Important Safety Instructions
1) Read these instructions.
2) Keep these instructions.
3) Heed all warnings.
4) Follow all instructions.
5) Do not use this apparatus near water.
6) Clean only with a dry cloth.
7) Do not block any ventilation openings. Install in
accordance with the manufacturer’s instructions.
8) Do not install near any heat sources such as ra-
diators, heat registers, stoves, or other apparatus
that produce heat.
9) Do not defeat the safety purpose of the polarized

placement of the obsolete outlet.
10) Protect the power cord from being walked on or
pinched, particularly at plugs, convenience re-
ceptacles, and the point where they exit from the
apparatus.
11) Only use attachments/accessories specified by
the manufacturer.
12) Use only with a cart, stand, bracket, or table
specified by the manufacturer, or sold with the ap-
paratus. When a cart is used, use caution when
moving the cart/apparatus combination to avoid
injury from tip-over.
13) Unplug this apparatus during lightning storms or
when unused for long periods of time.
14) Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has
been damaged in any way, such as power-supply
cord or plug is damaged, liquid has been spilled
or objects have fallen into the apparatus, the ap-
paratus has been exposed to rain or moisture,
does not operate normally, or has been dropped.
15) To reduce the risk of fire or electric shock, do not
expose this apparatus to rain or moisture.
