Precautions On safety
The nameplate is located on the bottom exterior of the left speaker.

• Before operating the system, be sure that the operating voltage of the system is identical to that of your local power supply.

• Use only the supplied AC power adaptor.

Precautions On operation

• Should any solid object or liquid fall into the system, have the system checked by qualified personnel before operating it any further.
• Although the satellite speakers are magnetically shielded, the subwoofer is not, so do not leave recorded tapes, watches, personal credit cards, or floppy disks with magnetic coding in front of the system for an extended period of time.

On placement

• Do not set the system in an inclined position.
• 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.

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

If the TV picture or monitor display is magnetically distorted when placed near this system

Although the satellite speakers are magnetically shielded, the subwoofer is not, and there may be cases that the picture on some TV sets/personal computers may become magnetically distorted. In such a case, turn off the power of the TV set/personal computer once, and after 15 to 30 minutes turn it on again. In the case of a personal computer, take appropriate measures such as data storage before turning off.
If no improvement is apparent, locate the system farther away from the TV set/personal computer.

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

2. Connect the system to a source device.
   Refer to the operating instructions supplied with each connected device for details.

When the system is connected to the monaural jack of a source device
The sound may not come through the right speaker.

Notes
If connecting the system via a device with a built-in radio or tuner, radio broadcasts or TV sound may not be received, or sensitivity may be reduced significantly.

• If the PC volume adjustment (master volume, WAV volume, etc.) is low, sound may be insufficient. If so, turn up the sound of the PC. For details on volume adjustment on your PC, refer to its operating instructions.
• Make sure the connection of the stereo mini plug and the jack of the source device is made properly. (See fig. D)
  
• Make sure the left speaker is properly connected to the right speaker and subwoofer. If you connect incorrectly, low tone may not be produced by the subwoofer, or the sound of the right speaker may be distorted. Discontinue use, as malfunction may result.
• Be sure to lower the volume of the source device (PC, TV, etc.) and turn off the system when removing the audio cable from the source device. If you remove the audio cable while the source device (PC, TV, etc.) is working, the equipment or your ears may be damaged by unexpected loud sound.

Listening to the sound

First, turn down the volume on this system. When connecting the system to the headphones output, turn down the volume of the source device.

1. Press the button to turn on.
   The power indicator lights up.
2. Start playback of the source device.
3. Adjust the volume.
   VOLUME control: Adjusts the overall volume.
   BASS control: Adjusts the low tone. Set the bass volume to an undistorted level to prevent system damage.
   TREBLE control: Adjusts the high tone.

To turn off the system
Press the button. The power indicator goes off.

To use the headphones/ earphones
Connect them to the PHONES jack.

Notes

• If the source device has a bass boost function or equalizer function, set to off. If these functions are on, sound may be distorted.
• If headphones/earphones are connected, the bass and treble control function does not work.
• If the system volume, bass and treble level is high, depending on the volume setting of the connected device or the volume setting of the software on PC, speaker sound may be muted. This is caused by the protection circuit, and not a malfunction. Turn down the volume, bass and treble accordingly, in this case.

About the Auto Power function

If no signal is input for about 25 minutes or more, the system turns off automatically. When the button is in the ON (pushed) position and a signal is input, the system turns on automatically. This function may not work depending on how the system is used.

Notes

• If the input signal level is too low, the system will not turn on automatically.
• If a device that generates microwaves, such as a mobile phone, is nearby, the system may be turned on unintentionally by the device.
• If a mobile phone is connected to the system, the system may be turned on unintentionally by noise or an incoming call. When connecting a mobile phone, turn on/off the system manually by the button.
• The system may not turn off automatically because of received noise, depending on the source device.
• If no device is connected, the system may not turn off automatically, or it may turn on unintentionally.
• The beginning of the input signal may not be heard, depending on the input signal level.
• Until the system receives an input signal and turns on automatically, no sound will be heard.
• When leaving the system unattended, press the button to OFF to prevent malfunction.
• If the power is turned off automatically, the button remains in the ON (pushed) position, but the power indicator turns off. The system will turn on again automatically when an input signal is received, and the power indicator will turn on. You can manually turn on again by turning the system off and then on again.

Troubleshooting

Should you experience any problems with your speaker system, check the following list and take the suggested measures. Also refer to the operating instructions supplied with each connected device for details about connection. If the problem persists, consult your nearest Sony dealer.

No sound / Low sound level

• Check that both this system and the source device are turned on.
• Turn up the volume of the system.
• Turn up the volume of the source device as high as possible before the onset of distortion. For details on volume adjustment, refer to the operating instructions supplied with the device.
• Make sure all connections have been correctly made. If the audio cable (stereo mini) (supplied) is connected to the audio out jack, the sound level may be low. Connect to the headphones (stereo-mini) jack, in this case.
• If the mute function of the volume adjustment of your PC is set, cancel it.
• Check if headphones are connected. If they are, disconnect them. 
• Disconnect the audio cable from the system and PC or source device, then firmly reconnect.
• Ensure that your PC sound balance is set to the center.
• If the source device is connected to both the INPUT 1 (Stereo mini) and INPUT 2 jacks, volume may be attenuated. In this case, disconnect either one of the jacks.

Distorted sound

• Turn down the volume of the source device to the point where the sound is no longer distorted. For details on volume adjustment, refer to the operating instructions supplied with the device.
• If the source device has a bass boost function, set it to off.
• Turn down the volume of the system.
• Make sure all connections have been correctly made. If an audio cable for the audio out jack (not supplied) is connected to the headphones (stereo-mini) jack, sound may be distorted. Connect to the audio out jack, in this case.

There is hum or noise in the system output

• Make sure all connections have been correctly made.
• Make sure no audio devices are positioned too close to the TV set.

There is noise in the sound from a PC

If the source device is a PC, connect the audio cable (stereo mini) (supplied) to the headphone jack of the main unit of the PC, not to the monitor of the PC.

The sound comes through only one satellite speaker

If connecting the system to the monaural jack of a source device, the sound may come through only one satellite speaker.

When connected to a TV, the system does not turn off automatically

If the audio cable (stereo mini) (supplied) is connected to the headphone jack of the TV, the Auto Power function may not work depending on the TV model. In this case, disconnect the audio cable, and then connect the audio out jack of the TV and the INPUT 2 jack of this system with a suitable audio cable (not supplied).

TV startup sound is heard from the system

When listening to TV sound, turn on the power of the TV first, and then turn the system on.
