1. Be sure to discharge the capacitor on FLASH P.C.B..
2. Be careful of the high voltage circuit on FLASH P.C.B. when servicing.

Before disassembling, perform "6.4. Forced full flash emission" for discharging capacitor.
The capacitor also can be discharged according to the following procedures.

1. Refer to the disassemble procedure and Remove the necessary parts/unit.
2. Put the insulation tube onto the lead part of Resistor (ERG5SJ102:1k

Ω /5W).

(an equivalent type of resistor may be used.)

3. Put the resistor between both terminals of capacitor on FLASH P.C.B. for approx. 5 seconds.
4. After discharging confirm that the capacitor voltage is lower than 10V using a voltmeter.

Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Elec-
trostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and
semiconductor "chip" components. The following techniques should be used to help reduce the incidence of component damage
caused by electrostatic 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 alumi-

num 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 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 compara-
ble conductive 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) suf-
ficient to damage an ES device).

Your attention is drawn to the fact that recording of pre-
recorded tapes or discs or other published or broadcast
material may infringe copyright laws.

To reduce the risk of fire or shock hazard, do not expose
this equipment to rain or moisture.

To reduce the risk of fire or shock hazard and annoying
interference, use the recommended accessories only.

 DO NOT REMOVE THE OUTER COVER
To prevent electric shock, do not remove the cover. No user
serviceable parts inside. Refer servicing to qualified service
personnel.

For your safety, please read the following text carefully.

This appliance is supplied with a moulded three-pin mains plug
for your safety and convenience.
A 5-ampere fuse is fitted in this plug.
Should the fuse need to be replaced please ensure that the
replacement fuse has a rating of 5 amperes and it is approved
by ASTA or BSI to BS1362
Check for the ASTA mark or the BSI mark on the body of the
fuse.

If the plug contains a removable fuse cover you must ensure
that it is refitted when the fuse is replaced.
If you lose the fuse cover, the plug must not be used until a
replacement cover is obtained.
A replacement fuse cover can be purchased from your local
Panasonic Dealer.

If the fitted moulded plug is unsuitable for the socket outlet in
your home then the fuse should be removed and the plug cut
off and disposed of safety.
There is a danger of severe electrical shock if the cut off plug is
inserted into any 13-ampere socket.

If a new plug is to be fitted please observe the wiring code as
shown below.
If in any doubt, please consult a qualified electrician.

The wires in this mains lead are coloured in accordance with
the following code:

As the colours of the wires in the mains lead of this appliance
may not correspond with the coloured markings identifying the
terminals in your plug, proceed as follows:

The wire which is coloured BLUE must be connected to the ter-
minal in the plug which is marked with the letter N or coloured
BLACK.

The wire which is coloured BROWN must be connected to the
terminal in the plug which is marked with the letter L or coloured
RED.

Under no circumstances should either of these wires be con-
nected to the earth terminal of the three pin plug, marked with
the letter E or the Earth Symbol.

Remove the Connector Cover as follows.

1. Remove the Fuse Cover with a screwdriver.

2. Replace the fuse and attach the Fuse cover.

1. Remove the SD OP P.C.B.. (Refer to Disassembly Procedures.)
2. Remove the Lithium battery (Ref. No. “B3901” at component side of SD OP P.C.B.) and then replace it into new one.

This Lithium battery is a critical component. 
(Type No.: ML-614 Manufactured by Energy Company, Panasonic Corporation)
It must never be subjected to excessive heat or discharge.
It must therefore only be fitted in requirement designed specifically for its use.
Replacement batteries must be of 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.

Above caution is applicable for a battery pack which is for HC-900M / 900 / X909 series, as well.
