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

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.

mark is indicated

(2/4)

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. Touch current check. (After completing the work, measure touch current to prevent an

electric shock.)

 Plug the AC cord directly into the AC outlet. Do NOT use an isolation transformer for

this check.

 Connect a measuring network for touch currents between each exposed metallic part

on the set and a good earth ground such as a water pipe.

(normative)

Measuring network for TOUCH CURRENTS

Resistance values in orms (Ω).

V: Voltmeter or oscilloscope

(r.m.s. or peak reading)

Input resistance :

1 MΩ Input capacitance : 200 pF Frequency range : 15 Hz to 1 MHz and d.c. respectively

Note: Appropriate measures should be taken to obtain the correct value in case of non

sinusoidal waveforms.

The measuring instrument is calibrated by comparing the frequency factor of with the solid line in figure F.2 of IEC 60990 at various frequencies. A calibration curve is constructed showing the deviation of

from the ideal curve as a function of

frequency.

TOUCH CURRENT =

/ 500 (peak value).

 The potential at any point (TOUCH CURRENT) expressed as voltage and does

not exceed the following value:

The part or contact of a TERMINAL is not HAZARDOUS LIVE if: a) The open-circuit voltage should not exceed 35 V (peak) a.c. or 60 V d.c. or, if a) is

not met.

The measurement of the TOUCH CURRENT shall be carried out in accordance

with IEC 60990, with the measuring network described in Annex D of this

standard.

The TOUCH CURRENT expressed as voltages and , does not exceed the following values:

- for a.c. : = 35 V (peak) and = 0.35 V (peak);

- for d.c. : = 1.0 V

Note: The limit values of = 0.35 V (peak) for a.c. and = 1.0 V for d.c.

correspond to the values 0.7 mA (peak) a.c. and 2.0 mA d.c.

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.
