SAFETY-RELATED COMPONENT WARNING !!

COMPONENTS IDENTIFIED BY SHADING AND MARKED

  

 

  ON

THE EXPLODED VIEWS AND IN THE PARTS LIST ARE CRITICAL
FOR SAFE OPERATION. REPLACE THESE COMPONENTS WITH
SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN
THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.

WARNING !!

AN ISOLATION TRANSFORMER SHOULD BE USED DURING ANY
SERVICE WORK TO AVOID POSSIBLE SHOCK HAZARD DUE TO
LIVE CHASSIS, THE CHASSIS OF THIS RECEIVER IS DIRECTLY
CONNECTED TO THE POWER LINE.

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. F1, H1 etc [ see examples ]. 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 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

How to replace the fuse.
Open the fuse compartment with
a screwdriver blade and replace
the fuse.

FUSE

 

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 

ASA

T

 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.
