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 3 amp fuse is fitted in this plug.

Should the fuse need to be replaced please ensure that the replacement fuse has a rating of 3

amps and that it is approved by ASTA or BSI to BS 1362.

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 SAFELY.

THERE IS A DANGER OF SEVERE ELECTRICAL SHOCK IF THE CUT OFF PLUG IS INSERTED

INTO ANY 13 AMP SOCKET.

As the colours of the wires in the mains lead of this apparatus 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 terminal which is marked with

the letter N or coloured BLACK.

The wire which is coloured Brown must be connected to the terminal which is marked

with the letter L or coloured RED.

Under no circumstances should either of these wires be connected to the earth terminal of the

three pin plug, marked with the letter E or the Earth Symbol .

The mains plug on this equipment must be used to disconnect the mains power.
