Self-diagnosis Function
(When letters/numbers
appear in the display)
When the self-diagnosis function is activated to
prevent the recorder from malfunctioning, a five-
character service number (e.g., C 13 00) with a
combination of a letter and four numbers appears
in the front panel display. In this case, check the
following table.
Notes About This Recorder
On operation
• If the recorder is brought directly from a cold to
a warm location, or is placed in a very damp
room, moisture may condense on the lenses
inside the recorder. Should this occur, the
recorder may not operate properly. In this case,
remove the disc and leave the recorder turned on
for about half an hour until the moisture
evaporates.
• When you move the recorder, take out any discs.
If you don’t, the disc may be damaged.
On adjusting volume
Do not turn up the volume while listening to a
section with very low level inputs or no audio
signals. If you do, the speakers may be damaged
when a peak level section is played.
On cleaning
Clean the cabinet, panel, and controls 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 alcohol or
benzine.
On cleaning discs
Do not use a commercially available cleaning
disc. It may cause a malfunction.
Notes about the discs
• To keep the disc clean, handle the disc by its
edge. Do not touch the surface. Dust,
fingerprints, or scratches on the disc may cause
it to malfunction.
• Do not expose the disc to direct sunlight or heat
sources such as hot air ducts, or leave it in a car
parked in direct sunlight as the temperature may
rise considerably inside the car.
• After playing, store the disc in its case.
