GREEN PRODUCT PROCUREMENT

The EC is actively promoting the WEEE & RoHS Directives that define standards for recycling

and reuse of Waste Electrical and Electronic Equipment and for the Restriction of the use of

certain Hazardous Substances. From July 1, 2006, the RoHS Directive will prohibit any

marketing of new products containing the restricted substances.

Increasing attention is given to issues related to the global environmental. Toshiba Corporation

recognizes environmental protection as a key management tasks, and is doing its utmost to

enhance and improve the quality and scope of its environmental activities. In line with this,

Toshiba proactively promotes Green Procurement, and seeks to purchase and use products,

parts and materials that have low environmental impacts.

Green procurement of parts is not only confined to manufacture. The same green parts used in

manufacture must also be used as replacement parts.

LEAD-FREE SOLDER

This product is manufactured using lead-free solder as a part of a movement within the

consumer products industry at large to be environmentally responsible. Lead-free solder must be

used in the servicing and repair of this product.

WARNING: This product is manufactured using lead free solder.

DO NOT USE LEAD BASED SOLDER TO REPAIR THIS PRODUCT!

The melting temperature of lead-free solder is higher than that of leaded solder by 86ºF to 104ºF

(30ºC to 40ºC). Use of a soldering iron designed for lead-based solders to repair product made

with lead-free solder may result in damage to the component and or PCB being soldered. Great

care should be made to ensure high-quality soldering when servicing this product especially

when soldering large components, through-hole pins, and on PCBs as the level of heat required

to melt lead-free solder is high.

SAFETY INSTRUCTION

Product Safety Notice

Many electrical and mechanical parts in this chassis have special safety-related characteristics.

These characteristics are often passed unnoticed by a visual inspection and the protection

afforded by them cannot necessarily be obtained by using replacement components rated for

higher voltage, wattage, etc. Replacement parts which have these special safety characteristics

are identified in this manual and its supplements; electrical components having such features are

identified by the international hazard symbols on the schematic diagram and the parts list.

Before replacing any of these components, read the parts list in this manual carefully. The use of

substitute replacement parts which do not have the same safety characteristics as specified in

the parts list may create electrical shock, fire, or other hazards.

SAFETY INSTRUCTION

Handling the LCD Module

Safety Precaution

In the event that the screen is damaged or the liquid crystal (fluid) leaks, do not breathe in or

drink this fluid.

Also, never touch this fluid. Such actions could cause toxicity or skin irritation. If this fluid should

enter the mouth, rinse the mouth thoroughly with water. If the fluid should contact the skin or

clothing, wipe off with alcohol, etc., and rinse thoroughly with water. If the fluid should enter the

eyes, immediately rinse the eyes thoroughly with running water.

Precautions for Handling the LCD Module

CAUTION: The metal edges of the LCD module are sharp, handle it with care.

The LCD module can easily be damaged during disassembly or reassembly; therefore, always

observe the following precautions when handling the module.

1. When attaching the LCD module to the LCD cover, position it appropriately and fasten at

the position where the display can be viewed most conveniently.

2. Carefully align the holes at all four corners of the LCD module with the corresponding holes

in the LCD cover and fasten with screws. Do not strongly push on the module because any

impact can adversely affect the performance. Also use caution when handling the polarized

screen because it can easily be damaged.

3. If the panel surface becomes soiled, wipe with cotton or a soft cloth. If this does not remove

the soiling, breathe on the surface and then wipe again.

If the panel surface is extremely solied, use a CRT cleaner as a cleaner. Wipe off the panel

surface by drop the cleaner on the cloth. Do not drop the cleaner on the panel. Pay

attention not to scratch the panel surface.

4. Leaving water or other fluids on the panel screen for an extended period of time can result

in discoloration or stripes. Immediately remove any type of fluid from the screen.

5. Glass is used in the panel, so do not drop or strike with hard objects. Such actions can

damage the panel.

6. CMOS-LSI circuitry is used in the LCD module, so avoid damage due to static electricity.

When handling the module, use a wrist ground or anchor ground.

7. Do not expose the LCD module to direct sunlight or strong ultraviolet rays for an extended

period of time.

8. Do not store the LCD module below the temperature conditions described in the

specifications. Failure to do so could result in freezing of the liquid crystal due to cold air or

loss of resilience or other damage.

9. Do not disassemble the LCD module. Such actions could result in improper operation.

10. When transporting the LCD module, do not use packing containing epoxy resin (amine) or

silicon resin (alcohol or oxim). The gas generated by these materials can cause loss of

polarity.
