15) Apparatus should not be exposed to dripping or splashing, and objects filled with liquids, such
as vases, should not be placed on the apparatus.
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 be taken to keep from touching such
power lines or circuits, as contact with them might be fatal.
17) Do not overload wall outlets and extension cords, as this can result in a risk of fire or electric
shock.
18) Do not push objects through any openings in this unit, as they may touch dangerous voltage
points or short out parts that could result in fire or electric shock. Never spill or spray any type of
liquid into the unit.
19) If an outside antenna or cable system is
connected to the unit, be sure the antenna or
cable system is grounded to provide some
protection against voltage surges and built-up
static charges, Section 810 of the National
Electrical Code, ANSI/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.
20) When replacement parts are required, be sure the service technician uses replacement parts
specified by the manufacturer or those that have the same characteristics as the original part.
Unauthorized substitutions may result in fire, electric shock or other hazards.
21) Upon completion of any service or repairs to this unit, ask the service technician to perform
safety checks to determine that the unit is in proper operating condition.
22) Keep your fingers clear of the disc slot as it is closing. It may cause injury.
