CARE AND MAINTENANCE

Head Cleaning

If the heads are not cleaned for a long period, dirt or

dust may be deposited on the heads and capstans,

causing degraded high-frequency characteristics,

volume drop, or degraded recording and erasure

performances. To prevent this, clean the heads,

capstans, etc., periodically as follows.

1. Turn the power off.

2. Open the cassette holder by pressing the EJECT

button.

3. As shown, clean the parts which come in contact

with tape, including the heads, capstans, tape guides,

pinch wheels, etc., with a cotton swab soaked in head

cleaning solution.

Head Demagnetization

When a magnetized metallic object (such as a

screwdriver tip) comes in contact with a head or

capstan, or when the deck has been used for a long

period of time, the head may be magnetized and

noise may be generated. If the head is extremely

magnetized, the high frequencies in recorded tapes

could even be erased. To prevent this, demagnetize

the heads and capstans periodically (every 20 hours

of use) using a commercially available head demag-

netizer. (For this operation, please refer to the instruc-

tion manual supplied with your head demagnetizer.)

Caution: Be sure to turn the power of the cassette

deck off before using a head demagnetizer.

CLEANING EXTERIOR SURFACES

The exterior finish of your unit will last indefinitely with

proper care and cleaning. Never use scouring pads,

steel wool, scouring powders or harsh chemical

agents (e.g., lye solution), alcohol, thinners, benzene,

insecticide or other volatile substances, as these will

mar the finish of the equipment. Likewise, never use

cloths containing chemical substances. If the equip-

ment gets dirty, wipe the external surfaces with a soft,

lint-free cloth.

If the equipment becomes heavily soiled:

• dilute some liquid soap in water, in a ratio of one

part detergent to six parts water

• dip a soft, lint free cloth in the solution and wring

the cloth out until it is damp

• wipe the equipment with the damp cloth

• dry the equipment by wiping it with a dry cloth.

COMPACT DISCS

The glossy side (shining like a rainbow) is the front

side of the disc; and; the side on which the label is

printed is the back. Unlike conventional turntables for

playing analog discs, compact disc players read the

information recorded on the disc from underneath

without contacting it, using a beam of laser light.

Therefore, the performance of a compact disc will not

degrade like conventional analog records.

Handle discs carefully so as not to damage or scratch

the front side.

To protect the disc, avoid placing it in the following

locations:

• In direct sunlight or near a source of heat like a

heater.

• In a place which is damp or dirty.

• In a place which could be exposed to rain, such

as near a window.

Always keep the disc surface clean.

Up to six billion data units are recorded on the front

side of the disc. When cleaning the disc surface,

always be sure to use a special compact disc cleaner

and wipe as shown below.

Wipe in a radial

direction.

Do not wipe in circumfer-

ential direction.

Do not use conventional record cleaner for analog

records, as this will adversely affect the disc surface.

Store discs properly by placing them in their disc

cases.
