We Want You Listening for a Lifetime

Yamaha and the Electronic Industries Association’s Consumer Electronics Group want you to get the most enjoyment out of your equipment by playing it at a safe level

— a level that lets the sound come through loud and clear without annoying blaring or distortion — and, most importantly, without damaging your sensitive hearing.

Since hearing damage from loud sounds is often undetectable until it is too late, Yamaha and the Electronic Industries Association’s Consumer Electronics Group recommend that you avoid prolonged exposure to excessive volume levels.

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 excessive 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 discolor 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 speakers.

•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 responsibility. 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’ maximum 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 circumstances.

•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 overheat, possibly causing damage.

•Do not use excessive force on switches, controls or connection wires. When moving this unit, ﬁrst disconnect 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 condensation inside this unit by allowing enough space around the unit and avoiding excess humidiﬁcation. Condensation might cause ﬁre, damage to the unit, or electric shock.

•Do not cover the rear panel of this unit with a newspaper, 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 connections 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, damage 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 continuously 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 continuously output, or if a turntable stylus touches the surface of a disc, reduce the volume level to prevent the unit from being damaged.

•If you hear distorted noise (i.e., unnatural, intermittent “rapping” or “hammering” sounds) from this unit, reduce the volume level. Extremely loud movie soundtrack low frequency, bass-heavy sounds, or similarly 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.
