Unpacking Precautions
Some components on LCD-Kit05A are very sensitive to static
electric charges and can be damaged by a sudden rush of power.
Ground yourself to remove any static charge before touching your
LCD-Kit05A. You can do it by using a grounded wrist strap at all
times or by frequently touching any conducting materials that is
connected to the ground.
Do not touch the inner side of LCD panel and the connector/cable
of fluorescent lamp/backlight when the power is on. The inverter
supplies HIGH VOLTAGE to these parts (~ 630Vrms).
Disconnect power supply before handling and doing connection
on LCD-Kit05A. Do not plug any connector or jumper while the
power is on. It will cause fatal damage to your LCD panel.
Make sure that every connector is connected in correct direction.
Any incorrect connection may cause smoke or burn of electrical
parts or fatal damage of your LCD panel.
Be careful with the liquid crystal material. Do not swallow, inhale
or have skin contact with this material in case that the LCD panel
is broken and the liquid flow out. If you inhale the liquid material,
rinse your mouth immediately with water then go to see a doctor.
If you have skin contact with the liquid, wash it immediately with
alcohol. Be careful, too, with the chips of glass if the panel is
broken.
For outdoor usage, an ultra-violet ray protect-lens is
recommended to apply onto LCD display. It will prevent your LCD
from strong sun-light, scratches, dust and water invasion etc.
which can cause damage to the LCD display.
