2.1

General

Notes:

Only authorised persons should perform servicing of this 
module.

When using/handling this unit, pay special attention to the 
LCD Module: it should not be enforced into any other way 
then next rules, warnings, and/or cautions.

"Warning"

 indicates a hazard that may lead to death or

Safety Precautions

2.2.1

Warning 

Do not supply a voltage higher than specified to this 
product. This may damage the product or can create 
hazardous situations.

Do not use this product in locations where the humidity is 
extremely high, where it may be splashed with water, or 
where flammable materials surround it. 

Do not install or use the product in a location that does no 
satisfy specified environmental conditions. This may 
damage the product or can create hazardous situations. 

If a foreign substance (such as water, metal, or liquid) gets 
inside the product, immediately turn “OFF” the power. 
Continuing to use the product may cause electric shock or 
can create hazardous situations. 

If the product emits smoke and abnormal smell, or makes 
an abnormal sound, immediately turn “OFF” the power. 
Continuing to use the product may cause electric shock or 
can create hazardous situations. 

Do not (dis)connect the connector while power to the 
product is “ON”. It takes some time for the voltage to drop 
to a sufficiently low level after the power has been turned 
“OFF”. Confirm that the voltage has dropped to a safe level 
before (dis)connecting the connector. 

Do not pull out or insert the power cable from/to an outlet 
with wet hands. It may cause electric shock. 

If the power cable is damaged, or if the connector is loose, 
do not use the product, otherwise, this can lead to 
hazardous situations or may cause electric shock. 

The LCD Backlight Inverter unit uses a high voltage for the 
lamps. Keep the cautions concerning electric shock and do 
not touch the device circuitry handling the inverter unit. And 
because the capacitors of the device circuitry may remain 
charged at the moment of Power “OFF”, standing for 1 
minute is required in order to discharge the device circuitry.

2.2.2

Caution 

Do not place this product in a location that is subject to 
heavy vibration, or an unstable surface such as an inclined 
surface. The product may fall off or fall over, causing 
injuries.

Before disconnecting cable from the product, be sure to 
turn off the power. Be sure to hold the connector when 
disconnecting cables. Pulling a cable with excessive force 
may cause the core of the cable to be exposed or break the 
cable, and this can lead to fire or electric shock.

This product contains glass. If shock, vibration, heat or 
distortion is applied to the product, the glass may be 
broken.

If glass surface of the display breaks or is scratched, do not 
touched the broken pieces or the scratched with bare 
hands. You may be injured.

LCD Module requires to be handled with special care. LCD 
Module is not to be touched with metal or hard materials. 
Must not be stressed by heat or mechanical impact.

There are some particular components on the rear panel of 
this product. Skin contact with these components may 
cause an electric shock. So, handle with care.

While moving the product, be sure to turn off the power, 
disconnect all cables and watch your step. Dropping the 
product may cause injuries from electric shock. So, while 
moving the product handle with care.

When cleaning the panel is necessary, wipe it with a soft 
and moistened cloth a neural detergent. Caution on 
connector area. Do not use chemicals such as thinner or 
benzene.

LCD Module emits heat from the Lamp, Backlight lamp, 
and component parts. Therefore, the environmental 
temperature must not exceed 50 deg. C. LCD Module 
Backlight Inverter system is driven by high voltage, so it 
must avoid conductive materials.

If repairing components with a lead line, high voltage or 
high temperature components must be put out from a lead 
line and fix. 

Do not place an object on the surface of the display. The 
glass may break or be scratched. 

This product may be damaged if it is subject to excessive 
stresses (such as excessive voltage, current, or 
temperature). The absolute maximum ratings specify the 
limits of these stresses.

Do not cover or wrap with any covering materials while 
power is applied to the product.

This product is made from various materials such as glass, 
metal, and plastic. When discarding it, be sure to contact a 
purchase place.

If a discrepancy occurs due to any arbitrary modification or 
disassembly, supplier is not responsible for function, 
quality or other items.

Within the warranty period, general faults may be charged 
for depending on responsibility for the faults. You handle 
with care

2.3

Servicing Precautions

A colour TFT LCD Module can easily be damaged by both 
electrical and mechanical stresses. Users therefore, are 
requested to follow the “Servicing precautions of colour TFT 
LCD Module” on the following.

2.3.1

System Assembler

Follow the power sequence:

 An abnormal power 

sequence may cause critical malfunction or electrical 
damage.

Prevent physical stress.

Prevent overheat:

High temperatures on the surface of the screen may 
cause poor quality. Please use the LCD Module on the 
specified temperatures.

Low temperatures (under 10 deg. C) makes the LCD 
Module respond slowly, make the Backlight worse 
operated, and will shorten very much the lifetime 
accordingly.

Keep LCD Module dust-free

: The LCD Module is 

sensitive against dust; it can cause visual or functional 
problems.
