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 30ºC to

40ºC (54ºF to 72ºF). 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.
