1. Read and follow all instructions carefully.

2. Do not operate this apparatus near water.

3. Clean only with a damp cloth.

4. Install only in accordance with the instructions in this manual.

7. Do not defeat the safety purpose of the polarized or grounding type plug. A polarized

blades and a third grounding prong. The wide blade or the third prong is provided for
your safety. If the provided plug does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.

8. Protect the power cord from being walked on or pinched, particularly at plugs,
convenience receptacles, and the point where it is attached to the apparatus.

9. Unplug this apparatus during lightning storms or when unused for long periods of
time. For complete protection against lightning strikes and related hazards, a more
sophisticated protection device is needed, such as the Furman PRO Series Power
Conditioners, or the AR-Series AC Line Voltage Regulators.

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
apparatus has been exposed to rain or moisture, does not operate normally, or
has been dropped.
