Additional Information
Safety Information
Installation/Set-up
Install and use the TV set in accordance with 
the instructions below in order to avoid any 
risk of fire, electrical shock or damage and/or 
injuries.
Installation
• The TV set should be installed near an 
easily accessible AC power outlet.
• Place the TV set on a stable, level surface 
to avoid it from falling down and cause 
personal injury or damage to the TV.
• Only qualified service personnel should 
carry out wall installations.
• For safety reasons, it is strongly 
recommended that you use Sony 
accessories, including:
Wall-mount bracket
SU-WL100 (KDL-26/22EX42x)
SU-WL50B (except 
KDL-26/22EX42x)
• Be sure to use the screws supplied with the 
Wall-mount bracket when attaching the 
mounting hooks to the TV set. The 
supplied screws are designed so that they 
are 8 mm to 12 mm in length when 
measured from the attaching surface of the 
mounting hook. 
The diameter and length of the screws 
differ depending on the Wall-mount 
bracket model. 
Use of screws other than those supplied 
may result in internal damage to the TV set 
or cause it to fall, etc.
Transporting
• Before transporting the TV set, disconnect 
all cables.
• Two or more people are needed to 
transport a large TV set.
• When transporting the TV set by hand, 
hold it as shown below. Do not put stress 
on the LCD panel and the frame around the 
screen.
• When transporting the TV set, do not 
subject it to jolts or excessive vibration.
• When transporting the TV set for repairs or 
when moving, pack it using the original 
carton and packing material.
Ventilation
• Never cover the ventilation holes or insert 
anything in the cabinet.
• Leave space around the TV set as shown 
below.
• It is strongly recommended that you use a 
Sony wall-mount bracket in order to 
provide adequate air-circulation.
Installed on the wall
Installed with stand
• To ensure proper ventilation and prevent 
the collection of dirt or dust:
Do not lay the TV set flat, install 
upside down, backwards, or 
sideways.
Do not place the TV set on a shelf, 
rug, bed or in a closet.
Do not cover the TV set with a cloth, 
such as curtains, or items such as 
newspapers, etc.
Do not install the TV set as shown 
below.
AC power cord
Handle the AC power cord and outlet as 
follows in order to avoid any risk of fire, 
electrical shock or damage and/or injuries:
Use only Sony supplied AC power cords, 
not those of other brands.
Insert the plug fully into the AC power 
outlet.
Operate the TV set on a 110–240 V AC 
supply only.
When wiring cables, be sure to unplug 
the AC power cord for your safety and 
take care not to catch your feet on the 
cables.
Disconnect the AC power cord from the 
AC power outlet before working on or 
moving the TV set.
Keep the AC power cord away from heat 
sources.
Unplug the AC power plug and clean it 
regularly. If the plug is covered with dust 
and it picks up moisture, its insulation 
may deteriorate, which could result in a 
fire. 
Notes
• Do not use the supplied AC power cord on 
any other equipment.
• Do not pinch, bend, or twist the AC power 
cord excessively. The core conductors may 
be exposed or broken.
• Do not modify the AC power cord.
• Do not put anything heavy on the AC 
power cord.
• Do not pull on the AC power cord itself 
when disconnecting the AC power cord.
• Do not connect too many appliances to the 
same AC power outlet.
• Do not use a poor fitting AC power outlet.
Prohibited Usage
Do not install/use the TV set in locations, 
environments or situations such as those 
listed below, or the TV set may malfunction 
and cause a fire, electrical shock, damage 
and/or injuries.
Location:
Outdoors (in direct sunlight), at the 
seashore, on a ship or other vessel, inside a 
vehicle, in medical institutions, unstable 
locations, near water, rain, moisture or 
smoke.
If the TV is placed in the changing room 
of a public bath or hot spring, the TV may 
be damaged by airborne sulfur, etc.
For best picture quality, do not expose the 
screen to direct illumination or sunlight.
Avoid moving the TV from a cold area to 
a warm area. Sudden room temperature 
changes may cause moisture 
condensation. This may cause the TV to 
show poor picture and/or poor colour. 
Should this occur, allow moisture to 
evaporate completely before powering the 
TV on.
