Troubleshooting
If your unit fails to perform properly, check the following guide
and the relevant sections of the Operating Instructions.
First check that the AC power cord and the speakers are
connected correctly and firmly.
Should any problem persist, consult your nearest Aiwa dealer.
General
There is no sound
•Are the speakers and AC power cord connected properly?
•Turn VOLUME clockwise and hold.
•The headphones are connected.
•Insert only the stripped portion on the speaker cord into the
SPEAKERS terminal. Inserting the vinyl portion of the
speaker cord will obstruct the speaker connections.

•Possibly a short circuit in the speaker terminals. Disconnect
the AC power cord from the AC power socket and reconnect
the speaker cords correctly.
The display blacks out when the unit is turned off.
•Is ECO mode set to on? (see "ECO mode" on page 7)
Erroneous display
•Reset the unit. (See "Resetting the unit" on page 19)
There is severe hum or noise.
•A TV or VCR is placed too close to the stereo system. Move
the stereo system away from the TV or VCR.
The clock indication does not show the correct time.
•A power interruption occurred. Set the clock and timer
settings again.
The clock setting/radio presetting/timer is cancelled.
•The AC power cord is disconnected or a power failure occurs
longer than half a day.
Redo the following:
- "Setting the clock" on page 7
- "Preset tuning" on page 10
If you have set the timer, also redo "Timer playback/
recording" on page 16 and 17.
The timer does not function.
•Set the clock correctly.
The remote does not function.
•There is an obstacle between the remote and the unit.
•The remote is not pointing in the direction of the unit's
sensor.
•The batteries have run down. Replace the batteries.

appliances and cords.
Care and maintenance
Occasional care and maintenance of the unit and the software
are needed to optimize the performance of your unit.
To clean the cabinet
Use a soft and dry cloth. If the unit surfaces are extremely
dirty, use a soft cloth lightly moistened with mild detergent
solution. Do not use strong solvents such as alcohol, benzine
or thinner.
To clean the tape heads
Dirty tape heads cause sound deterioration. After every 10
hours of use, clean the tape heads by using a commercially
available dry-type or wet-type head cleaning cassette
separately. Refer to the instructions of the cleaning cassette.
To demagnetize the tape heads
Use a demagnetizing cassette after every 20 to 30 hours of
use. Refer to the instructions of the demagnetizing cassette.
Care of CDs
When a CD becomes dirty, wipe it from the centre out with a
cleaning cloth. Please, do not use solvents. After playing a
CD, store it in its case. Do not expose a CD to direct sunlight
or heat sources.
Care of tapes
Store tapes in their cases after use. Do not leave tapes near
magnets, motors, television sets, or any source of magnetism.
Do not expose tapes to direct sunlight, or leave them in a car
parked in direct sunlight.
