b) If liquid has been spilled into, or objects have fallen into the product.
c) If the product has been exposed to rain or water.
d) If the product does not operate when used according to the operating instructions.
Adjust only those controls that are covered by the operating instructions as an improper adjustment of other
controls may interfere with the productÕs normal operation.
e) If the product has been dropped or damaged in any way.
f) When the product exhibits a distinct change in performance-this indicates a need for service.
16. Servicing-The user should not attempt to service the product beyond that described in the operating instruction. All
servicing should be referred to qualified service personnel.
17. Power Lines-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 be taken to keep from touching power lines or circuits as contact with them
might be fatal.
18. If an outside antenna is connected to the receiver, be sure the antenna system is grounded so as to provide some
protection against voltage surges and built up static. Section 810 of the National Electrical Code ANSI/NEFA 70
provides information with respect to proper grounding of the mast and supporting structure, grounding conductress,
location of antenna-discharge unit, size of grounding electrodes, and requirements for the grounding electrode (see
figure).
19. Cleaning-Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners.
Use a damp cloth for cleaning.
20. Lightning-For added protection for this product 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 or cable system. This will prevent
damage to the product due to lightning and power-line surges.
21. Safety Check-Upon completion of any service or repairs to this product, ask the service technician to perform safety
checks to determine that the product is in proper operation condition.
22. Overloading-Do not overload wall outlets, extension cords, or integral convenience receptacles as this can result in a
risk of fir or electric shock.
Invisible laser radiation will be emitted when the product is open and interlocks are defeated. Do not defeat the safety
interlocks.
