the power switch

- Do not place this monitor on an unstable base.

- Keep the monitor away from heat generating equipment and moist, dusty or unclean places.

- Slots in the cabinet are provided for ventilation.
Do not block the air flow through the slots.

1.2. Synchronization

The monitor synchronizes only to the timing signals
mentioned below. Do not use other display modes.

1.3. Image Properties

Normally the picture does not need any adjustment during introduction because the properties for
the most commonly used display modes are stores in a non-- volatile memory of the monitor.

However you might need Clock Phase and H.Size adjustments.

The display is optimised for 1280 x 1024 / 60 Hz reso­lution. Display modes with smaller resolution have
black border around the picture.

A steady picture may leave a shadow on the screen. It
is annoying but not dangerous -- the shadow disap­pears in time. You may avoid the shadow with power
management function.

The display consists of 3 932 160 individually con­trolled pixels. Some of them may be b lack or emit a
constant white or colored light. It is an intrinsic char­acteristic of LCD technology and is not a defect.

1.4. Cleaning

Screen

Do not use any abrasives or hard objects to remove a strain, it may damage surface of the
screen.

Do not use water or any other liquid for cleaning.

Use a soft, clean and dry cloth (e.g. Nokia Hitec 860003) for cleaning. The use of microfibre cloth is
recommended. Dampen the cloth with water or mild detergent if necessary.

If liquid is splashed on the screen, dry the screen immediately.

Cabinet

Use a cloth damped with a mild detergent solvent to clean the cabinet. Do not use strong solvents
(e.g. acetone) because they may damage the surface of the cabinet. Do not use aerosol cleaners.

5. Display Modes

- The s creen has 1280 horizontally addressable pixels and vertically 1024 pixels. If the incoming
signal res olution is 1280 x 1024, the picture fills whole screen.

- If the resolution of the signal is less than 1280 x 1024, the picture does not fill the whole
screen and as a result there may be a black border around the picture.

- The monitor however enlarges the picture by inserting pixels at regular intervals making the
black border as small as possible.

- Due to the insertion of the pixels, characters may look
different depending on the page they appear on the
screen (e.g. the letter “h”)

- NOTE: The aspect ration may not be correct at signal resolutions less than optimum.

7. Workshop Maintenance

7.1. Important Safety Notice

For your own safety, use always safety isolating transformer when repairing the monitor.

!

Do not touch an inverter --- on which is stuck a caution label --- while t he LCD module is under

the operation, bacause of dangerous high voltage.

!

Do not touch the screen with hard objects e.g. pencil nor with fingers. Dry the screen

immediately, if liquid is splashed on the screen.
The monitor display contains a small amount of liquid which may run out if the monitor display is

broken. If touched the liquid may injury skin and eyes. In case of touch, rinse the skin with water
and if you got liquid into eyes, get in contact with physician after rinsing the eye with water.

Since TFT-- LCD cell and bacllight element are made of fragile glass material, impulse and pressure
to the LCD module should be avoided.

When the module is operating, do not lose CLK, HS or Vsync signal. If any one of these signals is
lost, the LCD panel would be damaged.

7.2. ESD-- Sensitive Parts

AstheelectrostaticdischargesmaybreaktheLCDmodule,handletheLCDmodulewithcare
against electrostatic discharges.

To prevent damage, when working with electrostatic discharge (ESD) sensitive parts, observe the
following instructions:

- Keep the ESD-- sensitive part in its original shipping container until you are ready to install the
part into the component card.

- Just before touching the ESD-- sensitive part, discharge to the monitor any static electricity in
your body; do this by touching the metal frame or cover of the machine. If possible, keep one
hand on the frame when inserting or removing a logic card, for example.

-HoldtheESD-sensitive part by its edge; do not touch its pins.

7.3. Test Equipment

The following test equipment are required to adjustment procedure.

- Safety isolating transformer

- Digital multimeter: Fluke 87 or equivalent true RMS multimeter

- Signal generator: VTG220 + PC or programmable video generator

- Color analyzer: e.g. Topcom BM-- 7

- Oscilloscope 40-- 1 00 MHz band width

- ESD protection necessary

- Nokia Monitor Setup diskette

8. Precautions

Please pay attention to the following when the TFT-- LCD module with the Back-- light unit is used,
handled and mounted.

8.1. Precautions to Mounting

- Since the module is thin and heavy, applying strong force to a part of the module may cause
partial deformation of frame or mould, and cause malfunctions of the module.

- The module shall gently and firmly be held by both hands. Never hold the longer side of the
module by just one hand in order not to cause any internal malfunction. Never drop or hit the
module

- The module shall be installed with mounting holes at each corner of the module.

- Uneven force such as twisted stress shall not be applied to the module when the module is
mounted on the cover case. And the cover case must have sufficient strength so that external
force can not be transmitted directly to the module.

- Materials with acetic acid type or choline type shall not be used for the cover case as well as oth­er parts and boards near the module. Because, gases from the materials at higher temperature
are corrosive and attack the module. Acetic acid type attacks the polarizer. Choline type attacks
electric circuits due to electrochemical reaction.

- The polarizer on the TFT-- LCD cell shall carefully be handled due to its softness, and shall not be
touched, pushed or rubbed with glass, tweezers or anything harder than HB pencil lead. The
surface of the polarizer shall not be touched and rubbed with bare hands, greasy clothes or
dusty clothes with chemical treatment. (Some cosmetics are detrimental to the polarizer.)

- Saliva or water drops shall be immediately wiped off. Otherwise, the portion of the polarizer may
be deformed and its color may be faded.

- The module shall not be opened or modified. Otherwise, it may cause malfunctions.

- Metallic bezel of the module shall not be handled with bare hand or dirty gloves. Otherwise, col­or of the metallic frame may become dirty during its storage. It is recommended to use both
clean soft gloves and clean fingerstalls when the module is handled at incoming inspection pro­cess and production (assembly) process.

- The cable for lamp (CFL) shall not be pull or held.

8.2. Electrostatic Discharge Control

- SincethemoduleconsistsofTFT-- LCD cell and electronic circuits with CMOS-- ICs, which are
very weak to electrostatic discharge, persons who are handling the module shall be grounded
through adequate such as list band. Pins of I/F connector shall not be touched with bare hands.

- Protection film for polarizer on the module shall be slowly peeled off just before the use so that
the electrostatic charge can be minimized.

8.3. Precautions to Strong Light Exposure

- The module shall not be exposed under strong light. Otherwise, characteristic of the polarizer
and color filter in the module may be degraded.

8.4. Precautions to Storage

When the module for replacement are stored for long time, following precautions shall be taken care
off:

- The module shall be stored in a dark place. It is prohibited to apply sunlight or fluorescent light
during the storage. The module shall be stored at 5 to 35C at normal humidity (60% RH or less).

- The surface of the polarizer shall not come in contact with any other object. It is recommended
that the module shall be stored in the same shipping container that Nec used.

456A 19

8.5. Precautions to Handling Protection Film

- The protection film for polarizer shall be pealed off slowly and carefully by persons who are elec­trically grounded with adequate methods such as list bands. Besides, ionized air shall be blown
over during the peeling action. Dusts on the polarizer shall be blown off by an ionized nitrogen
gun and so on.

- The protection film shall be peeling off without rubbing it to the polarizer. Because, if the film is
rubbed together with polarizer, since the film is attached to the polarizer with a small amount of
adhesive, the adhesive may remain on the polarizer.

- The module with protection film shall be stored at the conditions explained in 7.4. However, if the
storing time is too long, the adhesive may remain on the polarizer even after the protection film is
slowly peeled off. If the module is stored at higher temperature and/or higher humidity, the adhe­sive may remain more on the polarizer. The remained adhesive may causes non-- uniformity.

- The remained adhesive or its vestige on the polarizer shall be wiped off with absorbent cotton or
other soft materials such as chamois

9. Replacing Lamp Holder Set (Backlight)

9.1. Precautions to Replacing Lamp Holder Set

- During the procedures, all power supplies not only to the module but also to the inverter shall be
switched off.

- Replacing work shall be started after the inverter and backlights become sufficiently cool.

- Special care shall be taken to the display area in order not to damage its surface

- The shall not be touched with bare hands to protect its surface from stains.

- It is recommended to use clean soft gloves and hold a cable holder of the backlight assembly
during the replacing work in order to protect not only the display area of the module and surface
of backlight but also a serviceman himself.

- Backlight assembly shall be pulled off slowly and straight without twisting or rotating. When it is
inserted, the same care shall be taken.
