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.

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.)
• Plug the AC power supply cord into a household AC outlet only after all other connections have been made.

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
