AIR CONDITIONING AND AUDIO
98Push the
(SCAN) button for longer than 2 seconds. With
“SCAN” on the display, the radio will automatically seek out a
station of higher frequency, hold it for 5 seconds and scan to
the next. To continue listening to the broadcast of your choice,
simply push the
(SCAN) button once again.
Manual tuning: Push the
(TUNE) button within 0.5 second.
Each time you push the button, the radio will step up or down
to another frequency where stations could exist.
(c) Presetting a station
1. Tune in the desired station. (See “(b) Selecting a station”.)
2. Push one of the station selector buttons and hold it until a
beep is heard. This sets the station to the button and the button
number will appear on the display.
Each button can store one AM station and two FM stations. To
change the preset station to a different one, follow the same
procedure.
The preset station will be cancelled when the power source is
severed (battery disconnected, burnt fuse, etc.).
(d) Adjusting the tone
To adjust the low-pitched tone, push the “BASS” knob (if
depressed) and turn it.
To adjust the middle-pitched tone, push the “MID” knob (if
depressed) and turn it,
To adjust the high-pitched tone, push the “TREBLE” knob (if
depressed) and turn it.
(e) Adjusting the sound balance
To balance the sound between the right and left speakers,
push the “BALANCE” knob (if depressed) and turn it.
To balance the sound between the front and rear speakers,
push the “FADER” knob (if depressed) and turn it.
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.
