14. If an outside antenna is connected to the decoder equipment, be sure the antenna system is grounded so as to provide some
protection against voltage surges and built up static charges. In the U.S. Section 810 of the National Electrical Code, ANSII
NFPA 70 provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in
wire to an antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to grounding
electrodes, and requirements for the grounding electrode. See Figure.
15. For added protection for this HDTV Digital Receiver during a lightning storm, or when it is left unattended and unused for long
periods of time, unplug it from the wall outlet and disconnect the antenna. This will prevent damage to the decoder due to
lightning and power-line surges.
16. An outside antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits,
or where it can fall into such power lines or circuits. When installing an outside antenna system extreme care should betaken to
keep from touching such power lines or circuits as contact with them might be fatal.
17. Unplug this HDTV Digital Receiver from the wall outlet, and refer servicing to qualified service personnel under the following
conditions:
a. When the power cord or plug is damaged or frayed.
b. If liquid has been spilled into the HDTV Digital Receiver.
c. If the Digital Television Decoder has been exposed to rain or water.
d. If the HDTV Digital Receiver does not operate normally by following the operating instructions. Adjust only those controls
that are covered by the operating instructions as improper adjustment of other controls may result in damage and will
often require extensive work by a qualified technician to restore the HDTV Digital Receiver to normal operation.
e. If the HDTV Digital Receiver has been dropped or the cabinet has been damaged.
f. When the HDTV Digital Receiver exhibits a distinct change in performance - this indicates a need for service.
18. Do not attempt to service this Digital Television Decoder yourself as opening or removing covers may expose you to dangerous
voltage or other hazards. Refer all servicing to qualified service personnel.
19. When replacement parts are required, be sure the service technician has used replacement parts specified by the
manufacturer that have the same characteristics as the original part. Unauthorized substitutions may result in fire, electric
shock, or other hazards.
20. Upon completion of any service or repairs to this HDTV Digital Receiver, ask the service technician to perform routine safety
checks to determine that the decoder is in safe operating condition.
21. WARNING: TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.
22. CAUTION: TO PREVENT ELECTRIC SHOCK DO NOT USE THIS (POLARIZED) PLUG WITH A RECEPTACLE OR OTHER
OUTLET UNLESS THE BLADES CAN BE FULLY INSERTED TO PREVENT BLADE EXPOSURE.
