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 of 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  
period, the cassette shell may become warm  
because of the built-in power amplifier. This  
is not a sign of a malfunction.

Notes on Cassette Deck Tape Heads  
Long use of cassette tapes contaminates the  
tape head causing poor sound quality or  
complete sound dropout. Therefore, we  
recommend cleaning the tape head once a  
month or so with the separately available  
Sony Cassette Cleaning Set. If the sound does  
not improve after using a cleaning cassette,  
please consult your nearest Sony dealer.  
In case of old or inferior cassette tapes, the  
tape head gets contaminated much more  
quickly. Depending on the tape, one or two  
playbacks may cause poor sound.

Cassettes longer than 90 minutes  
The use of cassettes longer than 90 minutes is  
not recommended except for long continuous  
play. The tapes used for these cassettes are  
very thin and tend to be stretched easily.  
Frequent playing and stopping of these tapes  
may cause them to be pulled into the cassette  
deck mechanism.

Notes  
Make sure that the front panel is the right way up when  
attaching it to the unit as it cannot be attached upside  
down.  
Do not press the front panel hard against the unit when  
attaching it to the unit. It can easily be attached by  
pressing it lightly against the unit.  
Do not press hard or give excessive pressure to the  
display windows of the front panel.  
Before removing the front panel, be sure to turn the  
power off. However, if you press the RELEASE button to  
detach the panel while the unit is still turned on, the  
power will be automatically turned off in order to protect  
the speakers from being damaged.  
Do not expose the front panel to direct sunlight, heat  
sources such as hot air ducts or leave it in a humid place.  
Never leave it on the dashboard etc. of a car parked in  
direct sunlight where there may be a considerable rise in  
temperature inside the car.
