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 

WARNING:

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. 

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 

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, product components, etc. away from children as these items may cause injury. 

5. 

Depending on the model, use an isolation transformer or wear suitable gloves when servicing with the power on.  
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
