Safety "
1. Power Source - The unit should be connected to power supply
only of the type described in the operating instructions or as
marked on the unit.
2. Polarization - If the unit is equipped with a polarized AC power
plug (a plughaving one blade wider than the oe_er),that plugwill
fit into the AC outiet only one way. This is a safety feature, ffyou
are unable to insert the plug fully into the outlet,by reversing the
plug. If the plug should still fail to fit, contact your electricianto
replace your obsoleteoutk_t.Do not defeat the safety purpose of
thepo_zed plug.
3. Power Cord Protection - AC power supply cords should be
routed so that they are not likely to be walked on or pinched by
items placed upon or against tbem. Never take holdof the plug or
cord if your hand is wet, and always grasp the plug body when
connecting or disconnecting it.
4. Nonuse Periods - When the unitisnotused, turnthe poweroff.

Water and Moisture - Do not use this unit near water-for
example, near a bathtub, washbowl, swimming pool, or the like.
Damp basements should also be avoided.
Heat - The unit should be situated away from heat sources
such as radiators and the like. It also should not be placed in
temperatureslessthan5°C (41°1=)or greater than 350C (95°F).
CondensaUon - Moisture mayform on the lens inthe following
conditions..._
• immediately after a heater has been tumed on.

1"ocorrect this problem, turn on the power and wait about one
hour for the moisture to evaporate.
Installation
Environment
1. Outdoor Antenna Grounding - If an outside antenna is con-
nected to the receiver, be sure the antenna system is grounded
so as to provide some protection against voltage surges and
built-up static charges. Section 810 of the National Electrical
Code, ANSI/NFPA No. 70-1990, provides information with re-
spect 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 below.

Listening caution
Selecting fine audio equipment such as the unit you've just pur-
chased is only the start of your musical enjoymant. Now it's tlrneto
consider how you can _ize the fun and excitement your equip-
ment offers. This manufacturer and the Electronic Industries
Association's Consumer Electronics Group went you to get the
most out of your equipment by playing it at a safe level. One that
lets the sound come through loud and clear without annoying blar-
ing or distortion---and, most importantly,without affecting your sen-
sitJvehearing.
We recommend you to avoid prolonged exposure to excessive
noise.
Sound can be deceiving. Over time your heating =comfort level"
adapts to higher volumes of sound. So what sounds "normal" can
actually be loud and harmfqlto your hearing.
Guard against this by setting your equipment at a safe level
BEFORE your hearing adapts.
To establish a safe level:
•Startyour volume controlat a lowsetting.
•Slowly increase the sound until you can hear it comfortably and
dearly, and withoutdistortion.
Once you have established a comfortable sound level:
•Set the dial and leave it there.
Taking a minute to do this now will help to prevent headng damage
or loss in the future. After all, we want you listeningfor a lifetime.

Placement of speaker systems
The illustrationbelow is an example when enjoying Dolby Pro Logic
Surround system and SFC function.
The listeningpositionat which the effect is the greatest is a position
slightly to the rear of a center position of five-speaker systems.
However the position should be adjusted to your personal prefer-
ence, because the effed vades to some degree depending upon
the source.

)
Surround speaker Surround speaker
(Left) (R_t)
Center speaker
The sound reproduced by aspeaker is easily influenced by such
factors as room acoustics and the system's location in the room.
Before finally deciding where the speakers are to be placed, please
readthe following information carefully.
• The bass sound will be increased if the speakers are placed on
the floor or close to a wall due to the reflection of sound.
It istherefore possible to adjust the bass sound to some extent by
adjusting the speaker's distance from the wall and/or floor.
•Undesirable resonance or sound reflection will occur if the speak-
ers face a hard wall or window. Curtains or similar materials can
be used to prevent these reflections.
•To prevent possible acoustic feedback the speaker system should
be kept away from the turntable. Feedback (howling) can result
from vibrationsfrom the speakers.
•Keep the speakers away from sources of heat, high humidity and
direct sunlight.
Note for front/center speakers
These speakers are made so as to be able to he used in close
proximity to the TV, but irregular coloring may result due to how the
system is placed. If such distortionoccurs, turn off the TV for some-
time between 15 and 30 minutes. The demagnetizing function of the
TV will eliminate the distortion. If the irregular coloring isstill visible,
then move the speakers further away from the TV.
Please note that if there isa magnetic object near the I"V, irregular
_olodng may result due to the interaction between the TV and the
speaker.
