Maintenance
To clean the tape heads and tape
path
Contaminated tape heads cause poor
recording or sound dropout in playback.
We recommend cleaning after every 10
hours of operation.
Open the cassette holder and wipe the
heads, pinch rollers and capstans with a
cleaning swab slightly moistened with
cleaning fluid or alcohol. Wipe the parts
shown below:

Turn MIC LEVEL to MIN.
➔
Move the microphone away from
the speakers or change the direction
of the microphone.
Insert a tape after the areas cleaned are
completely dry.
To demagnetize the tape heads
After 20 to 30 hours of use, enough residual
magnetism will have built up on the heads
to begin to cause loss of high frequencies
and hiss. At this time, demagnetize the
heads and all metal parts in the tape path
with a commercially available tape head
demagnetizer. Refer to the instructions of
the demagnetizer.
To clean the cabinet
Use a soft cloth slightly moistened with a
mild detergent solution.
To clean the CD
When a CD is dirty, clean it with a cleaning
cloth. Wipe the CD from the centre out.
Notes on CDs
•
Do not use solvents such as benzene,

or antistatic spray intended for vinyl LPs.
•
If there is a scratch, dirt or fingerprints on
the CD, it may cause a tracking error.
