CAUTION: READ THIS BEFORE OPERATING YOUR UNIT.

iii

1 To assure the finest performance, please read this manual

carefully. Keep it in a safe place for future reference.

2 Install the speakers 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 electric shock, do not expose the

speakers to rain or water.

3 To prevent the enclosure from warping or discoloring, do not

place the speakers where they will be exposed to direct

sunlight or excessive humidity.

4 Avoid installing the speakers where foreign objects may fall

onto them and/or where they may be exposed to liquid

dripping or splashing.

5 Do not place the following objects on top of the speakers:

– Other components, as they might cause damage and/or

discoloration on the surface of the speakers.

– Burning objects (i.e. candles), as they might cause fire,

damage to the speakers and/or personal injury.

– Containers with liquid in them, as they might cause

electric shock to the user and/or damage to the speakers.

6 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 performance.

7 Placing the speakers on the same shelf or rack as the

turntable can result in feedback.

8 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.

9 Any time you note distortion, reduce the volume control on

your amplifier to a lower setting. Never allow your amplifier

to be driven into “clipping”. Otherwise the speakers may be

damaged.

10 When using an amplifier with a rated output power higher

than the nominal input power of the speakers, care should be

taken never to exceed the maximum input of the speakers.

11 Do not attempt to clean the speakers with chemical solvents

as this might damage the finish. Use a clean, dry cloth.

12 Do not attempt to modify or fix the speakers. Contact

qualified YAMAHA service personnel when any service is

needed. The cabinet should never be opened for any reason.

13 Be sure to read the “TROUBLESHOOTING” section

regarding common operating errors before concluding that

the speakers are faulty.

For SW-P440

1 Do not operate this unit upside down. It may overheat,

possibly causing damage.

2 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.

3 Since this unit has a built-in power amplifier, heat will radiate

from the rear panel. Place the unit apart from the walls,

allowing spaces of at least 20 cm 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.

4 When using a humidifier, be sure to avoid condensation

inside this unit by allowing enough spaces around this unit or

avoiding excess humidification. Condensation might cause a

fire, damage to this unit, and/or electric shock.

5 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 this unit rises, it may

cause fire, damage to this unit, and/or personal injury.

6 Do not plug in this unit to a wall outlet until all connections

are completed.

7 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 fire, damage to this

unit, and/or personal injury. YAMAHA will not be held

responsible for any damage resulting from use of this unit

with a voltage other than specified.

8 Super-bass sound reproduced by this unit may cause a

turntable to generate a howling sound. In such a case, move

this unit away from the turntable.

9 This unit may be damaged if certain sounds are continuously

outputted 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 outputted, or when the

stylus of a turntable touches the surface of a disc, reduce the

volume level to prevent this unit from being damaged.

10 If you hear distorted noise (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 unit.

11 Vibration generated by super-bass sound may distort images

on a TV. In such a case, move this unit away from the TV set.

12 When disconnecting the power cord from the wall outlet,

grasp the plug; do not pull the cord.

13 When not planning to use this unit for a long period (i.e.

vacation, etc.), disconnect the AC power plug from the wall

outlet.

14 Install this unit near the wall outlet and where the AC power

plug can be reached easily.

CAUTION: READ THIS BEFORE OPERATING YOUR UNIT.

This unit features a magnetically shielded design, but there is

still a chance that placing it too close to a TV set might impair

picture color. Should this happen, move this unit away from

the TV set.

As long as this unit is connected to the AC wall outlet,

it is not disconnected from the AC power source even

if you turn off this unit by POWER.
