Some electronic parts/components would fail or malfunction at a certain rate. In spite of every effort to
enhance reliability of products by NEC, the possibility of failures and malfunction might not be avoided
entirely. To prevent the risks of damage to death, human bodily injury or other property arising out
thereof or in connection therewith, each customer is required to take sufficient measures in its safety
designs and plans including, but not limited to, redundant system, fire-containment and anti-failure.
The products are classified into three quality grades: "Standard", "Special", and "Specific" of the
highest grade of a quality assurance program at the choice of a customer. Each quality grade is designed
for applications described below. Any customer who intends to use a product for application other than
that of Standard quality grade is required to contact an NEC sales representative in advance.
The Standard quality grade applies to the products developed, designed and manufactured in
accordance with the NEC standard quality assurance program, which are designed for such application as
any failure or malfunction of the products (sets) or parts/components incorporated therein a customer uses
are, directly or indirectly, free of any damage to death, human bodily injury or other property, like general
electronic devices.
Examples: Computers, office automation equipment, communications equipment, test and measurement
equipment, audio and visual equipment, home electronic appliances, machine tools, personal
electronic equipment, industrial robots, etc.
The Special quality grade applies to the products developed, designed and manufactured in accordance
with an NEC quality assurance program stricter than the standard one, which are designed for such
application as any failure or malfunction of the products (sets) or parts/components incorporated therein a
customer uses might directly cause any damage to death, human bodily injury or other property, or such
application under more severe condition than that defined in the Standard quality grade without such
direct damage.
Examples: Control systems for transportation equipment (automobiles, trains, ships, etc.), traffic control
systems, anti-disaster systems, anti-crime systems, medical equipment not specifically
designed for life support, safety equipment, etc.
The Specific quality grade applies to the products developed, designed and manufactured in accordance
with the standards or quality assurance program designated by a customer who requires an extremely
higher level of reliability and quality for such products.
Examples: Military systems, aircraft control equipment, aerospace equipment, nuclear reactor control
systems, medical equipment/devices/systems for life support, etc.
The quality grade of this product is the "Standard" unless otherwise specified in this document.

Note1: When designing of the power supply, take the measures for the prevention of surge voltage.
Note2: The power supply lines (VDDB and GNDB) have large ripple voltage during luminance
control of LCD lamps. There is the possibility that the ripple voltage produces acoustic noise
and signal wave noise in audio circuit and so on. Put a capacitor (5,000 to 6,000μF) between
the power supply lines (VDDB and GNDB) to reduce the noise, if the noise occurred in the
circuit.

occur.

2.6 LUMINANCE CONTROL
Method
Adjustment and luminance ratio
• Adjustment
The variable resistor (R) for luminance control should be 10kΩ ±5%, 1/10W. Minimum
point of the resistor is the minimum luminance. Also maximum point of the resistor is the
maximum luminance.
The resistor (R) must be connected between BRTH-BRTI terminals.

• Adjustment
Voltage control method works, when BRTH terminal is 0V and VBI voltage is input
between BRTI and BRTH terminal. This control method can carry out continuation
adjustment of luminance.
Luminance is the maximum when BRTI terminal is Open.

4. PRECAUTIONS
4.1 MEANING OF CAUTION SIGNS
The following caution signs have very important meaning. Be sure to read "4.2 CAUTIONS" and
"4.3 ATTENTIONS", after understanding these contents!
!
This sign has the meaning that customer will be injured by himself or the product will
sustain a damage, if customer has wrong operations.
This sign has the meaning that customer will get an electrical shock, if customer has
wrong operations.
This sign has the meaning that customer will be injured by himself, if customer has
wrong operations.
4.2 CAUTIONS
∗ Do not touch the inverter while the inverter is working, because there is a danger
of an electric shock.
∗ Do not remove the inverter protection sheet, because there is a danger of an
electrical shock.
∗ Be sure to wait some time after turning power OFF before starting replacement
work, because the inverter is charged at a high voltage after working.
∗ Be sure to wait some time after turning power OFF before starting replacement
work, because the inverter is hot after working.
∗ Do not shock the inverter, because there is a danger of breaking.
4.3 ATTENTIONS
!
4.3.1 Handling of the product
① Take hold of both ends without touching the circuit board when the product (INVERTER) is
picked up from inner packing box to avoid broken down or misadjustment, because of stress to
mounting parts on the circuit board.
② When handling the product, take the measures of electrostatic discharge with such as earth band,
ionic shower and so on, because the product may be damaged by electrostatic.
③ Do not push nor pull the interface connectors while the product is working.
④ Do not hook nor pull cables such as lamp cable, and so on, in order to avoid any damage.
⑤ Properly connect the adaptable plug (backlight side) to socket (inverter side) without incomplete
connection. After connecting, be careful not to hook the lamp cables because incomplete
connection may occur by hooking the lamp cables. This incomplete connection may cause
abnormal operation of high voltage circuit.
⑥ Adaptable LCD modules of the product has cold cathode fluorescent lamps. After the product is
stored under condition of low temperature or dark place for a long time, the cold cathode
fluorescent lamp may not be turned on under the same condition because of the general
characteristic of cold cathode fluorescent lamp. In addition, when Luminance control ratio is low,
the lamp may not be turned on. In this case, power should be supplied again.

4.3.2 Environment
① Do not operate or store in high temperature, high humidity, dewdrop atmosphere or corrosive
gases. Keep the product in packing box with antistatic pouch in room temperature to avoid dusts
and sunlight, when storing the product.
② In order to prevent dew condensation occurring by temperature difference, the product packing
box should be opened after enough time being left under the environment of an unpacking room.
Evaluate the leaving time sufficiently because a situation of dew condensation occurring is
changed by the environmental temperature and humidity. (Recommended leaving time: 6 hours or
more with packing state)
③ Do not operate in high magnetic field. Circuit boards may be broken down by it.
④ This product is not designed as radiation hardened.
4.3.3 Other
① All GNDB and VDDB terminals should be used without any non-connected lines.
② Do not disassemble a product.
③ Pack the product with original shipping package, in order to avoid any damages during
transportation, when returning the product to NEC.
④ Put the spacer between inverter board and mounting surface, because of the protection for
contortion and the preservation of spacial distance.
