1.SAFETY PRECAUTION
3
USE SET VOLTAGE.
- AC 100 ~ 240V (1.2A / 50~60㎐)
- DC 12 ~ 24V (MAX 6A)
SAFETY PRECAUTION ABOUT PARTS
- Some parts of this product should be handled with
cauon. User can find those parts in a circuit diagram
and part list.
Do not use aachments not recommended by the
manufacturer. Use of inadequate aachment can result
in accidents.
- Drawing can’t be revised without TVLogic’s permission.
- Use screw holes on the corner when installing the
LCD module.
- Do not push the panel or frame and do not cause an
electric shock to protect the product from damages.
- When handling the LCD module, put an wrist band
to avoid the LCD module from stac electricity
which may cause damages to the electric
components.
- Do not leave the product in a hot or humid place for
a long me.
- Keep the LCD module away from direct rays of the
Sun-light.
- Keep away the product from water because it’s the
reason for short circuit and reducing life span of
electric components.
- Use socloths to wipe the surface of LCD module
when it gets dirty.(Do not use coarse cloths which
might cause damages to the LCD module.)
-If the product is exposed to water, you must wipe
the device with a dry cloth then dissemble the
device to dry.
SAFETY PRECAUTIONS ABOUT DISASSEMBLY
- Please use soft cloths or cushioned sponge
when you disassemble or assemble the
products.
- To separate the panel, release the screws
on the four corners then slowly lift up the
panel while removing the panel interface
cable.
- To separate the board, remove the cable
from it first, remove the bolt which is
holding down the board then separate.
Make sure the cable pin is firmly connected
to the connector while doing it.
SAFETY PRECAUTIONS ABOUT ASSEMBLY
- Please set torque at 2K of electronic screw
driver when you assemble LCD panel and
cases in order to avoid damages of screw
holes of case. This might cause changing
of whole case if you use over torque of
electronic screw driver.
- The connector should be handled with
caution because it is thin and weak. Wrong
connection causes malfunction of the
board and the panel.
WARNING
BE CAREFUL OF THE ELECTRIC SHOCK!
- Make sure to disconnect the adapter from
the AC power when replacing CCFL or
inverter circuit because high voltage about
650Vrms flows in inverter circuit.
- Do not make the cover of cables damaged
in order to avoid accidents such as a fire

use over torque of electronic screw driver.
- The connector should be handled with cauon as it
is thin and fragile. Wrong connecon causes
malfuncon of the board and the panel.
WARNING
BEWARE OF ELECTRIC SHOCKS!
- Make sure to disconnect the adapter from the AC
power when replacing CCFL or the inverter circuit
because high voltage of about 650 Vrms flows in the
inverter circuit.
- Do not make the cover of cables damaged in order
to avoid accidents such as fire or electric shocks.
All the cables in the inverter circuit must be
handled with cauon.
