CAUTION
Lead Free Soldered Boards
The circuit boards listed below [Table 1] used in these models
ma have been processed using Lead Free Solder. The boards are
identified b the LF logo located close to the board designation
e.g. F1, H1 etc [ see examples ]. The servicing of these boards
requires special precautions to be taken as outlined below.
Table 1
example 1
example 2
It is strongl recommended to use Lead Free Solder material in order to guarantee optimal qualit 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
requires soldering equipment capable of accurate temperature control coupled with a good heat recover characteristics.
For more information on the use of Lead Free Solder, please refer to http://www.sony-training.com

How to replace the fuse.
Open the fuse compartment with
a screwdriver blade and replace
the fuse.
FUSE
WARNING (UK Models only)
The flexible mains lead is supplied connected to a B.S. 1363 fused
plug having a fuse of 5 AMP rating. Should the fuse need to be
replaced, use a 5AMP FUSE approved b ASTA to BS 1362, ie one
that carries the ASA
T mark.
IF THE PLUG SUPPLIED WITH THIS APPLIANCE IS NOT SUIT-
ABLE 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 t pe of plug is used, it should be fitted with a
5 AMP FUSE, otherwise the circuit should be protected b a 5AMP
FUSE at the distribution board.
