Instruction Manual
Operations

1. Read Instructions All the safety and operating instructions
should be read before the appliance is operated.
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.
4. Follow Instructions All operating and use instructions
should be followed.
5. Cleaning Unplug the appliance from the wall outlet before
cleaning. The appliance should be cleaned only as recom-
mended by the manufacturer.
6. Attachments Do not use attachments not recommended by
the appliance manufacturer as they may cause hazards.
7. Water and Moisture Do not use the appliance near water for
example, near a bath tub, wash bowl, kitchen sink, or laundry
tub; in a wet basement; or near a swimming pool; and the like.
8. Accessories Do not place the appliance on an unstable cart,
stand, tripod, bracket, or table. The appliance may fall, causing
serious injury to a child or adult, and serious damage to the
appliance. Use only with a cart, stand, tripod, bracket, or table
recommended by the manufacturer, or sold with the appliance.
Any mounting of the appliance should follow the
manufacturer's instructions, and
should use a mounting accessory
recommended by the manufac-
turer.
9. An appliance and cart combina-
tion should be moved with care.
Quick stops, excessive force, and
uneven surfaces may cause the
appliance and cart combination to
overturn.
10. Ventilation Slots and openings in the cabinet are provided
for ventilation and to ensure reliable operation of the appliance
and to protect it from overheating, and these openings must not
be blocked or covered. The openings should never be blocked
by placing the appliance on a bed, sofa, rug, or other similar
surface. The appliance should not be placed in a built-in instal-
lation such as a bookcase or rack unless proper ventilation is
provided. There should be free space of at least 20 cm (8 in.)
and an opening behind the appliance.
11. Power Sources The appliance should be operated only from
the type of power source indicated on the marking label. If you
are not sure of the type of power supply to your home, consult
your appliance dealer or local power company.
12. Grounding or Polarization The appliance may be equipped
with a polarized alternating current line plug (a plug having one
blade wider than the other). This plug will fit into the power
outlet only one way. This is a safety feature. If you are unable to
insert the plug fully into the outlet, try reversing the plug. If the
plug should still fail to fit, contact your electrician to replace
your obsolete outlet. Do not defeat the safety purpose of the
polarized plug.
13. 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 cords at plugs, convenience receptacles, and the point where
they exit from the appliance.
14. Lightning For added protection for the appliance during a
lightning storm, or when it is left unattended and unused for
long periods of time, unplug it from the wall outlet and discon-
nect the antenna or cable system. This will prevent damage to
the appliance due to lightning and power-line surges.
15. Overloading Do not overload wall outlets, extension cords,
or integral convenience receptacles as this can result in a risk
of fire or electric shock.
16. Object and Liquid Entry Never push objects of any kind
into the appliance through openings as they may touch danger-
ous voltage points or short-out parts that could result in a fire or
electric shock. Never spill liquid of any kind on the appliance.
17. Servicing Do not attempt to service the appliance yourself as
opening or removing covers may expose you to dangerous volt-
age or other hazards. Refer all servicing to qualified service
personnel.
18. Damage Requiring Service Unplug the appliance form the
wall outlet and refer servicing to qualified service personnel
under the following conditions:
A. When the power-supply cord or plug is damaged,
B. If liquid has been spilled, or objects have fallen into the
appliance,
C. If the appliance has been exposed to rain or water,
D. If the appliance does not operate normally by following the
operating instructions. Adjust only those controls that are
covered by the operating instructions as an improper ad-
justment of other controls may result in damage and will
often require extensive work by a qualified technician to
restore the appliance to its normal operation,
E. If the appliance has been dropped or damaged in any way,
and
F. When the appliance exhibits a distinct change in perfor-
mance this indicates a need for service.
19. Replacement Parts When replacement parts are required, be
sure the service technician has used replacement parts specified
by the manufacturer or have the same characteristics as the
original part. Unauthorized substitutions may result in fire,
electric shock, or other hazards.
20. Safety Check Upon completion of any service or repairs to the
appliance, ask the service technician to perform safety checks to
determine that the appliance is in proper operation condition.
21. Wall or Ceiling Mounting The appliance should be mounted
to a wall or ceiling only as recommended by the manufacturer.
22. Heat The appliance should be situated away from heat
sources such as radiators, heat registers, stoves, or other appli-
ances (including amplifiers) that produce heat.
23. Liquid Hazards The appliance shall not be exposed to drip-
ping or splashing and no objects filled with liquids, such as
vases shall be placed on the appliance.
Important Safeguards

2. AC Fuse
The fuse is located inside the chassis and is not user-serviceable. If
power does not come on, contact your Integra/Onkyo authorized

3. Care
From time to time you should wipe the front and rear panels and the
cabinet with a soft cloth. For heavier dirt, dampen a soft cloth in a
weak solution of mild detergent and water, wring it out dry, and
wipe off the dirt. Following this, dry immediately with a clean
cloth. Do not use rough material, thinners, alcohol or other chemi-
cal solvents or cloths since these could damage the finish or remove
the panel lettering.
