CAUTION:The relay contains devices sensitive to

electrostatic discharge (ESD). When working on the

relay with front or top cover removed, work surfaces

and personnel must be properly grounded or

equipment damage may result.

ATTENTION!:Le relais contient des pièces

sensibles aux décharges électrostatiques(DES). Quand

on travaille sur le relais avec le panneau avant ou du

dessus enlevé, les surfaces de travail et le personnel

doivent être mis à la terre convenablement pour éviter

les dommages à l'équipement.

CAUTION: There is danger of explosion if the

battery is incorrectly replaced. Replace only with

Ray-O-Vac®no. BR2335 or equivalent recommended

by manufacturer. Dispose of used batteries according

to the manufacturer’s instructions.

ATTENTION!: Il y a un danger d’explosion si la pile

électrique n’est pas correctement remplacée. Utiliser

exclusivement Ray-O-Vac®No. BR2335 ou un

équivalent recommandé par le fabricant. Se

débarrasser des piles usagées suivant les instructions

du fabricant.
