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.

SAFETY INSTRUCTION

WARNING: BEFORE SERVICING THIS CHASSIS, READ THE "SAFETY PRECAUTION"

AND "PRODUCT SAFETY NOTICE" INSTRUCTIONS BELOW.

Safety Precaution

WARNING: SERVICING SHOULD NOT BE ATTEMPTED BY ANYONE UNFAMILIAR WITH

THE NECESSARY PRECAUTIONS ON THIS RECEIVER. THE FOLLOWING ARE THE

NECESSARY PRECAUTIONS TO BE OBSERVED BEFORE SERVICING THIS CHASSIS.

1. An isolation transformer should be connected in the power line between the receiver

and the AC line before any service is performed on the receiver.

2. Always disconnect the power plug before any disassembling of the product. It may

result in electrical shock.

3. When replacing a chassis in the cabinet, always be certain that all the protective

devices are put back in place, such as nonmetallic control knobs, insulating covers,

shields, isolation resistor-capacitor network, etc.

4. Always keep tools, components of the product, etc away from the children, These items

may cause injury to children.

5. Depending on the model, use an isolation transformer or wear suitable gloves when

servicing with the power on, and disconnect the power plug to avoid electrical shock

when replacing parts. In some cases, alternating current is also impressed in the

chassis, so electrical shock is possible if the chassis is contacted with the power on.

6. Always use the replacement parts specified for the particular model when making

repairs. The parts used in products require special safety characteristics such as

inflammability, voltage resistance, etc. therefore, use only replacement parts that have

these same characteristics. Use only the specified parts when the mark is indicated

in the circuit diagram or parts list.

7. Parts mounting and routing dressing of wirings should be the same as that used

originally. For safety purposes, insulating materials such as isolation tube or tape are

sometimes used and printed circuit boards are sometimes mounted floating. Also make

sure that wirings is routed and clamped to avoid parts that generate heat and which use

high voltage. Always follow the manufactured wiring routes / dressings.
