any further.
• The AC power cord should be changed only at a
qualified service shop.
• For efficient heat dissipation, ensure there is sufficient
space to the rear of the subwoofer. Also, avoid
placing objects on the unit.
• Do not insert your hand or any objects into the hole
of the subwoofer and satellite speaker.
On operation
• Do not drive the speaker system with a continuous
wattage exceeding the maximum input power of the
system.
• Before connecting, turn off the speaker system, the
PC and audio component to avoid damaging the
speaker system.
• The volume level should not be turned up to the
point of distortion.
• 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
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 it off.
When there seems to be no improvement, locate the
system farther away from the TV set/personal
computer. Furthermore, be sure not to place objects in
which magnets are attached or used near the TV set/
personal computer, such as audio racks, TV stands, toys
etc. These may cause magnetic distortion to the picture
due to their interaction with the system.
