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 54ºF to

72ºF (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

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

(2/3)

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

8. Always ensure that all internal wirings are in accordance before re-assembling the

external casing after a repairing completed. Do not allow internal wiring to be

pinched by cabinets, panels, etc. Any error in reassembly or wiring can result in

electrical leakage, flame, etc., and may be hazardous.

9. NEVER remodel the product in any way. Remodeling can result in improper

operation, malfunction, or electrical leakage and flame, which may be hazardous.

10. Always perform an AC leakage current checking on the exposed metallic parts of the

cabinet such as antennas, terminals, screw heads, metal overlays, control shafts

and etc. to be sure that the set is safe to operate without any dangerous of electrical

shocks before returning the set to the customer.

11. The leakage current checking. (After completing the work, measure the leakage

current to prevent an electrical shock.)

 Plug the AC line cord directly into a 120V AC outlet. Do not use an isolation

transformer for this check.

 Use an AC voltmeter having 5000 ohms per volt or more sensitivity in the following

manner.

Connect a 1500 ohm 10 watt resistor, paralleled by a 0.15 µF, AC type capacitor, between

a known good earth ground (water pipe, conduit, etc.) and the exposed metallic parts, one

at a time. Measure the AC voltage across the combination of 1500 ohm resistor and 0.15

µF capacitor. Reverse the AC plug at the AC outlet and repeat AC voltage measurements

for each exposed metallic part. Voltage measured must not exceed 0.3 volts rms. This

corresponds to 0.2 milliamp. AC. Any value exceeding this limit constitutes a potential

shock hazard and must be corrected immediately.

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.
