direct sunlight.
On safety
The unit is not disconnected from the AC power source
(mains) as long as it is connected to the wall outlet,
even if the unit itself has been turned off.
Completely 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 a 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 CD player, 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 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
distorted. 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 (Except for the UK model)
Break off the cassette’s overwrite protection tab from side
A or B as illustrated.
Break off the cassette
tab
To later reuse the tape for recording, cover the broken tab
with adhesive tape.
About a tape longer than 90 minutes (Except
for the UK model)
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 (Except for the UK
model)
Use dry- or wet-type cleaning cassette (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 cassette.
Demagnetizing the tape heads (Except for the
UK model)
Use a demagnetizing cassette (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 cassette.
