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.

Le symbole éclair avec point de flèche à l’intérieur d’un triangle équilatéral 

est utilisé pour alerter l’utilisateur de la presence à l’intérieur du coffret de

“voltage dangereux” non isolé d’ampleur suffisante pour constituer un risque

d’éléctrocution.

The exclamation point within an equilateral triangle is intended to alert the

user to the presence of important operating and maintenance (servicing)

instructions in the literature accompanying the product.

Le point d’exclamation à l’intérieur d’un triangle équilatéral est employé pour

8. Do not defeat the safety purpose of 

the polarized or grounding-type plug. A

polarized plug has two blades with one

wider than the other. A grounding-type

plug has two blades and a third ground-

ing prong. The wide blade or the third

prong are provided for your safety. If the

apparatus has been damaged in any way,

such as power-supply  plug is damaged,

liquid has been spilled or objects have 

fallen into the apparatus, the apparatus has

been exposed to rain or moisture, does not

operate normally, or has been dropped.
13. To completely disconnect this equip-

ment from the mains, disconnect the power

supply cord plug from the receptacle.
14. Connect the subwoofer to a power 

supply of the type described in these

operation instructions or as marked on

the subwoofer.

This apparatus does not exceed the 

Class A/Class B (whichever is applicable)
