15. OVERLOADING
Do not overload wall outlets and extension cords as this can result in a risk of fire or electric shock.
16. OBJECT AND LIQUID ENTRY
Never push objects of any kind into this product through openings 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 on the product.
17. OUTDOOR ANTENNA GROUNDING
If an outside antenna is connected to the
product, be sure the antenna system is
grounded so as to provide some protection
against voltage surges and built-up static
charges. Section 810 of the National Electric
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 product, size of
grounding conductors, location of antenna
discharge product, connection to grounding
electrodes and requirements for grounding
electrodes.
18. SERVICING
Do not attempt to service this product yourself as
opening or removing covers may expose you to
dangerous voltage or other hazards. Refer all servicing to qualified service personnel.
19. REPLACEMENT PARTS
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.
