Important Safety Precautions
CAUTION
Risk of electric shock! Do not open speakers or immerse them in any liquid!
IMPORTANT OPERATING INSTRUCTIONS
Read carefully!
• Water and moisture – Do not use the speakers near water
(e.g., bathtub or swimming pool), and do not immerse them in any
liquid or pour any liquid on them.
• Heat – Place the speakers away from all heat sources.
• Ventilation – Do not block the openings in the speaker cabinets,
never push objects into speaker vents or slots because of fire
or electric shock hazards, and provide sufficient space around
the speakers for proper ventilation.
• Location – Place the speakers in a stable location so they will not fall
causing damage to the speakers or bodily harm.
• Connections – Operate the speakers only from the audio line out
jack of the computer or of an audio device.
• Cleaning – Unplug the speakers from the computer and from
the electrical outlet before cleaning them with a damp cloth.
• Lightning – For added protection during lightning storms, unplug
the speakers from the electrical outlet and turn off the computer.
• Servicing – Do not attempt to service the speakers yourself by
opening the speaker cabinets, which may expose you to dangerous
voltage or shock hazards. Refer all servicing to qualified service
personnel.
Placement
• The subwoofer and satellite speakers are magnetically shielded,
and can be placed next to the computer monitor without affecting
screen images.
• Put the subwoofer either on your desktop, as shown in the diagram,
or on the floor beneath your table top.
• The best stereo effect is usually obtained by placing the satellite
speakers at an equal distance from each other and the listener.
• For optimum performance, angle the satellite speakers slightly
toward the listening position.
Connections
1. Turn the volume control all the way down on the remote control unit.
2. Connect the left speaker to the “ Left ” connection on the subwoofer.
3. Connect the right speaker to the “ Right ” connection on the
subwoofer.
4. Connect the remote control unit to “ Remote ” on the subwoofer.
5. Connect the subwoofer to the computer.
6. Connect the power adapter to the “ DC ” jack on the subwoofer,
then plug the power adapter into an electrical outlet.

the volume control on the volume control unit. Also adjust the Bass
control on the subwoofer.
Operation

• To increase the volume, rotate the volume control up on
the remote control unit. To decrease the volume, rotate the volume
