driving along
a tree±lined road.This static and fluttering can be reduced by adjusting the
tone control for greater bass response until the
disturbance has passed.
Multipath:
Because of the reflecting characteristics of FM, direct
and reflected signals may reach the antenna at the same
time (multipath) and cancel each other out. As a vehicle
moves through these electronic dead spots, the listener
may hear a momentary flutter or loss of reception.
Station swapping:
When two FM stations are close to each other, and an
electronic dead spot, such as static or multipath area,
interrupts the original signal, sometimes the stronger
second signal will be selected automatically until the
original one returns. This swapping can also occur as
you drive away from the selected station and approach
another station with a stronger signal.

or about 20 dB total. For best sound reproduction, select the
same NR mode that was used to record the tape. To play a
tape recorded without Dolby NR*, push the button until the
Dolby NR indicator disappears.
