Lead Free Soldered Boards
The circuit boards listed below (Table 1) may have been processed using Lead Free Solder. The boards are
identified by the LF logo . e.g A,C board (see example).
The servicing of these boards requires special precautions to be taken as outlined below:
1. It is strongly recommended to use Sony Approved Lead Free Solder material in order to guarantee optimal
quality of new solder joints.
2. Due to higher melting point of Lead Free Solder, the soldering iron tip temperature needs to be set to chip
(350 degree centigrade) and lead component (380 degree centigrade) for not more than 4 seconds. This requires
soldering equipment capable of accurate temperature control coupled with a good heat recovery characteristics.
The flexible mains lead is supplied to connected a B.S. 1363 fused plug having a fuse of 5 AMP rating. Should the
fuse need to be replaced, use a 5 AMP FUSE approved by ASTA to BS 1362, i.e one that carries the
mark.

ASA
IF THE PLUG SUPPLIED WITH THIS APPLIANCE IS NOT SUITABLE FOR THE OUTLET SOCKETS IN YOUR
HOME, IT SHOULD BE CUT OFF AND 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 a 5 AMP FUSE, otherwise the circuit should be
protected by a 5 AMP FUSE at the distribution board.
