particularly at plugs, convenience receptacles, and the point
where they exit from the apparatus.
Refer all servicing to qualified service personnel. Servicing is

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.
