CAUTION
Damage requiring service
Unplug this converter box from the power outlet and refer servicing to qualified service personnel
under the following conditions:
l When the power supply cord or plug is damaged or frayed.
l If liquid has been spilled or objects have fallen into your converter box.
l If your converter box has been exposed to rain or water.
l If your converter box does not operate normally by following the operating instructions.
Adjust only those controls that are covered by the operating instructions because incorrect
adjustment of other controls may result in damage and will often require extensive work by
a qualified technician to restore your converter box to its normal operation.

l When your converter box exhibits a distinct change in performance.
Outdoor antenna grounding
If an outside antenna or cable system is connected to your converter box, make sure that the
antenna or cable system is grounded to provide some protection against voltage surges and
built-up static charges. Article 810 of the National Electrical Code, ANSI/NFPA No. 70, provides
information with respect to correct grounding of the mast and supporting structure, grounding of
the lead-in wire to an antenna discharge unit, size of grounding conductors, location of the
antenna-discharge unit, connection to grounding electrodes, and requirements for the
grounding electrode.
