6.3.2 Environment
6.3.3 Characteristics
6.3.4 Other
The following items are neither defects nor failures.
All GND, backlight inverter ground (GNDB), VCC and backlight inverter power supply voltage
(VDDB) terminals should be used without a non-connected line.
Do not disassemble a product or adjust volume without permission of NEC.
See "REPLACEMENT MANUAL FOR LAMP HOLDER SET", if customer would like to replace
backlight lamps.
Pay attention not to insert waste materials inside of products, if customer uses screwnails.
Pack the product with original shipping package, because of avoidance of some damages during
transportation, when customer returns it to NEC for repair and so on.
Do not press or rub on the sensitive display surface. If customer clean on the panel surface, NEC
recommends using the cloth with ethanolic liquid such as screen cleaner for LCD.
Do not push-pull the interface connectors while the product is working, because wrong power
sequence may break down the product.
Do not bend or unbend the lamp cable at the near part of the lamp holding rubber, to avoid the
damage for high voltage side of the lamp. This damage may cause a lamp breaking and abnormal
operation of high voltage circuit.
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.
In order to prevent dew condensation occurring by temperature difference, the product packing box
must 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)
Response time, luminance and color may be changed by ambient temperature.
The LCD may be seemed luminance non-uniformity, flicker, vertical seam or small spot by display
patterns.
Optical characteristics (e.g. luminance, display uniformity, etc.) gradually is going to change
depending on operating time, and especially low temperature, because the LCD has cold cathode
fluorescent lamps.
Do not display the fixed pattern for a long time because it may cause image sticking. Use a screen
saver, if the fixed pattern is displayed on the screen.
The display color may be changed by viewing angle because of the use of condenser sheet in the
backlight.
Optical characteristics may be changed by input signal timings.
The interference noise of input signal frequency for this product's signal processing board and
luminance control frequency of customer's backlight inverter may appear on a display. Set up
luminance control frequency of backlight inverter so that the interference noise does not appear.
Do not operate in high magnetic field. Circuit boards may be broken down by it.
This product is not designed as radiation hardened.
Use an original protection sheet on the product surface (polarizer). Adhesive type protection sheet
should be avoided, because it may change color or properties of the polarizer.
