Note1: When designing of the power supply, take the measures for the prevention of surge voltage.
Note2: The power supply lines (VDDB and GNDB) occurs large ripple voltage while 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
source lines (VDDB and GNDB) to reduce the noise, if the noise occurred in the circuit.

Note1: The power supply capacity should be more than the fusing current. If the power capacity is less
than the fusing current, the fuse may not blow for a short time, and then nasty smell, smoking and
so on may occur.

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

• Adjustment
Voltage control method works, when BRTL terminal is 0V and BRTH voltage is input between
BRTL and BRTH terminal. This control method can carry out continuation adjustment of
luminance. Luminance is maximum when BRTH terminal is Open.
Less than 0.5V causes backlight off.

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
that customer will get an electric shock.
∗ Do not remove the inverter protection sheet, because there is a danger that
customer will get 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 touch the mounting parts when customer pulls out products from
packing box. If customer touches it, products may be broken down or out of adjustment, because of
stress to mounting parts.
② Take the measures of electrostatic discharge such as earth band, ionic shower and so on, when
customer deals with the product, because products may be damaged by electrostatic.
③ Do not push-pull the interface connectors while the product is working, because wrong power
sequence may break down the product.
④ Do not hook cables nor pull connection cables such as lamp cable and so on, for fear of 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.

4.3.2 Environment
① Do not operate or store in high temperature, high humidity, dewdrop atmosphere or corrosive gases.
Keep the product in antistatic pouch in room temperature, because of avoidance for dusts and sunlight,
if customer stores the product.
② In order to prevent dew condensation occurring by temperature difference, the product packing box
should be opened after leave under the environment of an unpacking room temperature enough.
Because a situation of dew condensation occurring is changed by the environmental temperature and
humidity, evaluate the leaving time sufficiently. (Recommendation leaving time: 6 hour or more with
packing state)
③ Do not operate in high magnetic field. Product 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 without permission of NEC.
③ Pack the product with original shipping package, because of avoidance of some damages during
transportation, when customer returns it to NEC.
④ Put the spacer of 1.0mm thickness or more on a product rear side, because of the protection for
contortion.
e.g., Washer condition: The washer thickness = 1.0mm (min.)
The washer diameter (φ) = 5.0mm (Recommendation)
