Important Safety Notice

1. Safety precautions

This monitor is manufactured and tested on a ground principle that a user’s safety comes first.

However, improper used or installation may cause damage to the monitor as well as to the user.

Warning:

This monitor should be operated only at the correct power sources indicated on the label on the

rear of the monitor. If you’re unsure of the power supply in you residence, consult your local dealer

or Power Company.

Do not try to repair the monitor by yourself, as it contains no user-serviceable parts. This monitor

should only be repaired by a qualified technician.

Do not remove the monitor cabinet. There are high-voltage parts inside that may cause electric

shock to human bodies.

Stop using the monitor if the cabinet is damaged. Have it checked by a service technician.

Put your monitor only in a lean, cool, dry environment. If it gets wet, unplug the power cable

immediately and consult your closed dealer.

Always unplug the monitor before cleaning it. Clean the cabinet with a clean, dry cloth. Apply

non-ammonia based cleaner onto the cloth, not directly onto the class screen.

Do not place heavy objects on the monitor or power cord.

2. Product safety notice

Many electrical and mechanical parts in this chassis have special safety visual inspections and the

protection afforded by them cannot necessarily be obtained by using replacement components rated

for higher voltage, wattage, etc. Before replacing any of these components read the parts list in this

manual carefully. The use of substitute replacement parts, which do not have the same safety

characteristics as specified in the parts list, may create shock, fire, or other hazards.

3. Service notes

When replacing parts or circuit boards, clamp the lead wires around terminals before soldering.

Keep wires away from high voltage, high temperature components and sharp edges.

Keep wires in their original position so as to reduce interference.

Adjustment of this product please refers to the user’ manual.

Note 6

Note: The waveform of the voltage output of inverter must be area-symmetric and the design of the

inverter must have specifications for the modularized lamp. The performance of the Backlight,

such as lifetime or brightness, is greatly influenced by the characteristics of the DC-AC inverter

for the lamp. All the parameters of an inverter should be carefully designed to avoid producing too

much current leakage from high voltage output of the inverter. When designing or ordering the

inverter please make sure that a poor lighting caused by the mismatch of the Backlight and the

inverter (miss-lighting, flicker, etc.) never occurs. If the above situation is confirmed, the module

should be operated in the same manners when it is installed in your instrument.

Note 2: Test equipment: AS-114B

Note 3: The voltage shown above should be applied to the lamp for more than 1 second after startup.

Otherwise, the lamp may not be turned on normally.

Note 4: Inverter should provide more than min. value, and then lamp could be completely turned on.

Note 5:Lamp frequency may produce interference with horizontal synchronous frequency and this

may cause line flow on the display. Therefore lamp frequency shall be detached from the

horizontal synchronous frequency and its harmonics as far as possible in order to avoid

interference.

Note 6:Lamp life definition: The brightness of lamp becomes 50% of the initial brightness or not

normal lighting.

E. Safety

1. Sharp Edge Requirements

There will be no sharp edges or corners on the display assembly that could cause injury.

2. Materials

a. Toxicity

There will be no carcinogenic materials used anywhere in the display module. If toxic materials

are used, they will be reviewed and approved by the responsible InnoLux Toxicologist.

b. Flammability

All components including electrical components that do not meet the flammability grade UL94-V1

in the module will complete the flammability rating exception approval process. The printed circuit

board will be made from material rated 94-V1 or better. The actual UL flammability rating will be

printed on the printed circuit board.

c. Capacitors

If any polarized capacitors are used in the display assembly, provisions will be made to keep

them from being inserted backwards.

F. Display quality

The display quality of the color TFT-LCD module should be in compliance with the

Innolux’s Incoming inspection standard.

G. Handling precaution

The Handling of the TFT-LCD should be in compliance with the Innolux’s handling principle

standard.
