SRS-A45

Precautions

•Operate the system only on 9 V DC when using batteries.

For AC operation, use only the supplied AC power adaptor. Do not use any other AC power adaptor.

•After operating the system with the AC power adaptor, disconnect the AC power adaptor from the wall outlet if the system is not to be used for an extended period of time. The POWER switch on the system does not turn the AC power adaptor off.

•If the system is not to be used for a long period of time or is to be operated extensively on AC power, remove the batteries to avoid damage caused by battery leakage and corrosion.

•Do not open the cabinet. Refer servicing to qualified personnel only.

•Do not leave the system in a location near heat sources, or in a place subject to direct sunlight, excessive dust, moisture, rain or mechanical shock.

•Should any solid object or liquid fall into the system, remove the batteries and have the system checked by qualified personnel before operating it any further.

•Do not use alcohol, benzine or thinner to clean the cabinet.

•Although this system is magnetically shielded, do not leave recorded tapes, watches, personal credit cards or floppy disks using magnetic coding in front of the system for an extended period of time.

If the TV picture or monitor display is magnetically distorted

Although this system is magnetically shielded, there may be cases that the picture on some TV sets/ personal computer sets may become magnetically distorted. In such a case, turn off the power of the TV set/personal computer set once, and after 15 to 30 minutes turn it on again. For the personal computer set, take the appropriate measures such as data storage before turning it off.

When there seems to be no improvement, locate the system further away from the TV set/personal computer set. Furthermore, be sure not to place objects in which magnets are attached or used near the TV set/personal computer set, such as audio racks, TV stands, toys, etc. These may cause magnetic distortion to the picture due to their interaction with the system.

If you have any questions or problems concerning your system that are not covered in this manual, please consult your nearest Sony dealer.
