Yamaha will not be held responsible for any damage and/
or injury caused by not
following the cautions below.
• To assure the finest performance, please read this
manual carefully. Keep it in a safe place for future
reference.
• Install this unit in a cool, dry, clean place - away from
windows, heat sources, sources of excessive vibration,
dust, moisture and cold. Avoid sources of humming
(transformers, motors). To prevent fire or electrical
shock, do not expose this unit to rain or water.
• The voltage to be used must be the same as that specified
on the rear panel. Using this unit with a higher voltage
than specified is dangerous and may cause a fire and/or
electric shock.
• Do not use force on switches, controls or connection
wires. When moving the unit, first disconnect the power
plug and the wires connected to other equipment. Never
pull the wires themselves.
• When not planning to use this unit for a long period (ie.,
vacation, etc.), disconnect the AC power plug from the
wall outlet.
• To prevent lightning damage, disconnect the AC power
plug when there is an electric storm.
• Since this unit has a built-in power amplifier, heat will
radiate from the rear panel. Place the unit apart from the
walls, allowing at least 20 cm of space above, behind and
on both sides of the unit to prevent fire or damage.
Furthermore, do not position with the rear panel facing
down on the floor or other surfaces.
• Do not cover the rear panel of this unit with a newspaper,
a tablecloth, a curtain, etc., in order not to obstruct heat
radiation. If the temperature inside the unit rises, it may
cause fire, damage to the unit and/or personal injury.
• Do not place the following objects on this unit:
- Glass, china, small metallic, etc.
If glass, etc., falls as a result of vibrations and breaks,
it may cause bodily injury.
- A burning candle etc.
If the candle falls as a result of vibration, it may cause
fire and bodily injury.
- A vessel containing water
If the vessel falls as a result of vibration and water
spills, it may cause damage to the speaker, and/or you
may get an electric shock.
• Do not place this unit where foreign material, such as
dripping water. It might cause fire, damage to this unit,
and/or personal injury.
• Never put a hand or a foreign object into the YST port
located on the right side of this unit. When moving this
unit, do not hold the port, as it might cause personal
injury and/or damage to this unit.
• Never place a fragile object near the YST port of this
unit. If the object falls or drops as a result of the air
pressure, it may cause damage to the unit and/or personal
injury.
• Never open the cabinet. It might cause an electric shock,
since this unit uses a high voltage. It might also cause
personal injury and/or damage to this unit. If something
drops into the set, contact your dealer.
• When using a humidifier, be sure to avoid condensation
inside this unit by allowing enough space around this
unit or avoiding excess humidification. Condensation
might cause fire, damage to this unit, and/or electric
shock.
• Super-bass frequencies reproduced by this unit may
cause a turntable to generate a howling sound. In such a
case, move this unit away from the turntable.
• This unit may be damaged if certain sounds are
continuously output at high volume level. For example,
if 20 Hz - 50 Hz sine waves from a test disc, bass sounds
from electronic instruments, etc., are continuously
output, or when the stylus of a turntable touches the
surface of a disc, reduce the volume level to prevent this
unit from being damaged.
• If you hear distortion (i.e., unnatural, intermittent
“rapping” or “hammering” sounds) coming from this
unit, reduce the volume level. Extremely loud playing of
a movie soundtrack’s low frequency, bass-heavy sounds
or similarly loud popular music passages can damage
this speaker system.
• Vibration generated by super-bass frequencies may
distort images on a TV. In such a case, move this unit
away from the TV set.
• Do not attempt to clean this unit with chemical solvents
as this might damage the finish. Use a clean, dry cloth.
• Be sure to read the “TROUBLESHOOTING” section
regarding common operating errors before concluding
that the unit is faulty.
• Install this unit near the wall outlet and where the AC
power plug can be reached easily.
• Secure placement or installation is the owner’s
responsibility. Yamaha shall not be liable for any
accident caused by improper placement or
installation of speakers.
CAUTION: Read this before operating your unit
