CAUTION: READ THIS BEFORE OPERATING

YOUR UNIT.

1. This unit is a sophisticated stereo cassette deck. To ensure

proper operation for the best possible performance, please

read this manual carefully.

2. Choose the installation location of your unit carefully. Avoid

placing it in direct sunlight or close to source of heat. Also

avoid locations subject to vibration and excessive dust, heat,

cold or moisture. Keep it away from sources of hum such as

transformers or motors.

3. Do not open the cabinet as this may result in damage to the

deck or electrical shock. If a foreign object should get into

the deck, contact your local dealer.

4. When removing the power plug from the wall outlet, always

pull directly on the plug; never pull the cord itself.

5. Do not apply excessive force when operating switches and

knobs.

6. When moving the deck, be sure to first pull out the power

plug and remove all cords connecting the deck to other

equipment.

7. Do not attempt to clean this unit with chemical solvents as

this may damage the finish. Use a clean, dry cloth.

8. Never allow metallic items (e.g. screwdrivers, tools, etc.) to

come near the record/playback head assembly. Doing so

may not only scratch or damage the head’s mirror-smooth

finish, it may also change the magnetic characteristics of the

heads, causing a deterioration in reproduction quality.

9. Although the record/playback head used in this unit is a high

quality head with outstanding reproduction characteristics, it

can become dirty through the use of old tapes or from dust

accumulation over time. This can have a serious effect on

reproduction quality. Clean the heads regularly with one of

the commonly available head cleaners or with cleaning

solutions as explained later in this manual.

10. Be sure to read the “TROUBLESHOOTING” section of this

manual for advice on common operating errors before

concluding that your unit is faulty.

11. Keep this manual in a safe place for future reference.

12. Voltage Selector (General model only)

The voltage selector on the rear panel of this unit must

be set for your local mains voltage BEFORE plugging in

the AC mains supply. (Voltage selector adjustable

between 110/120/220/240 V AC.)

PROTECTING YOUR RECORDINGS

All cassette tapes are provided with erasure protection holes

to prevent accidental erasure of recorded contents. There is

a small tab covering the hole on each side of the cassette,

and it should be broken off after recording the tape. Without

this tab covering the hole, it is impossible to record onto that

tape. Thus, you can safely protect a recording for as long as

you wish without fear of accidental erasure. Should you wish

to use a cassette tape protected in this way for recording,

simply covering the hole with adhesive tape will permit

erasure and re-recording.

÷ When using Chrome (Type II/HIGH <CrO

2>) or Metal

(Type IV/METAL) tapes, make sure you do not cover the

hole intended for the Auto Tape Selector operation.

TAKING UP SLACK IN THE TAPE

As a precaution against tape entanglement and damage,

remove any slack in the tape before inserting cassettes into

the deck. This is accomplished by inserting a pencil, pen or

similar object into one of the spools and gently winding it

until all the slack is removed. You do not have to wind it too

tightly.

Be careful not to touch the tape part itself. It is very delicate

and touching it may damage the tape and its recorded

contents.

STORING CASSETTES

After putting a cassette tape back into its case, store it in a

location away from exposure to direct sunlight, humidity,

high temperatures, and magnetic fields (away from television

sets, speakers, etc.). High temperatures and humidity will

damage the tape itself, while exposure to magnetic fields

may cause a loss of recorded material. Avoid touching the

tape surface with your fingers, since dirt or finger oil will

contaminate the deck’s heads.

CASSETTE TAPES

There are many different types of cassette tapes available.

However, they all conform to standard specifications so any

brand may be used with the deck.

÷ Classification of Cassette Tapes by Formulation:

Cassette tapes are available in four basic types depending

on their formulation, or type of magnetic material and

manufacturing process. These four types are commonly

known as Normal (Type I/NORM), Chrome (Type II/HIGH

<CrO

2>), Ferrichrome (Type III/FeCr), and Metal (Type IV/

METAL), and they each require specific tape deck

adjustments for optimum performance.

* YAMAHA does not recommend the use of 120 minute

length cassettes since the extreme thinness of the tape

makes them susceptible to mechanical and recording

problems.

AUTO TAPE SELECTOR DETECTION SLOTS

The deck has a built-in Auto Tape Selector which

automatically adjusts for the proper bias, level and

equalization according to the tape formulation — all you

have to do is to load a cassette and the Auto Tape Selector

does the rest.

The Auto Tape Selector determines which type of tape is

loaded by sensing detector slots in the top of the tape shell.

Each tape formulation has its own characteristic hole

markings standardized by the tape industry.

÷ Early model Metal (Type IV/Metal) tape formulation

cassette shells do not have the slots for Auto Tape

Selector operation. As a result, early model Metal type

tapes recorded on another deck will be played back with

the deck at the Chrome (Type II/HIGH <CrO

2>) settings.

YAMAHA does not recommend using this kind of tape.

÷ The deck does not have the required setting for

Ferrichrome (Type III/FeCr) tape, since this tape

formulation is not widely used. Should you use a

Ferrichrome tape, it will be recorded and played back at

the Normal (Type I/NORM) settings, which will result in an

unnatural high frequency emphasis. This effect may be

compensated for somewhat by adjusting the tone controls

of your amplifier/receiver during playback.

operate this unit at your listening position. For details, refer

to the instruction manual supplied with the remote control

transmitter.

REMOTE CONTROL OPERATION RANGE

MAINTENANCE

CLEANING OF THE TAPE PATH

Continued high quality performance of your deck is

dependent upon periodic cleaning of the heads, capstan,

pinch roller, and all surfaces over which the tape travels.

Normal use will cause an accumulation of dirt and dust on

the heads, capstans, and pinch rollers. This can lead to

poor sound quality, drop outs (intervals with no sound),

unsteady tape speed, loss of high frequency response, etc.

Thus, clean the heads and all surfaces over which the tape

travels with a commercially available cleaning cassette and

fluid type cleaner.

DEMAGNETIZATION

After 20-30 hours of use, enough residual magnetism will

build up on the heads to cause poor high frequency

reproduction. At this time you should use a commercially

available cassette tape-type head demagnetizer.

÷ When cleaning the tape path or demagnetizing the heads,

be sure to follow carefully the instructions of the

concerning materials such as cleaning fluid or head

demagnetizer.
