IMPORTANT SAFETY INSTRUCTIONS
14. Outdoor Antenna Grounding – 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 charges. Article 810 of
the National Electrical Code, ANSI/NFPA70, provides
information with regard 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. 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.
16. Power Lines – An outside antenna system should not be located in the vicinity of over head 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 such power lines or circuits as contact with
them might be fatal.
17. Overloading – Do not overload wall outlets, extension cords, or integral convenience receptacles as this can result
in a risk of fire or electric shock.

dangerous voltage points or short-out parts that could result in a fire or electric shock. Never spill liquid of any kind
on the product.

b) Liquid has been spilled, 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 normally by following the operating instructions. Adjust only those
controls that are covered by the operating instructions as an improper adjustment of other controls may
result in damage and will of then require extensive work by a qualified technician to restore the product
to its normal operation.
e) If the product has been dropped or damaged in anyway, and
f) When the product exhibits a distinct change in performance – this indicates a need for service.

3. Your remote control for either your TV or VCR/ DVD player may have source input selections as well
as detailed as the following: “Video, Video 1, Game, AUX, EXT or LINE-IN.” Choosing one of those
sources in most cases should display the lyrics from your CDG Machine as well.
