Precautions
On safety
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.
Where purchased
Operating voltage
U.S.A./Canada
120 V AC, 60 Hz
European countries
220 – 230 V AC, 50 Hz
Other countries
• 110 – 120 V AC, 50/60 Hz
• 220 – 230 V AC, 50 Hz
• Use only the optional AC power adaptor AC-E60HG.
• 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.
On operation
• Do not open the cabinet. Refer servicing to qualified
personnel only.
• Should any solid object or liquid fall into the system,
have the system checked by qualified personnel
before operating it any further.
• Although this system is magnetically shielded, do
not leave recorded tapes, watches, personal credit
cards, or floppy disks with 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
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.
On placement
• Do not set the speakers in an inclined position.
• Do not leave the system in a location near heat
sources, or in a place subject to direct sunlight,
excessive dust, moisture, rain or mechanical shock.
