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 plug having one blade wider than the other), that plug will
fit into the AC 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.

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 them. Never take hold of 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 unit is not used, turn the power off.
When left unused for a long period of time, the unit should be
unplugged from the household AC outlet.

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,
ANSl/NFPA No, 70-1990, provides information with respect to
proper grounding of the mast and supporting structure, ground
ing of the lead-in wire to an antenna discharge unit, size of
grounding conductors, location of antenna-discharge unit, con
nection to grounding electrodes, and requirements for the

grounding electrode. See figure below.

3. Heat—The unit should be situated away from heat sources such
as radiators and the like.
It also should not be placed in temperatures less than 5“C (41°F) or
greater than 35“C (95“F).

4. Condensation—Moisture may form on the lens in the following
conditions...

•immediately after a heater has been turned on.

•in a steamy or very humid room.

•when the unit is suddenly moved from a cold environment to a

warm one.

If moisture forms inside this unit, it may not operate properly. To

correct this problem, turn on the power and wait about one hour
for the moisture to evaporate.

Placement

1.

Ventilation—The unit should be situated so that its location or
position does not interfere with its proper ventilation. Allow

10 cm (4") clearance from the rear of the unit.

2.

Foreign Material—Care should be taken so that objects do not fall
into and liquids are not spilled into the unit. Do not subject this
unit to excessive smoke, dust, mechanical vibration, or shock.
Magnetism—The unit should be situated away from equipment
or devices that generate strong magnetic fields.
Stacking—Do not place heavy objects, other than system compo
nents, on top of the unit.
Surface—Place the unit on a flat, level surface.
Carts and Stands—The unit should be used only with a cart or
stand that is recommended by the manufacturer.

Concerning the remote control

Listening caution

Selecting fine audio equipment such as the unit you've just pur
chased is only the start of your musical enjoyment. No%v it's time to
consider how you can maximize the fun and excitement your equip
ment offers. This manufacturer and the Electronic Industries
Association's Consumer Electronics Group want 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 blaring or
distortion—and, most importantly, without affecting your sensitive
hearing.

We recommend you to avoid prolonged exposure to excessive noise.

Sound can be deceiving. Over time your hearing "comfort level"
adapts to higher volumes of sound. So what sounds "normal" can
actually be loud and harmful to your hearing.
Guard against this by setting your equipment at a safe level BEFORE
your hearing adapts.
To establish a safe level:

•Start your volume control at a low setting.

•Slowly increase the sound until you can hear it comfortably and
clearly, and without distortion.

Once you have established a comfortable sound level:

•Set the dial and leave it there.

Battery installation

• Do not mix old and new batteries, or batteries of different types
(manganese and alkaline, etc.).

• Never subject batteries to excessive heat or flame; do not attempt to
disassemble them; and be sure they are not short-circuited,

• If the remote control is not to be used for a long period of time,
remove the batteries and store them in a cool, dark place.

• Do not attempt to recharge alkaline or manganese batteries.

• Do not use rechargeable type batteries.

Battery life

The battery life is about one year.

The batteries should be replaced if commands from the remote con
trol transmitter do not operate the unit even when the transmitter is
held close to the front panel.

o

Taking a minute to do this now will help to prevent hearing damage
or loss in the future. After all, we want you listening for a lifetime.

Correct method of use

• Do not place obstacles between the remote control signal sensor and
remote control unit,

• Do not expose the remote control signal sensor to direct simlight or
to the bright light of an invertor fluorescent light.

•Take care to keep the remote control signal sensor and end of the
remote control unit free from dust.

• If this system is installed in a rack with glass doors, the glass doors'
thickness or color might make it necessary to use the remote control

a shorter distance from the system.

To prevent damage

• Do not place heavy items.

• Do not disassemble or reconstruct.

• Do not spill water or other liquids.

Connecffons

Basic connections (for supplied accessories)

Before making connections:

•Make sure you correctly identify the left/right sides before placing the speakers, (see page 7.)

Ql

For your reference

•You can take the front net off speakers,

• For your listening pleasure, keep your speakers from touching the
system.

Caution
Use the speakers only with the recommended
system. Failure to do so may lead to damage to
the amplifier and/or the speakers, and may
result in the risk of fire. Consult a qualified
service person if damage has occurred or if you

experience a sudden change in performance.

Placement of surround speakers

We recommend that surround speakers be placed on the side of or
slightly behind the listener at ear level.
However the position should be adjusted to your personal prefe
rence, because the effect varies to some degree depending upon the
type of music and the music source.

Optional surround speaker
connections

Connecting the surround speakers produces a feeling of depth and
movement of sound, and provides the listener with a feeling of
presence like that of a movie theater.
