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.

Handling cassette tapes  
Examine cassette tapes carefully before using them with the casette tape deck.  
Erasure prevention  
A
B
Cassette tapes are constructed with erasure  
prevention tabs to prevent accidental era-  
sure of the tape.  
1
If you wish to protect a recording from  
accidental erasure, break off the tab(s)  
on the appropriate side(s). It will no  
longer be possible to use the recording  
button with such a cassette.  
A
1.  
2.  
2
If at some later date you wish to record  
the cassette, simply cover the hole(s)  
with small pieces of cellophane tape.  
• Take care not to cover the tape type ID  
holes.  
High position  
detection hole  
Loose tape  
Loose tape can cause tangling around the  
pinch roller and capstan and jam the mech-  
anism. Remove any tape slack with a pen-  
cil or similar device as shown in the  
diagram.  
A
Tapes not recommended  
1. C-100–120 tapes  
C-100–120 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:  
• 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.
