(*1) 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.
(*2) 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 86°F to 104°F
(30°C to 40°C). 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.

5. TAKE CARE TO DEAL WITH THE
CATHODE-RAY TUBE
In the condition that an explosion-proof cathode-
ray tube is set in this equipment, safety is
secured against implosion. However, when
removing it or serving from backward, it is
dangerous to give a shock. Take enough care to
deal with it.
HOW TO ORDER PARTS
Please include the following informations when you order parts. (Particularly the VERSION LETTER.)
1. MODEL NUMBER and VERSION LETTER
The MODEL NUMBER can be found on the back of each product and the VERSION LETTER can be
found at the end of the SERIAL NUMBER.
2. PART NO. and DESCRIPTION
You can find it in your SERVICE MANUAL.
IMPORTANT
When you exchange IC and Transistor with a heat sink, apply silicon grease on the contact section of
the heat sink. Befor applying new silicon grease, remove all the old silicon grease.
(Old grease may cause damages to the IC and Transistor.)

the ADDRESS until required ADDRESS to be changed is reached.
5. Press VOL. UP/DOWN button to select DATA. When DATA is selected, it will "blink".
6. Again, step through the DATA using UP/DOWN button until required DATA value has been selected.
7. Pressing LEFT/RIGHT button will take you back to ADDRESS for further selection if necessary.
8. Repeat steps 4 to 6 until all data has been checked.
9. When satisfied correct DATA has been entered, turn POWER off (return to STANDBY MODE) to finish DATA input.
After the data input, set to the initializing of shipping.
10. Turn POWER on.
11. Press both VOL. DOWN button on the set and Channel button (1) on the remote control for more than 2 seconds.
12. After the finishing of the initializing of shipping, the unit will turn off automatically.
The unit will now have the correct DATA for the new MEMORY IC.
