Disposal of waste 
batteries and electrical 
and electronic equipment 
(applicable in the 
European Union and 
other countries with 
separate collection systems)
This symbol on the product, the battery or on the 
packaging indicates that the product and the 
battery shall not be treated as household waste. 
On certain batteries this symbol might be used in 
combination with a chemical symbol. The 
chemical symbol for lead (Pb) is added if the 
battery contains more than 0.004% lead. By 
ensuring that these products and batteries are 
disposed of correctly, you will help to prevent 
potentially negative consequences for the 
environment and human health which could be 
caused by inappropriate waste handling. The 
recycling of the materials will help to conserve 
natural resources. In case of products that for 
safety, performance or data integrity reasons 
require a permanent connection with an 
incorporated battery, this battery should be 
replaced by qualified service staff only. To ensure 
that the battery and the electrical and electronic 
equipment will be treated properly, hand over 
these products at end-of-life to the appropriate 
collection point for the recycling of electrical and 
electronic equipment. For all other batteries, 
please view the section on how to remove the 
battery from the product safely. Hand the battery 
over to the appropriate collection point for the 
recycling of waste batteries. For more detailed 
information about recycling of this product or 
battery, please contact your local Civic Office, your 
household waste disposal service or the shop 
where you purchased the product or battery.
This equipment should be installed and operated 
keeping the radiator over 20 cm away from 
person’s body.
Precautions 
On safety 
• Should any solid object or liquid fall into the 
speaker system, unplug the speaker system and 
have it checked by qualified personnel before 
operating it any further.
• Do not climb on the speaker system, as you may 
fall down and injure yourself, or speaker system 
damage may result.
On power sources
• Before operating the speaker system, check that 
the operating voltage is identical to your local 
power supply. The operating voltage is indicated 
on the nameplate on the bottom of the bar 
speaker.
• If you are not going to use the speaker system 
for a long time, be sure to disconnect the 
speaker system from the wall outlet (mains). To 
disconnect the AC power cord (mains lead), 
grasp the plug itself; never pull the cord.
• One blade of the plug is wider than the other for 
the purpose of safety and will fit into the wall 
outlet (mains) only one way. If you are unable to 
insert the plug fully into the outlet, contact your 
dealer.
• The AC power cord (mains lead) must be 
changed only at a qualified service shop.
On heat buildup
Although the speaker system heats up during 
operation, this is not a malfunction.
If you continuously use this speaker system at 
high volume, the speaker system temperature at 
the rear and bottom rises considerably. To avoid 
burning yourself, do not touch the speaker 
system.
On placement
• Place the speaker system in a location with 
adequate ventilation to prevent heat buildup 
and prolong the life of the speaker system.
• Do not place the speaker system near heat 
sources or in a place subject to direct sunlight, 
excessive dust, or mechanical shock.
• Do not place anything on the top of the bar 
speaker.
• If the speaker system is being used in 
combination with a TV, VCR, or tape deck, noise 
may result and picture quality may suffer. In 
such a case, place the speaker system away 
from the TV, VCR, or tape deck.
• Use caution when placing the speaker system 
on a surface that has been specially treated 
(with wax, oil, polish, etc.), as staining or 
discoloration of the surface may result.
• Take care to avoid any possible injury from the 
corners of the bar speaker.
On operation
Before connecting other equipment, be sure to 
turn off and unplug the speaker system.
If you encounter color irregularity on a 
nearby TV screen
Color irregularities may be observed on certain 
types of TV.
• If color irregularity is observed... 
Turn off the TV, then turn it on again after 15 to 
30 minutes.
• If color irregularity is observed again... 
Place the speaker system further away from the 
TV.
On cleaning
• Clean the speaker system with a soft, dry cloth. 
Do not use any type of abrasive pad, scouring 
powder, or solvent such as alcohol or benzine.
If you have any questions or problems concerning 
your speaker system, please consult your nearest 
Sony dealer.
