WARNING (KV-32WS2U only)
The flexible mai ns lead is supplied connected to a B.S. 1363 fused plug
having a fuse of 5 AMP capacity. Should the fuse need to be replaced,
use a 5 AMP FUSE approved by ASTA to BS 1362, ie one that carr ie s the
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 ENGAGE D IN A LIVE OUTLET
SOCKET.
When an alte rnative type of plug is used it should be fitted with a 5 AMP
FUSE, otherwise the circuit shoul d be protected by a 5 AMP FUSE at the

WARNING !!
AN ISOLATING 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.
SAFETY-RELATED COMPONENT WARNING !!
COMPONENTS IDENTIFIED BY SHADING AND MARKED ON
THE SCHEMATIC DIAGRAMS, EXPLODED VIEWS AND IN THE
PARTS LIST ARE CRITICAL FOR SAFE OPERATION. REPLACE
THESE COMPONENTS WITH SONY PARTS WHOSE P ART NUMBERS
APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS
PUBLISHED BY SONY.
ATTENTION
APRES AVOIR DECONNECTE LE CAP DE’LANODE,
COURT-CIRCUITER L’ANODE DU TUBE CATHODIQUE ET
CELUI DE L’ANODE DU CAP AU CHASSIS METALLIQUE
DE L’APPAREIL, OU AU COUCHE DE CARBONE PEINTE
SUR LE TUBE CATHODIQUE OU AU BLINDAGE DU TUBE
CATHODIQUE.
ATTENTION !!
AFIN D’EVITER TOUT RISQUE D’ELECTROCUTION PROVENANT
D’UN CHÁSSIS SOUS TENTION, UN TRANSFORMATEUR
D’ISOLEMENT DOIT ETRE UTILISÈ LORS DE TOUT DÈPANNAGE.
LE CHÁSSIS DE CE RÈCEPTEUR EST DIRECTMENT RACCORDÈ
Á L’ALIMENTATION SECTEUR.
ATTENTION AUX COMPOSANTS RELATIFS Á LA
SÈCURITÈ !!
LES COMPOSANTS IDENTIFIÈS PAR UNE TRAME ET PAR UNE
MARQUE SUR LES SCHÈMAS DE PRINCIPE, LES VUES
EXPLOSÈES ET LES LISTES DE PIECES SONT D’UNE IMPORTANCE
CRITIQUE POUR LA SÈCURITÈ DU FONCTIONNEMENT, NE LES
REMPLACER QUE PAR DES COMPSANTS SONY DONT LE NUMÈRO
DE PIÈCE EST INDIQUÈ DANS LE PRÈSENT MANUEL OU DANS
