No license, express or implied, is granted under any patent, copyright or other intellectual property right of NEC. 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.

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. 2.4. FUSE Fuse Parameter Rating Fusing current Remarks Type Supplier 1.75A VDDB CCP2E35HTTE KOA Corporation 3.5A Note1 72V Note1: The power supply capacity should be more than the fusing current. If it is less than the fusing current, the fuse may not blow in a short time, and then nasty smell, smoke and so on may occur. DATA SHEET DOD-PP-0096 (3rd edition) 5 84PW041 2.5.

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. Resistor control BRTH BRTI R • Luminance ratio Note1 Resistance Luminance ratio 0Ω 20% (Min. Luminance) 10kΩ 100% (Max. Luminance) • 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. Voltage control • Luminance ratio Note1 BRTI signal (VBI) Luminance ratio 0V 20% (Min. Luminance) 2.5V 100% (Max. Luminance) Note1: These data are the target values. 3. RELIABILITY TEST This test is in accordance with the Reliability Test of the adaptable LCD module. Refer to Reliability Test of the adaptable LCD module. DATA SHEET DOD-PP-0096 (3rd edition) 7 84PW041 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 electric 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 (LCD module) 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. DATA SHEET DOD-PP-0096 (3rd edition) 8 84PW041 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. 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. 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 of 1.0mm thickness or more on a product rear side, because of the protection for contortion. Spacer example: Thickness= 1.0mm (min.) Diameter (φ) = 5.0mm (Recommendation) DATA SHEET DOD-PP-0096 (3rd edition) 9 84PW041 5.
