Connect the AC power adaptor to the DC IN 12V jack.
Notes on the AC power adaptor

• Use only the supplied AC power adaptor. To avoid damaging the system do not use any other AC power adaptor.
  
  Polarity of the plug
• Plug the AC power adaptor into a nearby AC output. In the case of a problem, unplug from the AC outlet immediately.
• Do not place the AC power adaptor on a bookshelf or in a confined place, such as a cabinet.
• To avoid fire or electric shock do not use the AC power adaptor in a place subject to liquid or moisture. Furthermore, do not place liquidfilled vessels, such as vases, etc., on the AC power adaptor.

Hooking up the system

(See fig. C)

1. Connect the satellite speakers (L/R) to the subwoofer.
   Either satellite speaker can be used for the right and left channels. When connecting to the subwoofer, the speaker connected to the Rch jack outputs the right channel sound, and the speaker connected to the Lch jack outputs the left channel sound.
   Set the satellite speaker connected to the Rch jack to your right, and set the satellite speaker connected to the Lch jack to your left.
2. Connect the system to a source device.
   Use the audio cable to connect.

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

• 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 audio cable and the jack of the source device is made properly.
• 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 you remove the audio cable while the source device (PC, etc) is working, the equipment or your ears may be damaged by unexpected loud sound. Be sure to lower the volume of the source device (PC, etc) and turn off the system when removing the audio cable from the source device.

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 of the subwoofer.
4. Press the button to turn off after use.
   The power indicator goes off.

To adjust the bass volume level
Turn the BASS control on the subwoofer to adjust the bass volume. Set the bass volume to an undistorted level to prevent system damage.
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.
• Although this system is designed to be used with a PC or a portable audio device, if the system volume and the bass volume are high, depending on the volume setting, the operating software, and the devices being connected, the satellite speaker sound may be paused. This is caused by the protection circuit, and it's not a malfunction. Turn down the volume and the bass volume during use.

Turning the system on/off automatically

How the Auto Power function works

• This feature is only available when the button is in the ON position.
• If a signal is input, the system turns on automatically.
• If no signal is input for about 25 minutes or more*, the system turns off automatically.

* This may vary according to 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.
• When leaving the system unattended, press the button to OFF to prevent malfunction.
• If the power is turned off automatically, the button remains on, but the power indicator turns off. The system turns on automatically after receiving an input signal (such as a music signal), and then the power indicator turns on. Even with no input signal (e.g., music signal), you can turn on by turning off and then on again. If no signal is input for about 25 minutes or more, the system turns off automatically again.
