CAUTION
SHORT CIRCUIT THE ANODE OF THE PICTURE TUBE
AND THE ANODE CAP TO THE METAL CHASSIS, CRT
SHIELD, OR CARBON PAINTED ON THE CRT, AFTER
REMOVING THE ANODE.
WARNING!!
AN ISOLATION TRANSFORMER SHOULD BE USED
DURING ANY SERVICE TO AVOID POSSIBLE SHOCK
HAZARD, BECAUSE OF LIVE CHASSIS. THE CHASSIS
OF THIS RECEIVER IS DIRECTLY CONNECTED TO THE
AC POWER LINE.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY SHADING AND MARK
ON THE SCHEMATIC DIAGRAMS, 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. CIRCUIT ADJUSTMENTS THAT
ARE CRITICAL FOR SAFE OPERATION ARE IDENTIFIED
IN THIS MANUAL. FOLLOW THESE PROCEDURES
WHENEVER CRITICAL COMPONENTS ARE REPLACED
OR IMPROPER OPERATION IS SUSPECTED.
ATTENTION!!
APRES AVOIR DECONNECTE LE CAP DE L'ANODE, 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 RESQUE D'ELECTROCUTION PROVENANT D'UN
CHÁSSIS SOUS TENSION, UN TRANSFORMATEUR D'ISOLEMENT DOIT
ETRE UTILISÉ LORS DE TOUT DÉPANNAGE. LE CHÁSSIS DE CE
RÉCEPTEUR EST DIRECTEMENT RACCORDÉ À L'ALIMENTATION
SECTEUR.
ATTENTION AUX COMPOSANTS RELATIFS A LA SECURITE!!
LES COMPOSANTS IDENTIFIES PAR UNE TRAME ET PAR UNE MARQUE
SUR LES SCHEMAS DE PRINCIPE, LES VUES EXPLOSEES ET LES
LISTES DE PIECES SONT D'UNEIMPORTANCE CRITIQUE POUR LA
SECURITE DU FONCTIONNEMENT. NE LES REMPLACER QUE PAR DES
COMPOSANTS SONY DONT LE NUMERO DE PIECE EST INDIQUE DANS
LE PRESENT MANUEL OU DANS DES SUPPLEMENTS PUBLIES PAR
SONY. LES REGLAGES DE CIRCUIT DONT L'IMPORTANCE EST CRI-
TIQUE POUR LA SECURITE DU FONCTIONNEMENT SONT IDENTIFIES
DANS LE PRESENT MANUEL. SUIVRE CES PROCEDURES LORS DE
CHAQUE REMPLACEMENT DE COMPOSANTS CRITIQUES, OU
LORSQU'UN MAUVAIS FONTIONNEMENT SUSPECTE.
