    On safety Completely disconnect the powercord (mains lead) from the wall socket

    (mains) if it is not going to be usedfor an extended period of time. Whenunplugging the unit, always grip theplug. Never pull the cord itself.

    Should any solid object or liquid getinto the system, unplug the system, andhave it checked by qualified personnelbefore operating it again. The AC power cord can be changed -only by a qualified service facility.On placement Do not place the system in an inclinedposition or in locations that areextremely hot, cold, dusty, dirty, orhumid or lacking adequate ventilation,or subject to vibration, direct sunlightor a bright light.

    Be careful when placing the unitor speakers on surfaces that havebeen specially treated (for example,with wax, oil, polish) as staining ordiscoloration of the surface may result.

    If the system is brought directlyfrom a cold to a warm location or isplaced in a very damp room, moisturemay condense on the lens inside theCD player, and cause the system tomalfunction. In this situation, removethe disc, and leave the system turnedon for about an hour until the moistureevaporates.

    On heat buildup Heat buildup on the unit duringoperation is normal and is not cause

    for alarm. Do not touch the cabinet if it has beenused continuously at a high volumebecause the cabinet may have become

    hot. Do not obstruct the ventilation holes.

    On the speaker systemThis speaker system is not magneticallyshielded, and the picture on nearbyTVsets may become magnetically distorted.In this situation, turn offthe TV, wait15 to 30 minutes, and turn it back on.If there is no improvement, move thespeakers far away from the TV.Cleaning the cabinetClean this system with a soft clothslightly moistened with a mild detergentsolution. Do not use any type of abrasivepad, scouring powder, or solvent, such asthinner, benzine, or alcohol.

    Bluetooth wirelesstechnologyBluetooth wireless technology is a shortrange wireless technology linking digitaldevices, such as personal computers anddigital still cameras. Using the Bluetoothwireless technology, you can operate theunits involved within a range of about 10meters.The Bluetooth wireless technology iscommonly used between two devices,but a single device can be connected tomultiple devices.You do not need wires to get connectedas you do with a USB connection, andyou do not need to place the devices faceto face as you do with wireless infraredtechnology. You can use the technologywith one Bluetooth device in your bagor pocket.Bluetooth wireless technology is a globalstandard supported by thousands ofcompanies. These companies produceproducts that meet the global standard.

    Effertive communication rangeBluetooth devices should be used withinapproximately 10 meters (unobstructeddistance) of each other. The effectivecommunication range may becomeshorter under the following conditions.- When a person, metal object, wallor other obstruction is between thedevices with a Bluetooth connection

    - Locations where a wireless LAN isinstalled- Around microwave ovens that are inuse- Locations where other electromagneticwaves occurEffects ofother devicesBluetooth devices and wireless LAN(IEEE 802.11big) use the same frequencyband (2.4 GHz). When using yourBluetooth device near a device withwireless LAN capability, electromagneticinterference may occur. This could resultin lower data transfer rates, noise, orinability to connect. If this happens, trythe following remedies:- Try connecting this system andBluetooth mobile phone or Bluetooth

    device when you are at least 10meters away from the wireless LANequipment.- Turn offthe power to the wireless LANequipment when using your Bluetooth'device within 10 meters.Effects on other devicesThe radio waves broadcast by this systemmay interfere with the operation of somemedical devices. Since this interferencemay result in malfunction, always turnoff the power on this system, Bluetoothmobile phone and Bluetooth device inthe following locations:- In hospitals, on trains, in airplanes,at gas stations, and any place whereflammable gasses may be present- Near automatic doors or fire alarms

    Notes This system supports security functions thatcomply with the Bluetooth specificationas a means of ensuring security during

    communication using Bluetooth technology.However, this security may be insufficientdepending on the setting contents andother factors, so always be careful whenperforming communication using Bluetoothtechnology. Sony cannot be held liable in any wayfor damages or other loss resulting frominformation leaks during communicationusing Bluetooth technology.

    Bluetooth communication is not necessarilyguaranteed with all Bluetooth devices thathave the same profile as this system.

    Bluetooth devices connected with this systemmust comply with the Bluetooth specificationprescribed by the BliJetooth SIG, Inc., andmust be certified to comply. However, evenwhen a device complies with the Bluetoothspecification, there may be cases wherethe characteristics or specifications of theBluetooth device make it impossible toconnect, or may result in different controlmethods, display or operation.

    Noise mayoccur or the audio maycut offdepending on the Bluetoothdevice connected with this system,the communications environment, orsurrounding conditions.
