IMPORTANT NOTICE
WARNING:
You are requested that you shall not modify or alter the information or data provided
herein without prior written consent by Toshiba. Toshiba shall not be liable to
anybody for any damages, losses, expenses or costs, if any, incurred in connection
with or as a result of such modification or alteration.
THE INFORMATION OR DATA HEREIN SHALL BE PROVIDED "AS IS" WITHOUT ANY
WARRANTY OF ANY KIND, EITHER EXPRESS OR IMPLIED WARRANTY OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
Toshiba shall not be liable for any damages, losses, expenses or costs, if any,
incurred in connection with or as a result of use of any information or data provided
herein.

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.

(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.
Annex D
(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).

(3/4)
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.
b) 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.

(4/4)
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.
