• Be careful not to apply force on the conductor when soldering

 or unsoldering.

• Never reuse a disconnected chip component.

Note on the AC power adaptor
Use only the supplied AC power adaptor. Do not use
any other AC power adaptor to avoid damaging the
speakers.

The nameplate indicating operating voltage, power
consumption, etc., is located on the rear exterior.
• Before operating the system, be sure that the

operating voltage of the system is identical with that
of your local power supply.

U.S.A./Canada

120 V AC, 60 Hz

Other countries

• 110 – 120 V AC, 50/60 Hz
• 220 – 230 V AC, 50 Hz

• Use only the supplied AC power adaptor.
• After operating the system with the AC power

adaptor, disconnect the AC power adaptor from the
wall outlet if the system is not to be used for an
extended period of time. The POWER switch does
not turn the AC power adaptor off.

Although this system is magnetically shielded, there
may be cases that the picture on some TV sets/personal
computer sets may become magnetically distorted. In
such a case, turn off the power of the TV set/personal
computer set once, and after 15 to 30 minutes turn it on
again. For the personal computer set, take the
appropriate measures such as data storage before
turning it off.
When there seems to be no improvement, locate the
system further away from the TV set/personal
computer set. Furthermore, be sure not to place objects
in which magnets are attached or used near the TV set/
personal computer set, such as audio racks, TV stands,
toys etc. These may cause magnetic distortion to the
picture due to their interaction with the system.
