2、erformance,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
3、,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
4、 unit,first disconnect the power plug and the wires connected to other equipments.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.Since this unit has a built-in power amplifier,heat will radiate
5、 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 ne
6、wspaper,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 by vibrations and breaks,
7、it may cause bodily injury.-A burning candle etc.If the candle falls by vibrations,it may cause fire and bodily injury.-A vessel with water in it If the vessel falls by vibrations and water spills,it may cause damage to the speaker,and/or you may get an electric shock.Do not place this unit where fo
8、reign objects such as water drips might fall.It might cause a fire,damage to this unit,and/or personal injury.Never put a hand or a foreign object into the YST port located on the front side of this unit.When moving this unit,do not hold the port as it might cause personal injury and/or damage to th
9、is unit.Never place a fragile object near the YST port of this unit.If the object falls or drops by 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
10、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 spaces around this unit or avoiding excess humidification.Condensation might cause a fire,damage to this unit,and/or electric shock
11、.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
12、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 distorted noise(i.e.,unnatural,intermittent“rapping”or“hammering”sounds)coming from this unit,red
13、uce the volume level.Extremely loud playing of a movie soundtracks 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 no
14、t 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
15、reached easily.The batteries shall not be exposed to excessive heat such as sunshine,fire or the like.-Keep the batteries in a location out of reach of children.Batteries can be dangerous if a child were to put in his or her mouth.-If the batteries grow old,the effective operation range of the remot
16、e control decreases considerably.If this happens,replace the batteries with new one as soon as possible.-Do not use old batteries together with new ones.-Do not use different types of batteries(such as alkalineand manganese batteries)together.Read the packaging carefully as these different types of
17、batteries may have the same shape and color.-Exhausted batteries may leak.If the batteries have leaked,dispose of them immediately.Avoid touching the leaked material or letting it come into contact with clothing,etc.Clean the battery compartment thoroughly before installing new batteries.-If you pla
18、n not to use the unit for a long period of time,remove the batteries from the unit.Otherwise,the batteries will wear out,possibly resulting in a leakage of battery liquid that may damage the unit.-Do not throw away batteries with general house waste.Dispose of them correctly in accordance with your
19、local regulations.Secure placement or installation is the owners responsibility.Yamaha shall not be liable for any accident caused by improper placement or installation of speakers.CAUTION:Read this before operating your unit.CAUTIONDanger of explosion if battery is incorrectly replaced.Replace only
20、 with the same or equivalent type.WARNINGTO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK,DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.ii EnEnglishVOLTAGE SELECTOR(Asia and General models only)The voltage selector switch on the rear panel of this unit must be set for your local main voltage BEFORE p

48、uld this happen,move this unit away from the TV set.If the speaker volume is very loud,furniture or window glass may resonate and the subwoofer itself may vibrate.In this case,lower the volume level.To limit resonance,use a thick curtain or similar cloth that tends to absorb sound vibrations effecti
