“AM”, “FM1” or “FM2” will appear on the display.
The radio can also be turned on by pushing the “PWR.VOL”
knob if the radio had been on when the system was turned off.
3. Turn the “PWR.VOL” knob to adjust the volume.
4. Tune in the desired station. (See “(b) Selecting a station”.)
The radio will change automatically to stereo reception when
an FM stereo broadcast is being received. At the same time,
“ST” 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.
5. Adjust the tone and sound balance. (See “(d) Adjusting the
tone” and “(e) Adjusting the sound balance”.)
6. To turn the radio off, push the “PWR.VOL” 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 “(c) Presetting
a station”.)
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 nearest
frequency and will stop on reception. Each time you push the
button, stations will be searched out one after another.
Scan tuning: Use for scanning preset station channels or
station-to-station scanning.
Push the
(SCAN) button for less than 2 seconds. With “P.
SCAN” 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.

Radio operating tips
The antenna automatically extends to full height when the
radio and ignition are turned on and retracts when either is
turned off.
CAUTION:
Before extending the antenna, confirm that no one is close
enough to get injured.
NOTICE:
To prevent damage to the antenna, make sure it is
retracted before running your vehicle through an
automatic car wash.

99 FM 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 with static or fluttering because
of the characteristic 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.

104Cassette tape player operating tips
Use only cassette tapes of good quality, having no
damage. Avoid using tapes with a total playing time longer
than 90 minutes.
Using damaged tapes may cause harm to the tape player.
Longer tapes are not recommended because of their thinness.
Be sure that the tape is not slack and that the label is firmly
stuck on the shell before insertion.
Wind the tape firmly by turning the hub with a pencil or the like.
Be careful not to touch the tape surface.
When not in use, take the cassette out of the player, put it
back into its case and store it away from dust, magnets
and direct sunlight.
Leaving cassettes on the dashboard in the sun could damage
your tapes.
Keep the interior mechanism of the cassette player clean.
Once or twice a month, use a wet type cleaning cassette to
clean off tape coating residue accumulated on the head,
capstan and pinch roller.
NOTICE:
Do not oil any part of the player and do not insert
anything other than cassette tapes into the slot, or the
tape player may be damaged.
