CAUTION

Lead Free Soldered Boards

The circuit boards used in these models have been processed using
Lead Free Solder. The boards are identif ied by 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.

example 1

example 2

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 :

rebmuntraP retemaiD skrameR

91-500-046-7mm3.0gK52.0
02-500-046-7mm4.0gK05.0

52-500-046-7mm2.1gK00.1
62-500-046-7mm6.1gK00.1

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 recovery characteristics.

For more information on the use of Lead Free Solder, please refer to http://www.sony-training.com

UK PLUG WARNING

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

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