7. Wall or Ceiling Mounting — The appliance should be mounted
to a wall or ceiling only as recommended by the manufacturer.
8. Ventilation — The appliance should be situated so that its
location or position does not interfere with its proper ventilation.
For example, the appliance should not be situated on a bed, sofa,
rug, or similar surface that may block the ventilation openings; or
if placed in a built-in installation, such as a book case or cabinet
that may impede the flow of air through the ventilation openings,
there should be free space of at least 20 cm (8 in.) and open up
behind the appliance.
9. Heat — The appliance should be situated away from heat sources
such as radiators, heat registers, stoves, or other appliances
(including amplifiers) that produce heat.
10. Power Sources — The appliance should be connected to a power
supply only of the type described in the operating instructions or as
marked on the appliance.
11. Polarization — If the appliace is provided with a polarized plug
having one blade wider than the other, please read the following
information: The polarization of the plug is a safety feature. The
polarized plug will only fit the outlet one way. If the plug does not
fit fully into the outlet, try reversing it. If there is still trouble, the
user should seek the services of a qualified electrician. Under no
circumstances should the user attempt to defeat the polarization of
the plug.
12. Power-Cord Protection — Power-supply cords should be routed
so that they are not likely to be walked on or pinched by items
placed upon or against them, paying particular attention to the cords
at plugs, convenience receptacles, and the point where they exit
from the appliance.

PORTABLE CART WARNING
S3125A
1. Warranty Card
The serial number is written on the rear panel of this unit.
(Write the serial number and model number onto your
warranty card and keep it in a safe place.)
2. Recording Copyright
Recording of copyrighted material for other than personal use
is illegal without permission of the copyright holder.
3. Deck Location
• Do not use or leave in direct sunlight or in other places
subject to high temperature and humidity. The unit should
also not be left in potentially hot places such as near heating
appliances. Excessive heat and moisture can lead to internal
damage and serious malfunctions (this also applies to
cassette tapes). The recommended ambient temperature
range is 5°C to 35°C.
• Avoid damp and dusty places and locations prone to
vibrations.
• Be extremely careful with the recording/playback heads.
Clean and demagnetize them regularly, but under no
circumstances should magnets or other metals be used
anywhere near the heads.
• This unit is extremely sensitive to magnetic fields, so do not
use near large speakers or other devices which generate
magnetic fields.
• Hum may even be induced by magnetic flux leakage from
the power transformer in certain amplifiers. Therefore, this
unit should also be kept clear of the amplifier.
• Do not remove the cabinet case. If any of the internal parts
are handled, there is a considerable danger of electric
shock.
4. Cassettes to Avoid:
• Cassettes with poorly formed cases that rattle during rewind
and fast forward.
• Low cost cassettes with no guide roller or pressure pad
spring should never be used for stereo.
• C-120 cassettes — because the tape and the coating are
extremely thin, distortion levels are high. Also, even a
slight stretching of the tape will make it susceptible to
being caught up in the pinch roller and capstan.
• Endless tapes, if used for a long period of time, can
overheat.
5. Power
WARNING
BEFORE PLUGGING IN THE UNIT FOR THE
FIRST TIME, READ THE FOLLOWING SECTION
CAREFULLY.
• Some models are designed for use only with the power
supply voltage of the region where they are sold.
European models: AC 230V, 50Hz
U.S.A. and Canadian models: AC 120V, 60Hz
Worldwide models: AC 120 and 220-230V
switchable, 50/60Hz
• Voltage Selector (Rear Panel)
Worldwide models are equipped with a voltage selector to
conform with local power supplies. Be sure to set this
switch to match the power supply in your area before
plugging in the unit. Models without a voltage selector can
only be used in areas where the power supply voltage is the
same as that of the unit.

Using the Auto Accubias System
zz
Auto Accubias is a system that allows you to automatically set the optimal recording bias and level for the tape being used.
To activate this system, simply press the AUTO ACCUBIAS button when the unit is in the recording-standby mode. While the system is
calculating the optimal settings (the ACCUBIAS SET indicator flashes), the tape is automatically fast forwarded and rewound, a test
signal is recorded on it and then played back. In the display, the flashing bias indicators move to the right and left, and stop at the 0
position. When the optimal bias and level settings have been set, the ACCUBIAS SET indicator stays lit and the tape is rewound to the
position where the setting was started.
Note:
Do not initiate the Auto Accubias function when the tape is near the end of the side.
Manually Adjusting the Recording Bias
Although the Auto Accubias system may be used to set the recording bias and level as explained above, you can adjust the recording bias
independently for the right and left channels when the unit is in recording-standby mode or simultaneously during recording.
Note:
The manually-set recording bias setting will be lost once the AUTO ACCUBIAS button is pressed.
To adjust the recording bias independently for the right and left channels
1. While holding down the REC button, press the PAUSE button.
2. Press ACCUBIAS knob.
The display mode changes to allow you to adjust the recording bias in the range of -7 to +7. The L CH indicator flashes to indicate
that you are adjusting for the left channel.
3. Turn the ACCUBIAS knob and press it when the flashing bias indicator (initially placed at the previously set position) has reached
the desired level.
The L CH indicator now stays lit to indicate that the recording bias for the left channel is now set. The R CH indicator flashes.
4. In the same way, set the recording bias for the right channel.
The normal peak level display will be restored.
Note:
To clear the recording bias setting, eject the tape.
To adjust the recording bias while recording
1. Press the ACCUBIAS knob while recording.
The display mode changes to allow you to adjust the recording bias in the range of -7 to +7. The L CH and R CH indicators now
flash alternately.
2. Turn the ACCUBIAS knob and release it when the flashing right and left bias indicators (initially placed at the previously set
position) have reached the desired level.
The normal peak level display mode will be restored approximately four seconds after you release the knob.

Making Good Sounding Recordings
Dolby Noise Reduction Systems
Dolby B NR is the system used in most cassette tape decks to reduce the background noise that is inherent in all cassette tapes. Dolby
Laboratories then developed an even more effective noise reduction system, Dolby C NR, in response to the demand for increasingly
better sound quality from cassette tapes.
Both Dolby noise reduction systems operate by boosting signals during recording that fall below a certain input level. Dolby B and C
NR operate on the higher portions of the frequency spectrum using what is called a "sliding band'' technique. This is because tape hiss is
most prominent during the quiet, high frequency portions of a recording. These same signals are then reduced back to their original
strength during playback, thereby reducing the background noise by the same amount. In order to operate only when necessary, the
Dolby NR system has a varying effect depending on the input level and frequency of the material being recorded.
Dolby C NR is capable of reducing tape hiss by 10dB more than Dolby B NR. In addition to its noise reduction function, Dolby C
NR has an anti-saturation network that lowers high input levels before recording them and returns the signals to their original strength
during playback. This raises the high-frequency saturation level of cassette tapes to allow you to record signals that would normally
cause distortion. This system raises the maximum output level of cassette tapes by more than 4dB at 10kHz.
The Dolby HX Pro System
Tape sensitivity is constantly changing as recordings are made due to the biasing effect of high frequency audio signals. Dolby HX Pro is
a system that compensates for these undesirable fluctuations during recording. It does not operate during playback, so cassettes recorded
with Dolby HX Pro can be played back on decks not equipped with the system.
Note:
Dolby HX Pro operates independently of Dolby B and C NR, and only during recording.
Setting the Proper Recording Level
The recording level has an important effect on the sound quality a tape will have when it is played back. A recording level that is too high
will cause distortion while one that is too low will lower the signal-to-noise ratio resulting in a tape with excessive "hiss noise.'' It is
particularly important to set the recording level correctly with cassette tapes since they have a much thinner magnetic coating than open
reel tapes. The thin coating gives the tape a comparatively low saturation level which can easily be surpassed if the recording level is set
too high.
The optimal recording level varies depending on the type of the tape being used. With this tapedeck, adjust the REC LEVEL knob so
the PEAK LEVEL indicator occasionally hits the “+6dB” line with “Metal” tapes and “+4dB” line with “Normal” or “High” position
tapes, respectively. It should be noted that the peak level may change from one track to another on some recording sources.
The recording level indicators feature a peak-hold function for the indicators from -10 dB through +10 dB. This can come in handy
when setting the recording level.

Erasure Prevention
Cassette tapes are constructed with erasure
prevention niches on the back edge that are
initially covered by break-off tabs.
1. If you wish to protect a recording from
accidental erasure, break off the tab(s)
of the appropriate side(s). It will no
longer be possible to use the recording
button with such a cassette.
2. If at some later date you wish to re-
record the cassette, simply cover the
openings with small pieces of cellophane tape.
Tape Slack
Slack in the tape (tape not stretched tightly)
can cause tangling around the pinch roller
and capstan and jam the mechanism.
Remove any tape slack with a pencil or
similar device as shown in the diagram.

Tapes which are Not
Recommended
1. C120 tapes
C120 tape is thin and therefore easily
broken. There is a possibility that tape
could get caught up by the pinch roller
or capstan.
2. Endless tapes
Do not use endless tapes.
Tape Storage
• Do not touch the tape surface.
• Do not put thick paper or cardboard
labels in the cassette holder.
• Do not put tapes near magnetic sources
(speakers, amplifiers, TVs, etc.). Your
important recording might be erased or
damaged.
• Do not expose cassettes to direct
sunlight.

Cassette Deck
Specifications
Maintenance
This deck requires no lubrication.
Head, Pinch Roller and Capstan Cleaning
Playback sound quality can be greatly diminished if magnetic
particles are allowed to accumulate on the recording or playback
heads. Be sure to clean the heads periodically, normally 2 or 3
times a month, to maintain your deck's original performance.
Dirty heads will cause:
• Poor sound quality (loss of high frequency response)
• Decreased volume
• Skipping
• Incomplete erasure of previous recordings
If the pinch rollers and capstan are dirty, the tape may become
tangled and damaged by wrapping around the pinch roller and
capstan.
To prevent these problems, clean the heads, pinch rollers and
capstans with a cotton swab dipped in cleaning fluid.
Demagnetizing
Residual magnetism builds up in the heads after the cassette deck
has been used for an extended period of time. This buildup
introduces noise and static into tapes and impairs high frequency
response. To prevent this, demagnetize the heads and the other
metal parts in the area (like the capstan shafts) once every 50
hours of use. Keep the deck power off while using the demagnetizer. Also place tapes far away from the work area.
