Please read the following instructions carefully:
1. Remove the plugs from the sockets before cleaning the
speakers. Do not use liquid cleaning agents or spray cans. Wipe
off the speakers with a damp cloth.
2. Do not u se the speakers near water, for example, near a bathtub,
washbowl, a kitchen sink or wash basin, in a damp cellar, at a
swimming pool etc.
3. Make sure there is nothing on the power cable. Do not place the
speakers in a place where the cable can be subject to wear or
can be damaged by persons treading on it.
4. Never insert any object into one of the slots in the housing of the
speaker as this object may touch dangerous live components or
parts, which could result in a fire or an electric shock.
5. Never attempt to repair the speakers your self. If you open or
remove the housing, you may come into contact with high-voltage
components or face other hazards. The speakers should only be
serviced by specially trained personnel.
6. Remove the plug from the socket under the following conditions,
and have the speakers repaired by specially trained pers onnel:
a) the cable or the pl ug has been damaged or worn;
b) liquid has been spilled into the speakers;

3. Connection
The speakers are eas y to connect since all cables are supplied. Follow
the instructions as shown in Figure 1.
With most computers the best sound is delivered by using your
computer’s “LINE-OUT” output. If your computer does n o t have a
“LINE-OUT” output or if the sound is too poor, use the “SPEAK”
output.

2. Have your computer produce some sound (for example, by
playin g a CD).
3. Adjust the sound using the following controls:
a) Volume control
b) Bass control (amount of low-frequency sound)
c) Treble control (amount of high-frequency sound)
d) 3D control (increases the stereo effect of the sound,
particularly useful if the speakers are positioned close to each
other).
