Before operating the system, please 

read this manual thoroughly and retain 

it for future reference.

To reduce the risk of electrical shock, 

do not open the cabinet.

Refer servicing to qualified personnel 

only.

To reduce the risk of fire, do not cover 

the ventilation opening of the 

apparatus with newspapers, 

tablecloths, curtains, etc.

Do not place the naked flame sources 

such as lighted candles on the 

apparatus.

To reduce the risk of fire or electric 

shock, do not expose this apparatus to 

dripping or splashing, and do not place 

objects filled with liquids, such as 

vases, on the apparatus.

Do not install the appliance in a 

confined space, such as a bookcase or 

built-in cabinet.

As the main plug of AC power adaptor 

is used to disconnect the AC power 

adaptor from the mains, connect it to 

an easily accessible AC outlet.

Should you notice an abnormality in it, 

disconnect it from the AC outlet 

immediately.

The system is not disconnected from 

the mains as long as it is connected to 

the AC outlet, even if the system itself 

has been turned off.

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.

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.

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.

All countries/regions 100 V – 240 V AC, 

50/60 Hz

  Use only the supplied AC power 

adaptor.

  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.

  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.

Do not use alcohol, benzine or thinner 

to clean the cabinet.

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.
