The circuit boards used in these models have been processed using 
Lead Free Solder. The boards are identified by the LF logo located 
close to the board designation e.g. H1 etc [ see example ]. The 
servicing of these boards requires special precautions to be taken as 
outlined below. 

Lead Free Solder material must be used to comply with environmental requirements of new solder joints. Lead Free Solder is available under
the  following part numbers :

Due to the higher melting point of Lead Free Solder the soldering iron tip temperature needs to be set to 370 degrees centigrade. This re-
quires soldering equipment capable of accurate temperature control coupled with a good heat recovery characteristics.

WARNING (UK Models only)

The flexible mains lead is supplied connected to a B.S. 1363 fused 
plug having a fuse of the correct rating for the set. Should the fuse 
need to be replaced, use a fuse of the same rating approved by ASTA 
to BS 1362, ie one that carries the 

 mark.

IF THE PLUG SUPPLIED WITH THIS APPLIANCE IS NOT SUITABLE 
FOR THE OUTLET SOCKETS IN YOUR HOME, IT SHOULD BE CUT 
OFF AND AN APPROPRIATE PLUG FITTED. THE PLUG SEVERED 
FROM THE MAINS LEAD MUST BE DESTROYED AS A PLUG WITH 

BARED WIRES IS DANGEROUS IF ENGAGED IN A LIVE SOCKET.

When an alternative type of plug is used, it should be fitted with the 
correct rating fuse, otherwise the circuit should be protected by the 
same rating fuse at the distribution board.
