Precautions
e If your car was parked in direct sunlight resulting in a considerable
rise in temperature inside the car, allow the unit to cool off before
operating it.
¢ If no power is supplied to the unit, check the connections first. If
everything is in order, check the fuse.
¢ If no sound comes from the speakers of a 2-speaker system, set
the fader control to the center position.
If you have any questions or problems concerning your unit that are
not covered in this manual, please consult your nearest Sony

Notes on Cassettes
Cassette care
¢ Avoid touching the tape surface of a cassette, as any dirt or dust
will contaminate the heads.
e Keep cassettes away from equipment with built-in magnets such
as speakers and amplifiers, as erasure or distortion on the
recorded tape could occur.
Do not expose cassettes to direct sunlight, extremely cold
temperatures or moisture.
¢ When the tape is played back for a long time, the cassette shell
may become warm because of the built-in power amplifier.
However, this is not a sign of a malfunction.
Notes on Cassettes longer than 90 minutes
The use of cassettes longer than 90 minutes is not recommended
except for tong continuous play. The tapes used for these cassettes
are very thin and tend to be stretched easily. Frequent playing and
stopping operation may cause these tapes to be pulled into the
cassette deck mechanism.
Notes on the Front Panel
e When you detach the front panel, turn off the power to the unit.
However, if you detach the front panel while the unit is turned on,
the power will automatically be turned off. This will protect
speakers from being damaged.
e Do not expose the front panel to direct sunlight, heat sources such
as hot air-ducts, extremely cold temperatures or moisture.

The BTM function
The BTM function searches all the receivable stations
within the currently selected band and memorizes the ones
in good receiving conditions in sequence from the lowest
frequency.
How to memorize the stations on the preset number
buttons
— When there is no preset number indicated on the display window:
all the preset number buttons set in the currently selected band
will be filled with the memories.
—— When there is a preset number indicated on the display window:
the unit will memorize the stations on the preset number buttons
from the one currently being displayed. For example, when you
choose FMI and preset number 3 is being displayed, the
operation will start from the preset number 3 on FMI and stops at
the preset number 6 on FMIII.
Stations with clearest
reception are automatically
searched and memorized
on each band (FMI, FMII,
FMiIl and AMI, AMII). Up
to 6 stations on each band
can be stored on the
preset number buttons 1 to
6 in the order of frequency.
The receivable frequencies of
FMI, FMII and FMIII are the
same.
Therefore, 18 stations can be
memorized on FM.
Note
There may be cases where
there are not enough receivable
stations due to the lack of
stations in the vicinity or weak
broadcasting signals. In such
cases, the BTM operation may
stop without all the buttons being
occupied with memories.

Memorizing Only the Desired Stations
Up to 6 stations on each
band (FMI, FMI], FMI
and AMI, AMII) can be
stored in the memory in
order of your choice.
For example, store a station on the preset number button 1.
Select the desired band. Only one station per band
(FMI, FMII, FMIII and AMI,
[Fuvam| AMII) can be stored in the
memory on each preset
number button.
