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 usage or installation may cause damage to the monitor as well as to the user.
Warnings:

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 is 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 object 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's manual.

b. Display color vs. input data signals
The brightness of each primary color (red, green and blue) is based on the 8-bit gray scale data input
for the color; the higher the binary input, the brighter the color. The table below provides a reference for
color versus data input.

Frequency F 40 - 60 KHZ Note 5
Lamp lifetime 50,000 - - Hrs 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 1: The degree of unbalance: less than 10%
The ratio of wave height: less than 2 10%




Ip Ip: high side peak


I-p I-p: low side peak

The degree of unbalance = |Ip-I-p| /Irms*100(%)
The ratio of wave height = Ip (or I-p)/Irms
Lamp should be completely turned on.

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 max. 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: Life time (Hr) is defined as the time when brightness of a lamp unit itself becomes 50% or less
than its original value at the condition of Ta = 252C and IL = 7.5mArms.
