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.

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.
20. SAFETY CHECK
Upon completion of any service or repairs to this
