Note
This equipment has been tested and
found to comply with the limits for a
Class B digital device, pursuant to Part
15 of the FCC Rules. These limits are
designed to provide reasonable
protection against harmful interference
in a residential installation. This
equipment generates, uses and can
radiate radio frequency energy and, if
not installed and used in accordance
with the instructions, may cause
harmful interference to radio
communications. However, there is no
guarantee that interference will not
occur in a particular installation. If this
equipment does cause harmful
interference to radio or television
reception, which can be determined by
turning the equipment off and on, the
user is encouraged to try to correct the
interference by one or more of the
following measures:
– Reorient or relocate the receiving
antenna.
– Increase the separation between the
equipment and receiver.
– Connect the equipment into an
outlet on a circuit different from that
to which the receiver is connected.
– Consult the dealer or an experienced
radio/TV technician for help.
CAUTION
You are cautioned that any changes or
modifications not expressly approved
in this manual could void your
authority to operate this equipment.
This Class B digital apparatus complies
with Canadian ICES-003.
Precautions
On safety
The nameplate is located on the
bottom exterior of the left speaker.
Before operating the system, be sure
that the operating voltage of the
system is identical to that of your
local power supply.
Where purchased Operating voltage
All countries/regions 100 V – 240 V AC,
50/60 Hz
Use only the supplied AC power
adaptor.
On operation
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.
On placement
Do not set the system 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.
On cleaning
Do not use alcohol, benzine or thinner
to clean the cabinet.
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 off.
If no improvement is apparent, 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, such as
audio racks, TV stands, toys, etc., near
the TV set/personal computer. These
may cause magnetic distortion to the
picture due to magnetic interaction.
If you have any questions or problems
concerning this system that are not
covered in this manual, please consult
your nearest Sony dealer.
