to qualified personnel.

WARNING

: To reduce the risk of fire or electric shock, do not expose this unit to rain or moisture.

The lightning flash with an arrowhead symbol within an equilateral triangle, is intended to alert the user to the

presence of uninsulated "dangerous voltage" within the productʼs 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 oper-

ating and maintenance (servicing) instructions in the literature accompanying the product.

Important Safety Instructions

any way, such as power supply cord or plug damage, or if liquid has been spilled or objects have fallen

into the unit, the unit has been exposed to rain or moisture, does not operate normally, or has been

dropped.
