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.
