Important safeguards
Precautions
1. Read Instructions — All the safety and operating instructions
1. Warranty Claim
should be read before the appliance is operated.
You can find the serial number on the rear panel of the unit. In
case of warranty claim, please report this number.
2. Retain Instructions — The safety and operating instructions should
be retained for future reference.
3. Heed Warnings — All warnings on the appliance and in the
operating instructions should be adhered to.
2. Recording Copyright
Recording of copyrighted material for other than personal use is
illegal without permission of the copyright holder.
4. Follow Instructions — All operating and use instructions should be
followed.
5. Water and Moisture — The appliance should not be used near
water — for example, near a bathtub, washbowl, kitchen sink,
laundry tub, in a wet basement, or near a swimming pool, and the
like.
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 vibra-
tions.
6. Carts and Stands — The appliance should be used only with a cart
or stand that is recommended by the manufacturer.
6A. An appliance and cart combination should be moved with care. Quick
stops, excessive force, and uneven surface may cause the appliance
and cart combination to overturn.
PORTABLE CART WARNING
• 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.
S3125A
• This unit is extremely sensitive to magnetic fields, so do not
use near large speakers or other devices which generate
magnetic fields.
7. Wall or Ceiling Mounting — The appliance should be mounted to a
wall or ceiling only as recommended by the manufacturer.
• 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.
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 bookcase 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.
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.
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.
• 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.
11. Polarization — If the appliance 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.
• Endless tapes, if used for a long period of time, can overheat.
5. Power
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.
WARNING
BEFORE PLUGGING IN THE UNIT FOR THE FIRST
TIME, READ THE FOLLOWING SECTION CARE-
FULLY.
• The voltage of the available power supply differs according
to country or region. Be sure that the power supply voltage of
the area where this unit will be used meets the required
voltage (e.g., AC230V 50Hz or AC120V 60Hz) written on
the rear panel.
13. Cleaning — The appliance should be cleaned only as recommended
by the manufacturer.
14. Nonuse Periods — The power cord of the appliance should be
unplugged from the outlet when left unused for a long period of time.
15. Object and Liquid Entry — Care should be taken so that objects do
not fall and liquids are not spilled into the enclosure through
openings.
• 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. (See page 4)
16. Damage Requiring Service — The appliance should be serviced by
qualified service personnel when:
A. The power-supply cord or the plug has been damaged; or
B. Objects have fallen, or liquid has been spilled into the appliance;
or
C. The appliance has been exposed to rain; or
D. The appliance does not appear to operate normally or exhibits a
marked change in performance; or
E. The appliance has been dropped, or the enclosure damaged.
17. Servicing — The user should not attempt to service the appliance
beyond that described in the operating instructions. All other
servicing should be referred to qualified service personnel.

Making good sound recordings
Dolby Noise Reduction System
Setting the Proper Recording Level
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 reductions 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 fre-
quency 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 10 dB more
than Dolby B NR. In addition to its noise reducing 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 4 dB at 10
kHz.
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 which 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 recording level indicators feature a peak-hold function for the
indicators from -6 dB through +6 dB. This can come in handy
when setting the recording level.
CD Synchro Recording System
Once the TA-RW244/144 is connected to a CD player bearing the
z mark (see page 12), press the s button of the CD player will
cause recording to start automatically on the TA-RW244/144.
1. Insert a cassette with the side to be recorded facing out.
2. Start the CD player.
3. Press the t button to place the unit in the recording standby
mode. Adjust the input level. When the recording level has
been set, stop the CD player.
4. Start the CD player again, and recording will begin simultane-
ously.
Notes:
1. Even if the CD player is stopped during recording, the cassette
deck will continue recording.
2. If the cassette deck is in the recording standby mode when the
CD is put in play, the deck will begin recording. When setting
recording levels, always start the CD first.

Loose tape 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.
A
Tapes not recommended
1. C-120 tapes
C-120 tape is thin and therefore easily
broken. There is a possibility that tape
could get caught on 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.

Head, Pinch Roller and Capstan Cleaning
Playback sound quality can be greatly diminished if magnetic
particles are allowed to accumulate on the recording/playback
head or playback head. Be sure to clean the head periodically,
normally 2 - 3 times a month, to maintain your deck’s original
performance. Dirty heads may cause:
Standard output level: 500 mV
(0 dB)
Optimum load impedance: over
50 kohms

TA-RW144:
• Poor sound quality (lose 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
Power Consumption:
Dimensions:
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 with any
commercially available head eraser once every 50 hours of use.
Refer to the instruction manual of the head eraser for detailed
instructions.
Weight:
Specifications and external appearance are subject to change
without notice because of product improvements.
