Read Instructions — Ali the safety and operating instructions
should be read before the unit is operated.
Retain Instructions — The safety and operating instructions
should be retained for future reference.
Head Warnings — All warnings on the unit and in the
operating instructions should be adhered to.
Follow Instructions — Ail operating and use instructions
should be followed.
Water and Moisture — The unit should not be used near
water — for example, near a bathtub, washbowl, kitchen
sink, in a wet basement, or near a swimming pool.
Carts and Stands — The unit should be used only with a
cart or stand that is recommended by the manufacturer.
Wall or Ceiling Mounting — The unit should be mounted
to a wall or ceiling only as recommended by the
manufacturer.
Ventilation — The unit should be situated so that its
location or position does not interfere with its proper
ventilation. For example, the unit should not be situated on
a bed, sofa, rug, or similar surface that may biock the
ventilation apenings Or placed in a built-in installation, such
as a bookcase or cabinet, that may impede the flow of air
through the ventilation openings.
Heat — The unit should be situated away from heat sources
such as radiators, heat registers, or other appliances (includ-
ing amplifiers) that produce heat.
Power Sources — The unit should be connected to a power
supply only of the type described in the operating
instructions or as marked on the unit.
Grounding or Polarization — The unit should be property
grounded and correct polarization observed.
Power-Cord Protection — Power-supply cords should be
routed so that they are not likely to be waiked on or
pinched by items placed upon or against them, paying
particular attention to cords at plugs, convenience
receptacies, and the point where they exit from the unit.
Cleaning — The unit should be cleaned only as recommended
by the manufacturer. Cleaning of internal parts must be
performed only by qualified service personnel. Removing
the cabinet exposes you to the danger of receiving an electric
shock and can even cause the unit to malfunction. From
time to time you should wipe off the front and rear panels
and the cabinet with a silicon or other soft cloth.
For heavier dirt, dampen a soft cloth in a weak solution of
mild detergent and water, wring it out dry, and wipe away
the dirt. Following this, dry immediately with a clean cloth.
Do not use rough material, thinner, alcohol, or other
chemical solvents or cloths, since these may damage the
finish or remove the panei lettering.
Power Lines — An outdoor antenna should be located away
from power lines.
Outdoor Antenna Grounding — if an outdoor antenna is
connected to the receiver, be sure the antenna system is
grounded so as to provide some protection against vol tage
surges and built up static charges.

provides
information
with
respect
to
proper grounding of the mast and supporting structure,
grounding of the lead-in wire to an antenna discharge unit,
size of grounding conductors, location of antenna-discharge
unit,
connection
to
grounding
electrodes,
and
requirements
for the grounding electrode. See Figure 1.
Periods of Nonuse — The power cord of the unit should be
unplugged from the outlet when left unused for a long
period of time.

Use no. 10 AWG copper or No. 8 AWG aluminum or
No. 17 AWG copper-clad steel or bronze wire, or larger
as ground wires for both mast and lead-in.
Secure lead-in wire from antenna to antenna discharge unit
and mast ground wire to house with stand-off insulators,
spaced from 4 feet (1.22 meters) to 6 feet (1.83 meters)
apart.
Mount antenna discharge unit as closely as possible to
where lead-in enters house.
18. Servicing — The user should not attempt to service this unit
beyond that described in the operating instructions. All
other servicing should be referred to qualified service
personne!.
AC Fuse and Speaker Protection Fuse
The fuses are located inside the chassis and are not user
serviceable. |f power does not come on, contact your
Onkyo dealer.
Memory Preservation
This unit does not require memory preservation batteries. A built-
in memory power back-up system preserves the contents of the
memory during power failures and even when the unit is unplugged.
The unit must be plugged in and the power switch turned on and
off once in order to charge the back-up system. Note that since this
is NOt a permanent memory, the power switch must be turned on
and off a few times each month to keep the back-up system operable.
The period of time during which memory contents are preserved
after power has last been turned off varies depending on climate
and the location and placement of the unit. On the average,
memory contents are protected over a period of 3 to 4 weeks {a
minimum of 2 weeks) after the last time power has been turned
off. This period is shorter when the unit is exposed to very high
humidity or used in an area with an extremely humid climate.
