Precautions
•
To assure the finest performance, please read this
manual carefully. Keep it in a safe place for future
reference.
•
Install the speakers in a cool, dry, clean place – away
from windows, sources of heat, sources of excessive
vibration, dust, moisture or cold. Avoid sources of
electrical humming (e.g., transformers and motors).
To prevent fire or electric shock, do not expose the
speakers to rain or water.
•
To prevent the enclosure from warping or discoloring,
do not expose the speakers to direct sunlight or exces-
sive humidity.
•
Avoid installing the speakers where foreign objects
may fall onto them and/or where they may be
exposed to liquid dripping or splashing.
•
Do not place the following objects on top of the
speakers:
• Other components, as they might damage or dis-
color the surface of the speakers;
• Burning objects (e.g., candles), as they might cause
fire, damage to the speakers or personal injury;
• Containers of liquid, as they might spill and cause
electric shock to the user or damage to the speak-
ers.
•
Do not place the speakers where they are liable to be
knocked over or struck by falling objects. Stable
placement will also ensure better sound.
•
Placing the speakers on the same shelf or rack as the
turntable can result in feedback.
•
Secure placement or installation is the owner’s respon-
sibility. Yamaha is not liable for accidents caused by
improper placement or installation of speakers.
•
If you note distortion, reduce the volume control on
your amplifier. Do not drive your amplifier to the
point of “clipping.” Otherwise, the speakers may be
damaged.
•
When using an amplifier with a rated output power
higher than the nominal input power of the speakers,
care should be taken not to exceed the speakers’ max-
imum input.
•
Do not clean the speakers with chemical solvents as
this might damage the finish. Use a clean, dry cloth.
•
Do not attempt to modify or fix the speakers. Contact
qualified Yamaha service personnel when service is
needed. Do not open the cabinet under any circum-
stances.
•
Please read the “Troubleshooting” section regarding
common operating errors before concluding that the
speakers are faulty.
For the SW-P240
•
Do not operate this unit upside down. It may over-
heat, possibly causing damage.
•
Do not use excessive force on switches, controls or
connection wires. When moving this unit, first dis-
connect the power plug and the wires connected to
other equipment. Never pull the wires themselves.
•
Since this unit has a built-in power amplifier, heat
radiates from the rear panel. Place the unit away from
walls, allowing at least 20 cm of space above, behind
and on both sides of the unit to prevent fire or dam-
age. Furthermore, do not position the unit with the
rear panel facing down on the floor or other surfaces.
•
When using a humidifier, be sure to avoid condensa-
tion inside this unit by allowing enough space around
the unit and avoiding excess humidification. Conden-
sation might cause fire, damage to the unit, or electric
shock.
•
Do not cover the rear panel of this unit with a news-
paper, tablecloth, curtain, etc. to avoid obstructing
heat radiation. If the temperature inside the unit rises,
it may cause fire, damage to the unit, or personal
injury.
•
Do not plug this unit into a wall outlet until all con-
nections are complete.
•
The voltage to be used must match that specified on
the rear panel. Using this unit with a voltage higher
than specified is dangerous and may cause fire, dam-
age to the unit, or personal injury. Yamaha is not
responsible for damage resulting from use of this unit
with a voltage other than specified.
•
To prevent damage from lightning, disconnect the AC
power plug during electric storms.
•
Super-bass frequencies reproduced by this unit may
cause a turntable to generate audio feedback. In this
case, move the unit away from the turntable.
•
This unit may be damaged if certain sounds are con-
tinuously output at high volume level. For example, if
20Hz–50Hz sine waves from a test disc or bass
sounds from an electronic instrument, etc. are contin-
uously output, or if a turntable stylus touches the sur-
face of a disc, reduce the volume level to prevent the
unit from being damaged.
•
If you hear distorted noise (i.e., unnatural, intermit-
tent “rapping” or “hammering” sounds) from this
unit, reduce the volume level. Extremely loud movie
soundtrack low frequency, bass-heavy sounds, or sim-
ilarly loud popular music passages can damage the
speaker system.
•
Vibration generated by super-bass frequencies may
distort images on a TV. In this case, move the unit
away from the TV set.
•
When disconnecting the power cord from the wall
outlet, grasp the plug; do not pull the cord.
•
When you plan not to use this unit for a long period
of time (i.e., vacation, etc.) disconnect the AC power
plug from the wall outlet.
•
Do not place much pressure against the subwoofer
net. It may break the net or the unit may fall, resulting
in injury.
•
Do not place anything fragile beside the subwoofer.
The air pressure produced by the subwoofer may
break the objects and cause malfunction or injury.
WARNING
TO REDUCE THE RISK OF FIRE OR ELECTRIC
SHOCK, DO NOT EXPOSE THIS UNIT TO RAIN
OR MOISTURE.
