Five EQ settings

109
EQ (Equalizer)
Your audio system can store five different EQ settings in its memory so that you will not need to readjust in every time you lis-
ten to a different program.
Five common settings are sorted in the
system's memory when it is manufac-tured (see illustration).
To use a preset EQ setting: Push EQº.
The levels for the first setting and EQ-1º
will a
ppear on the display. Push EQº until
you reach the setting you want. The audio
system will adjust the program you are
hearing to the selected setting.
To change a preset EQ setting: Push EQº
until the setting you want to change ap-
pears on the display. Adjust the base, mid-range, and treble levels using the
BASSº, MID/BALº, and TREB/FADEº.
To save an EQ setting: After you have
changed a setting, push EQº until you
hear a beep. This will replace the original factory setting with your new one.
To cancel one of the EQ settings you
saved: With the setting on the display,
push in and hold EQº until you have
heard both the first saveº beep and a sec-
ond beep that means the setting has been
canceled. The original factory setting will
appear on the display. To cancel all of the changed EQ settings: Push and hold in EQº until you hear a third beep.
FADE
This knob lets you adjust the balance be- tween the front and rear speakers.
Push TREB/FADEº so that it pops out of
its retracted position. Pull out the knob.
Turn the knob to adjust the front/rear bal-ance. Push the knob back into its re-
tracted position. MID (Mid-range)
This knob lets you adjust the mid-range level. Push MID/BALº knob so that it pops out
of its retracted position. Turn the knob toadjust
the mid-range level. Push the knob
back into its retracted position. MTL (Metal) Display

tape is put in the cassette player, the play-
er will automatically adapt to it and MTLº
will appear on the display. PROG (Program)
Push PROGº to select the other side of
a cassette tape. The display indicates
which side is currently selected (
~º indi-
cates top side, !º indicates bottom side).
Auto-reverse feature: After the cassette
player reaches the end of a tape side, it automatically reverses and begins to play
the other side. This is ture whether the
cassette was playing or fast forwarding.
PWR/VOL (Power/Volume) Push PWR/VOLº to turn the audio sys-
tem on and off. Turn PWR/VOLº to adjust
the volume. RAND (Random)

(ETR). Push and release the  ~º (up) or
 ! º (down) side of TUNEº to set up or
down the station band. (If you hear a
beep, you held the button too long and the
radio willgo into the seek mode.) Seeking
In the seek mode, the radio finds and plays the next station up or down the sta- tion band.
To seek a station, push and hold the  ~º or
vº side of TUNEº until you hear a beep. Do this again to find another station. The anti-theft system prevents the audio
system f
rom working after it has been dis-
connected. To activate the system, you
must set a three-digit security code. After the system is set, SECº will appear in the
display each time the ignition is turned
form LOCKº to ACCº or ONº. Also, the
anti-theft light flashes every few seconds
while the ignition key is in the LOCKºposition.
You will need to know your security code
to reactivate your radio after electrical ser-vice is performed on your vehicle.
Choose a security code that is easy to re-
member and keep a copy of it (not in your
Toyota).

ILLUMINATION CONTROL LOGIC
On some audio-units, when the instru-
ment panel lights are on, the letters on op-
erable buttons of the mode in current use
light up together with the mode selectionand eject buttons. RADIO RECEPTION
Usually, a problem with radio reception
does not mean there is a problem with
your radioÐit is just the normal result of
conditions outside the vehicle.
For example, nearby buildings and terrain
can interfere with FM reception. Power
lines or telephone wires can interfere with
AM signals. And of course, radio signals
have a limited range, and the farther you are from a station, the weaker its signal
will be. In addition, reception conditions
change constantly as your vehicle moves. Here are some common reception prob-lems
that probably do not indicate a prob-
lem with your radio: FM
Fading and driving stationsÐGenerally,
the effective range of FM is about 40 km
(25 miles). Once outside this range, you
may notice fading and drifting, which in- crease with the distance from the radio
transmitter. They are often accompanied by distortion.
Multi-pathÐFM signals are reflective,
making it possible for two signals to reach
your antenna at the same time. If this hap-
pens, the signals will cancel each other
out, causing a momentary flutter or loss of
reception.
Static and flutteringÐThese occur when
signals are blocked by buildings, trees, or other large objects. Increasing the bass
level may reduce static and fluttering.
Station swappingÐIf the FM signal you are listening to is interrupted or weak-
ened, and there is another strong station
nearby on the FM band, your radio may
tune in the second station until the original
signal can be picked up again. AM FadingÐAM broadcasts are reflected by the upper atmosphere-especially atnight. These reflected signals can inter-
fere with those received directly from the radio station, causing the radio station tosound alternately strong and weak.
Station interferenceÐWhen a reflected
signal and a signal received directly from a radio station are very nearly the same
frequency, they can interfere with each
other,
making it difficult to hear the broad-
cast.
StaticÐAM is easily affected by external sources of electrical noise, such as high
tension power lines, lightening, or electri-cal motors. This results in static.
CARING FOR YOUR CASSETTE PLAY-
ER AND TAPES
For high performance from your cassette
player and tapes:
Clean the tape head and other parts regu-
larly. A dirty tape head or tape path can de-
crease sound quality and tangle your
cassette tapes. The easiest way to
clean them is by using a cleaning tape.
(A wet type is recommended.)
