WARNING

This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of  California to

cause cancer, birth defects or other reproductive harm.

                                                                                                            Health & Safety Cod e Section 25249.6  – Proposition 65

NOTICE

(FOR CANADIAN MODEL ONLY)

Fuse symbols                 (fast operating fuse)   and/or                  (slow operating fuse) on PCB indicate that replacement

parts must be of identical designation.

REMARQUE

(POUR MODÈLE CANADIEN SEULEMENT)

Les  symboles  de fusible                (fusible de type rapide)   et/ou                  (fusible de type lent) sur CCI indiquent que

les pièces de remplacement doivent avoir la même désignation.

ANY MEASUREMENTS NOT WITHIN THE
LIMITS OUTLINED ABOVE ARE INDICATIVE
OF A POTENTIAL SHOCK HAZARD AND
MUST BE CORRECTED BEFORE RETURN-
