1. Read these instructions.

2. Keep these instructions.

3. Heed all warnings.

4. Follow all instructions.

5. Do not use this apparatus near water.

6. Clean only with dry cloth.

7. Do not block any ventilation openings. Install in

accordance with the manufacturer's instructions.

8. Do not install near any heat sources such as radia-

tors, heat registers, stoves, or other apparatus

(including amplifiers) that produce heat.

9. Do not defeat the safety purpose of the polarized or

grounding-type plug. A polarized plug has two

blades with one wider than the other. A grounding

type plug has two blades and a third grounding

prong. The wide blade or the third prong are pro-

vided for your safety. If the provided plug does not

fit into your outlet, consult an electrician for

replacement of the obsolete outlet.

10. Protect the power cord from being walked on or

pinched particularly at plugs, convenience recepta-

cles, and the point where they exit from the appara-

tus.

11. Only use attachments/accessories specified by the

manufacturer.

12. Use only with the cart, stand,

tripod, bracket, or table spec-

ified by the manufacturer, or

sold

with

the

apparatus.

When a cart is used, use cau-

tion

when

moving

the

cart/apparatus

combination

to avoid injury from tip-over.

13. Unplug this apparatus during lightning storms or

when unused for long periods of time.

14. Refer all servicing to qualified service personnel.

Servicing is required when the apparatus has been

damaged in any way, such as power-supply cord or

plug is damaged, liquid has been spilled or objects

have fallen into the apparatus, the apparatus has

been exposed to rain or moisture, does not operate

normally, or has been dropped.

15. Damage Requiring Service

Unplug the apparatus from the wall outlet and refer

servicing to qualified service personnel under the

following conditions:

A. When the power-supply cord or plug is dam-

aged,

B. If liquid has been spilled, or objects have fallen

into the apparatus,

C. If the apparatus has been exposed to rain or

water,

D. If the apparatus does not operate normally by

following the operating instructions. Adjust only

those controls that are covered by the operating

instructions as an improper adjustment of other

controls may result in damage and will often

require extensive work by a qualified technician

to restore the apparatus to its normal operation,

E. If the apparatus has been dropped or damaged in

any way, and

F. When the apparatus exhibits a distinct change in

performance this indicates a need for service.

16. Object and Liquid Entry

Never push objects of any kind into the apparatus

through openings as they may touch dangerous volt-

age points or short-out parts that could result in a

fire or electric shock.

The apparatus shall not be exposed to dripping or

splashing and no objects filled with liquids, such as

vases shall be placed on the apparatus.

Don't put candles or other burning objects on top of

this unit.

17. Batteries

Always consider the environmental issues and fol-

low local regulations when disposing of batteries.

18. If you install the apparatus in a built-in installation,

such as a bookcase or rack, ensure that there is ade-

quate ventilation.

Leave 20 cm (8") of free space at the top and sides

and 10 cm (4") at the rear. The rear edge of the shelf

or board above the apparatus shall be set 10 cm (4")

away from the rear panel or wall, creating a flue-like

gap for warm air to escape.

WARNING:

TO REDUCE THE RISK OF FIRE OR ELECTRIC

SHOCK, DO NOT EXPOSE THIS APPARATUS

TO RAIN OR MOISTURE.

1. Recording Copyright--Unless it's for personal use

only, recording copyrighted material is illegal with-

out the permission of the copyright holder.

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 deter-

gent and water. Dry the unit immediately afterwards

with a clean cloth. Don't use abrasive cloths, thin-

ners, alcohol, or other chemical solvents, because

they may damage the finish or remove the panel let-

tering.

4. Power

WARNING

BEFORE PLUGGING IN THE UNIT FOR THE

FIRST TIME, READ THE FOLLOWING SEC-

TION 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).

Some models have a voltage selector switch for

compatibility with power systems around the world.

Before you plug in such a model, make sure that the

voltage selector is set to the correct voltage for your

area.

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.

6. Handling Notes

· If you need to transport this unit, use the original

packaging to pack it how it was when you origi-

nally 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 prolonged 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.

For British models

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 mark-

ings 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.

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.
