Thank you for purchasing this YAMAHA stereo cassette deck.
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
NOTE:
Please check the copyright laws in your country to
record from records, compact discs, radio, etc.
Recording of copyright material may infringe
copyright laws.
WARNING
TO REDUCE THE RISK OF FIRE OR ELECTRIC
SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN
OR MOISTURE.
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.
This unit is not disconnected from the AC power
source as long as it is connected to the wall outlet,
even if this unit itself is turned off. This state is called
the standby mode. In this state, this unit is designed
to consume a very small quantity of power.
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 equipments.
7. Do not attempt to clean this unit with chemical
solvents as this may damage the finish. Use a clean,
dry cloth.
For U.K. customers
If the socket outlets in the home are not suitable for the
plug supplied with this appliance, it should be cut off and
an appropriate 3 pin plug fitted. For details, refer to the
instructions described below.
Note: The plug severed from the mains lead must be
destroyed, as a plug with bared flexible cord is hazardous
if engaged in a live socket outlet.
IMPORTANT
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, but 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
THE WIRES IN MAINS LEAD ARE COLOURED IN
ACCORDANCE WITH THE FOLLOWING CODE:
Blue: NEUTRAL
Brown: LIVE
As the colours of the wires in the mains lead of this
apparatus may not correspond with the coloured
markings identifying the terminals in your plug,
proceed as follows: The wire which is coloured BLUE
must be connected to the terminal which is marked
with the letter N or coloured BLACK. The wire which is
coloured BROWN must be connected to the terminal
which is marked with the letter L or coloured RED.
Making sure that neither core is connected to the
earth terminal of the three pin plug.
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.

÷ MPX filter:
FM stations transmit a 19 kHz pilot signal in addition to
the broadcast program. Sometimes this pilot signal
may leak into the audio output depending on the tuner
and broadcast conditions. This signal can cause
improper operation of the Dolby NR systems.
Activating the MPX filter (B TYPE/C TYPE MPX ON
settings) will effectively remove the signal.
To clear Auto Tape Tuning setting, press the AUTO TAPE
TUNING button once again, or load any cassette tape of
different type.
* When recording on the other side of the tape, another
Auto Tape Tuning is unnecessary.
When recording on the same type cassette tape of a
different brand, another Auto Tape Tuning is advisable
for much more accurate setting of the recording
characteristics.
AUTO TAPE TUNING
The Auto Tape Tuning function improves the quality of
your recording, permitting critical adjustment of the
deck’s recording bias and sensitivity for best results
with every tape you use.
With the Auto Tape Tuning function, the recording
characteristics (recording bias and sensitivity) are
automatically adjusted while recording and playback
operations in about 20 seconds, to accurately match
the characteristics of loaded tape.
For example, the recorded (output) level (A in the
figure) may differ from recording (input) level (B in the
figure), due to widely varying characteristics of
cassette tapes between brands.
Using the Auto Tape Tuning function, these differences
are effectively eliminated by adjusting the recording
bias (for high frequencies) and sensitivity (for overall
frequencies) according to the loaded cassette tape,
making a significant contribution to overall recording
quality (C in the figure).
Pressing this button during the REC/PAUSE mode will
activate the Auto Tape Tuning that makes it possible to
internally determine the optimum recording characteristics
(bias and recording sensitivity) according to the loaded
cassette tape in about 20 seconds.
To perform the Auto Tape Tuning, send the tape leader
part forward and set the PLAY/TRIM control and the BIAS
ADJUST control to the center position before pressing the
AUTO TAPE TUNING button. When the Auto Tape Tuning
is completed, the TAPE TUNING indicator lights. After
completion of Auto Tape Tuning, the tape automatically
rewinds to the point where the Auto Tape Tuning began
and the REC/PAUSE mode is engaged. The bias
adjustment with the BIAS ADJUST control is possible
even after this tuning.

Bias adjustment
The BIAS ADJUST control is for fine adjustment of the
recording bias. Normally, it is not necessary to adjust this
control since the recording bias can be automatically
adjusted by the built-in Auto Tape Selector and the AUTO
TAPE TUNING button for different tape types.
However, if you feel that your recording needs further bias
adjustment (to compensate for absent or distorted high
frequencies), adjust this control to your liking.
When high frequencies are
distorted, increase the
recording bias by turning
the BIAS ADJUST control
clockwise.
When high frequencies are
absent, decrease the recording
bias by turning the BIAS
ADJUST control
counterclockwise.

Remember to set the proper recording level.
2. Set the timer to the desired recording start and stop
times. It is advisable to set the timer to begin recording
slightly before and end slightly after the actual
broadcast receiving time to leave some room for later
editing.
3. Set the TIMER switch to the REC position.
1. Turn on the amplifier/receiver and adjust the volume
and tone controls.
2. Set the input mode selector of your amplifier/receiver to
the cassette deck function mode.
3. Set the timer to the time you wish to start and stop
playback.
4. Set the TIMER switch to the PLAY position.

4. The timer will send power to the amplifier/receiver,

components on and initiating the recording.

5. At the preset time, the timer will turn power on to the
amplifier/receiver and cassette deck and begin
playback. It will shut power off at the preset time as
well ending playback.
Note: Whenever the timer recording/playback is not
intended, make sure to set the TIMER switch to OFF
position to prevent the unnecessary recording/playback.
÷ If the TIMER switch is set to REC position and the
power is supplied (plugging in the power cord or
automatically supplying the power after power failure,
etc.), the deck automatically enters Rec mode and the
contents of the cassette tape inserted in the deck will
be erased.
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 <CrO2>), 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 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 <CrO2>)
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
BIAS ADJUST to the plus (+) direction during
recording, or by using the PLAY TRIM control and/or
the tone controls of your amplifier/receiver during
playback.
TYPE II
Detector slots
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 rerecording.
÷ When using Chrome (Type II/HIGH <CrO2>) 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.
TYPE IV
Detector slots
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.

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.
Inside of the cassette compartment
Heads
Capstan
Pinch roller
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 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.
