The heads, capstan and pinch roller are parts which are liable

to become dirty quite easily, In particular, if the heads are dirty,

the high frequency components of the sound will not be

reproduced and the stereo balance will be impaired, resulting

ina deterioration of sound quality. tis therefore recommended

that the head section be cleaned regularly.

1. Turn the power off.

2. Press EJECT & to open the cassette door.

3. Dip a cleaning swab into head cleaning fluid and use it to

wipe the head, capstan, and pinch rollers. Wait 2-3 minutes

until the cleaning fluid dnes.

This unit uses a head-slant standby system, with the result

that the heads are mounted at an angled position.

Selecting fine audio equipment such as the unit you've just

purchased is only the start of your musical enjoyment, Now it's

time to consider how you can maximize the fun and excitement

your equipment offers, This manufacturer and the Electronic

Industries Association's Consumer Electronics Group want you

to get the most out of your equipment by playing it at a safe

jevel, One that lets the sound come through Joud and clear

without annoying blaring or distortion-and, most importantly,

without affecting your sensitive hearing.

Sound can be deceiving. Over time your hearing "comfort

level" adapts to higher volumes of sound. So what sounds

"normal" can actually be loud and harmful to your hearing.

Guard against this by setting your equipment ai a safe level

BEFORE your hearing adapts.

To establish a safe level:

@ Start your volume control at 4 low setting.

® Slowly increase the sound until you can hear it corefortably

and clearly, and without distortion.

Once you have established a comfortable sound level:

@ Set the dial and leave it there.

Taking 4 minute to do this now will help to prevent hearing

damage or loss in the future. After all, we want you listentag for

a lifetime.

The deck heads may become magnetized after the deck has

been used for a long period of time, or if a magnet or other

magnetized

object (screwdriver,

etc.) is brought near the

heads. Magnetization of the heads results in increased noise

and reduced ability to reproduce high-frequency sounds.

In this case,

please use

a commercially

available

head

demagnetizer at regular intervals to eliminate the magnetic

field onthe heads. When using a head demagnetizer, turn this

unit's power switch ON. In order to prevent adverse effects

on the receiver and speakers, however, be sureto turn down

the receiver's volume control to its lowest position, and

disconnect any headphones from their headphones jack, For

details, consult the instructions accompanying

your head

demagnetizer.

Use a polishing cloth or dry cloth to wipe off dust and dirt.

@ When the surfaces are very dirty, wipe with a soft cloth

dipped in sorne neutral cleanser diluted five or six times

with water and wrung out well, then wipe again with a dry

cloth. Do not use furniture wax or cleaners.

Never use thinners, benzene, insecticide sprays or other

chemicals on or near this unit, since these will corrode the

surfaces.

Used wisely, your new sound equipment will provide a

lifetime of fun and enjoyment. Since hearing damage from loud

noise is often undetectable until it is too late, this manufacturer

and the Electronic Industries Association's Consumer Electronics

Group recommend you avoid prolonged exposure to excessive

aise, This list of sound levels is included for your protection.
