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.

Do not apply excessive force when operating switches and knobs.

5.

When moving the deck, be sure to first pull out the power plug and
remove all cords connecting the deck to other equipment.

6.

Do not attempt to clean this unit with chemical solvents as this may
damage the finish. Use a clean, dry cloth.

7.

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.

8.

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.

9.

Be sure to read the “Troubleshooting” section of this manual for
advice on common operating errors before concluding that your unit
is faulty.

10.

Unplug the power cord from the wall outlet if the unit is not to be
used for an extended period of time. To disconnect the cord, pull it
out by grasping the plug. Never pull the cord itself.

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.

distortion – and, most importantly, without
affecting your sensitive hearing.  Since
hearing damage from loud sounds is often
undetectable until it is too late, YAMAHA and
the Electronic Industries Association's
Consumer Electronics Group recommend
you avoid prolonged exposure to excessive
volume levels.
