ELECTROSTATICALLY SENSATIVE DEVICES
Many solid-state devices (especially Integrated Circuits) are Electrostatically
Sensitive, and, therefore, require special handling techniques as described under
“Servicing Electrostatically Sensitive Devices,” on page two in this service literature.
FOR CONTINUED PROTECTION AGAINST
A RISK OF FIRE, REPLACE ONLY WITH
THE SAME TYPE 4A, 250V FUSE.
ATTENTION: POUR MAINTENIR LA PROTECTION
CONTRE LES RISQUES D' INCENDIE UTILISER UN
FUSIBLE DE RECHANGE DE MEME TYPE 4A, 250V.
CAUTION
4A 250V
