by ASTA or BSI to BS1362
Check for the ASRA 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

4 HOW TO REPLACE THE LITHIUM BATTERY
(PROCEDURE)
1.Remove the Side Case (L) C.B.A.. (Refer to Disassembly Procedures.)
2.Unsolder the Lithium Battery “ML-621S/F9D” and then replace the new one. (See Fig. B1.)
3.Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type.
Fig. B1
Note:
The lithium battery is a critical component. (Type No.: N9ZZ00000286)
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.
