1. Safety Precautions
GENERAL GUIDELINES
1. IMPORTANT SAFETY NOTICE
There are special components used in this equipment which are
important for safety. These parts are marked by in the Schematic
Diagrams, Circuit Board Layout, Exploded Views and Replacement
Parts List. It is essentialthat these critical parts should be replaced with
1

manufacturer’s specified parts to prevent shock, fire, or other hazards.
Do not modify the original design without permission of manufacturer.
2. An Isolation Transformer should always be used during the servicing
of AC Adaptor whose chassis is not isolated from the AC power line.
Use a transformer of adequate power rating as this protects the
technician from accidents resulting in personalinjury from electrical
shocks. It will also protect AC Adaptor from being damaged by
accidental shorting that may occur during servicing.
3. When servicing, observe the original lead dress. If a short circuit is
found, replace all parts which have been overheated or damaged by the
short circuit.
4. After servicing, see to it that all the protective devices such as
insulation barriers, insulation papers shields are properly installed.
5. After servicing, make the following leakage current checks to prevent
the customer from being exposed to shock hazards.
LEAKAGE CURRENT COLD CHECK
1. Unplug the AC cord and connect a jumper between the two prongs on
the plug.
2. Measure the resistance value, with an ohmmeter, between the
jumpered AC plug and each exposed metallic cabinet part on the
equipment such as screwheads, connectors, control shafts, etc. When
the exposed metallic part has a return path to thechassis, the reading
should be between 1 M and 5.2 M . When the exposed metal does
not have a return path to the chassis, the reading must be infinity.
LEAKAGE CURRENT HOT CHECK
(See Figure 1.)
1. Plug the AC cord directly into the AC outlet. Do not use an isolation
transformer for this check.
2. Connect a 1.5 k , 10 W resistor, in parallel with a 0.15 F capacitor,
between each exposed metallic part on the set and a good earth
ground, as shown in Figure 1.
3. Use an AC voltmeter, with 1 k /V or more sensitivity, to measure the
potential across the resistor.
4. Check each exposed metallic part, and measure the voltage at each
point.
5. Reverse the AC plug in the AC outlet and repeat each of the above
2

measurements.
6. The potential at any point should not exceed 0.75 V RMS. A leakage
current tester (Simpson Model 229 or equivalent) may be used to make
the hot checks, leakage current must not exceed 1/2 mA. In case a
measurement is outside of thelimits specified, there is a possibility of a
shock hazard, and the equipment should be repaired and rechecked
before it is returned to the customer.

2. Prevention of Electro Static Discharge (ESD) to
Electrostatically Sensitive (ES) Device
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such
components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES
devices are integrated circuits and some field-effect transistorsand semiconductor "chip" components.
The following techniques should be used to help reduce the incidence of component damage caused
by electro static discharge (ESD).
1. Immediately before handling any semiconductor component or
semiconductor-equipped assembly, drain off any ESD on your body by
touching a known earth ground. Alternatively, obtain and wear a
commercially available discharging ESD wrist strap,which should be
removed for potential shock reasons prior to applying power to the unit
under test.
2. After removing an electrical assembly equipped with ES devices, place
the assembly on a conductive surface such as aluminum foil, to
prevent electrostatic charge buildup or exposure of the assembly.
3. Use only a grounded-tip soldering iron to solder or unsolder ES
devices.
4. Use only an antistatic solder removal device. Some solder removal
devices not classified as "antistatic (ESD protected)" can generate
electrical charge sufficient to damage ES devices.
5. Do not use freon-propelled chemicals. These can generate electrical
3

charges sufficient to damage ES devices.
6. Do not remove a replacement ES device from its protective package
until immediately before you are ready to install it. (Most replacement
ES devices are packaged with leads electrically shorted together by
conductive foam, aluminum foil or comparableconductive material).
7. Immediately before removing the protective material from the leads of a
replacement ES device, touch the protective material to the chassis or
circuit assembly into which the device will be installed.
CAUTION :
Be sure no power is applied to the chassis or circuit, and observe all
other safety precautions.
8. Minimize bodily motions when handling unpackaged replacement ES
devices. (Otherwise harmless motion such as the brushing together of
your clothes fabric or the lifting of your foot from a carpeted floor can
generate static electricity (ESD)sufficient to damage an ES device).

4. How to Replace the Lithium Battery
Remove the AEL C.B.A. (Refer to “ 8. Disassembly and Reassembly.”)
Unsolder the Lithium Battery “FS11091” and then replace the new one.

NOTE:
This Lithium battery is a critical component. (Type No.: FS11091
Manufactured by Panasonic.)
It must never be subjected to excessive heat or discharge.
It must therefore only be fitted in equipment designed specifically for its
use.
Replacement batteries must be of the same type and manufacture.
They must be fitted in the same manner and location as the original
battery, with the correct polarity contacts observed.
Do not attempt to re-charge the old battery or re-use it for any other
purpose.
It should be disposed of in waste products destined for burial rather than
incineration.
