Important Safety Instructions

Consignes de sécurité à lire attentivement

The lightning flash with arrowhead symbol, within an equilateral triangle, 

is intended to alert the user to the presence of uninsulated "dangerous 

voltage" within the product's enclosure that may be of sufficient magnitude 

to constitute a risk of electric shock to persons. The exclamation point 

within an equilateral triangle is intended to alert the user to the presence 

of important operating and maintenance instructions in the literature ac

-

companying the device.

Le symbole de la flèche dans un triangle équilateral symbolisant la foudre 

est prévu pour sensibiliser l’utilisateur à la présence de tension de voltage 

non isolée à l’intérieur de l’appareil. Elle pourrait constituer un danger de 

risque de décharge électrique pour les utilisateurs. Le point d’exclamation 

dans le triangle équilatérale alerte l’utilisateur de la présence de consignes 

qu’il doit d’abord consulter avant d’utiliser l’appareil.
