Precautions
•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 being 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
two-speaker system, set the fader control to
the centre position.
•When a tape is played back for a long period,
the cassette may become warm because of
the built-in power amplifier. However, this is
not a sign of malfunction.
If you have any questions or problems
concerning your unit that are not covered in
this manual, please consult your nearest Sony
dealer.
To maintain high quality sound
If you have drink holders near your audio
equipment, be careful not to splash juice or
other soft drinks onto the car audio. Sugary
residues on this unit or cassette tapes may
contaminate the playback heads, reduce the
sound quality, or prevent sound reproduction
altogether.
Cassette cleaning kits cannot remove sugar
from the tape heads.
Welcome !
Thank you for purchasing this Sony Cassette
Player.
In addition to the cassette playback and radio
operations, you can expand your system by
connecting an optional CD/MD unit*1.
When you operate this unit or a connected
optional CD unit with the CD TEXT function,
the CD TEXT information will appear in the
display when you play a CD TEXT disc*2.
*1You can connect a CD changer, an MD changer,
a CD player, or an MD player.
*2A CD TEXT disc is an audio CD that includes
information such as the disc name, artist name,
and track names.
This information is recorded on the disc.

Notes on Cassettes
Cassette care
•Do not touch the tape surface of a cassette, as
any dirt or dust will contaminate the heads.
•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.
•Slack in the tape may cause the tape to be
caught in the machine. Before you insert the
tape, use a pencil or similar object to turn the
reel and take up any slack.
•Distorted cassettes and loose labels can cause
problems when inserting or ejecting tapes.
Remove or replace loose labels.
•The sound may become distorted while
playing the cassette. The cassette player head
should be cleaned after each 50 hours of use.
Slack
Cassettes longer than 90 minutes
The use of cassettes longer than 90 minutes is
not recommended except for long continuous
play. The tape used for these cassettes is very
thin and tends to stretch easily. Frequent
playing and stopping of these tapes may cause
them to become entangled in the cassette deck
mechanism.

¡Bienvenido! Precauciones
•Si aparca el automóvil bajo la luz solar
directa y se produce un considerable
aumento de temperatura en su interior, deje
que la unidad se enfríe antes de utilizarla.
•Si la unidad no recibe alimentación,
compruebe las conexiones en primer lugar. Si
todo estáen orden, examine el fusible.
•Si los altavoces no emiten sonido con un
sistema de dos altavoces, ajuste el control de
equilibrio en la posición central.
•Si reproduce la cinta durante mucho tiempo,
el cassette puede calentarse debido al
amplificador de potencia incorporado. No
obstante, esto es normal.
Si desea realizar alguna consulta o solucionar
algún problema referentes a la unidad que no
se mencionen en este manual, póngase en
contacto con el proveedor Sony más próximo.
Para mantener una alta calidad de
sonido
Si existen soportes para bebidas cerca del
equipo de audio, tenga cuidado de que no
salpiquen zumos u otras bebidas dulces sobre
el mismo, ya que la existencia de residuos
azucarados en la unidad o en las cintas de
cassette pueden ensuciar los cabezales de
reproducción, reducir la calidad del sonido o
eliminar el sonido de reproducción.
Los kits de limpieza para cassettes no eliminan
las sustancias azucaradas de los cabezales de
cinta.
