Precautions
1. Recording Copyright—Unless it’s for personal use only,
recording copyrighted material is illegal without the permis-
sion of the copyright holder.
• Low cost cassettes with no guide roller or pressure pad
spring should never be used for stereo.
• C-100–120 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 over-
heat.
2. AC Fuse—The AC fuse inside the unit is not user-serviceable.
If you cannot turn on the unit, contact your Onkyo dealer.
3. Care—Occasionally you should dust the unit all over with a
soft cloth. For stubborn stains, use a soft cloth dampened with
a weak solution of mild detergent and water. Dry the unit
immediately afterwards with a clean cloth. Don’t use abrasive
cloths, thinners, alcohol, or other chemical solvents, because
they may damage the finish or remove the panel lettering.
9. Moisture Condensation
Moisture condensation may damage this unit.
Read the following carefully:
• Moisture condensation can occur in the following situa-
tions:
– The unit is moved from a cold place to a warm place.
– A heater is turned on, or cold air from an air conditioner
is hitting the unit.
– In the summer, when this unit is moved from an air con-
ditioned room to a hot and humid place.
– The unit is used in a humid place.
4. Power
WARNING
BEFORE PLUGGING IN THE UNIT FOR THE FIRST
TIME, READ THE FOLLOWING SECTION CAREFULLY.
AC outlet voltages vary from country to country. Make sure
that the voltage in your area meets the voltage requirements
printed on the unit’s rear panel (e.g., AC 230 V, 50 Hz or AC
120 V, 60 Hz).
• Do not use this unit when there’s the possibility of mois-
ture condensation occurring. Doing so may damage your
cassettes and certain parts inside this unit.
If condensation does occur, remove all cassettes and leave this
unit turned on for two to three hours. By this time, the unit will
have warmed up and any condensation will have evaporated.
Setting the [STANDBY/ON] switch to STANDBY does not
fully shutdown the unit. If you do not intend to use the unit for
an extended period, remove the power cord from the AC outlet.
5. Never Touch this Unit with Wet Hands—Never handle this
unit or its power cord while your hands are wet or damp. If
water or any other liquid gets inside this unit, have it checked
by your Onkyo dealer.
For British models
6. Handling Notes
• If you need to transport this unit, use the original packag-
ing to pack it how it was when you originally bought it.
• Do not leave rubber or plastic items on this unit for a long
time, because they may leave marks on the case.
• This unit’s top and rear panels may get warm after pro-
longed use. This is normal.
• If you do not use this unit for a long time, it may not work
properly the next time you turn it on, so be sure to use it
occasionally.
Replacement and mounting of an AC plug on the power supply
cord of this unit should be performed only by qualified service
personnel.
IMPORTANT
The wires in the 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 termi-
nal which is marked with the letter N or coloured black.
The wire which is coloured brown must be connected to the ter-
minal which is marked with the letter L or coloured red.
• When you’ve finished using this unit, remove cassettes and
turn off the power.
7. 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 heat-
ing 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.
• Be extremely careful with the recording/playback heads.
Clean and demagnetize them regularly, but under no cir-
cumstances should magnets or other metals be used any-
where near the heads.
IMPORTANT
The plug is fitted with an appropriate fuse. If the fuse needs to be
replaced, the replacement fuse must approved by ASTA or BSI to
BS1362 and have the same ampere rating as that indicated on the
plug. Check for the ASTA mark or the BSI mark on the body of
the fuse.
If the power cord’s plug is not suitable for your socket outlets, cut
it off and fit a suitable plug. Fit a suitable fuse in the plug.
• 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.
For Canadian Models
For models having a power cord with a polarized plug:
CAUTION: TO PREVENT ELECTRIC SHOCK, MATCH
WIDE BLADE OF PLUG TO WIDE SLOT, FULLY INSERT.
8. Cassettes to Avoid:
• Cassettes with poorly formed cases that rattle during
rewind and fast forward.

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.
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 mag-
netic coating than open reel tapes. The thin coating gives the tape
a comparatively low saturation level which can easily be sur-
passed if the recording level is set too high.
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 max-
imum output level of cassette tapes by more than 4 dB at 10 kHz.
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-RW255 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-RW255.
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 simulta-
neously.
Notes:
1. Even if the CD player is stopped during recording, the cas-
sette 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.

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:
• 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
Residual magnetism builds up in the heads after the cassette deck
has been used for an extended period of time. This buildup intro-
duces noise and static into tapes and impairs high frequency
response. To prevent this, demagnetize the heads with any com-
mercially available head eraser once every 50 hours of use.
Refer to the instruction manual of the head eraser for detailed
instructions.
