Note

RDS may not work properly if the station you
are tuned in is not transmitting the RDS signal
properly or if the signal is weak.

* Not all FM stations provide RDS service, nor

do they provide the same type of services. If
you are not familiar with the RDS system,
check with your local radio stations for details
on RDS services in your area.

On safety

• The unit is not disconnected from the mains as
long as it is connected to the AC outlet, even
if the unit itself has been turned off.

• Completel y disconnect the power cord (mains
lead) from the wall socket (mains) if it is not
going to be used for an extended period of
time. When unplugging the unit, always grip
the plug. Never pull the cord itself.

• Should any solid object or liquid get into the
system, unplug the system, and have it
checked by qualified personnel before
operating it again.

• AC power cord must be changed only at the
qualified service shop.

On placement

• Do not place the system in an inclined
position or in locations that are extremely hot,
cold, dusty, dirty, or humid or lacking
adequate ventilation, or subject to vibration,
direct sunlight or a bright light.

• Be careful when placing the unit or speakers
on surfaces that have been specially treated
(for example, with wax, oil, polish) as staining
or discoloration of the surface may result.

• If the system is brought directly from a cold to
a warm location or is placed in a very damp
room, moisture may condense on the lens
inside the unit, and cause the system to
malfunction. In this situation, remove the
disc, and leave the system turned on for about
an hour until the moisture evaporates.

On heat buildup

• Heat buildup on the unit during operation is
normal and is not a cause for alarm.

• Do not touch the cabinet if it has been used
continuously at a high volume because the
cabinet may have become hot.

• Do not obstruct the ventilation holes.

On the speaker system

This speaker system is not magnetically
shielded, and the picture on nearby TV sets may
become magnetically distor ted. In this situation,
turn off the TV, wait 15 to 30 minutes, and turn
it back on. If there is no improvement, move the
speakers far away from the TV.

Cleaning the cabinet

Clean this system with a soft cloth slightly
moistened with a mild detergent solution. Do
not use any type of abrasive pad, scouring
powder, or solvent, such as thinner, benzine, or
alcohol.

To prevent a tape from being
accidentally recorded over

Break off the tape’s overwrite protection tab
from side A or B as illustrated.

Break
off the
tape tab

To later reuse the tape for recording, cover the
broken tab with adhesive tape.

About a tape longer than 90 minutes

The use of the tape with more than 90 minutes
of play time is not recommended except for
long, continuous recording or playback.

Cleaning the tape heads

Use a dry- or wet-type cleaning tape (available
separately) after every 10 hours of use, before
you start an important recording, or after
playing an old tape. Failure to clean the tape
heads can cause degraded sound quality or an
inability of the unit to record or play tapes. For
details, refer to the instructions of the cleaning
tape.

Demagnetizing the tape heads

Use a demagnetizing tape (available separately)
after every 20 to 30 hours of use. Failure to
demagnetize the tape heads can cause an
increase in noise, a loss of high frequency
sound, and an inability to completely erase
tapes. For details, refer to the instructions of the
demagnetizing tape.
