To clean the head
• Clean the heads after every 10 hours of use
using a wet-type head cleaning tape (available
at an audio store).
When the head becomes dirty, you may
realize the following symptoms:
– Sound quality is reduced.
– Sound level decreases.
– Sound drops out.
• Do not touch the highly-polished head with
any metallic or magnetic tools.
To keep the tape clean
• Always store the cassettes in their storage
cases after use.
• Do not store cassettes in the following places:
– Subject to direct sunlight
– With high humidity
– At extremely hot temperatures
Handling discs
Moisture condensation
Moisture may condense on the lens inside the
CD player in the following cases:
• After starting the heater in the car.
• If it becomes very humid inside the car.
Should this occur, the CD player may
malfunction. In this case, eject the disc and
leave the unit turned on for a few hours until the
moisture evaporates.
How to handle discs
When removing a disc from
its case, press down the center
holder of the case and lift the
disc out, holding it by the edges.
• Always hold the disc by the
edges. Do not touch its recording surface.
When storing a disc into its case, gently insert
the disc around the center holder (with the
printed surface facing up).
• Make sure to store discs into the cases after
use.
To keep discs clean
A dirty disc may not play correctly.
If a disc does become dirty, wipe
it with a soft cloth in a straight line
from center to edge.
• Do not use any solvent (for example,
conventional record cleaner, spray, thinner,
benzine, etc.) to clean discs.
To play new discs
New discs may have some rough
spots around the inner and outer
edges. If such a disc is used, this
unit may reject the disc.
To remove these rough spots, rub the edges
with a pencil or ball-point pen, etc.
