referred to qualified service personnel.
17. Outdoor antenna grounding
– If an outside
antenna is connected to the appliance, 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/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,
c o n n e c t i o n t o g r o u n d i n g e l e c t r o d e s , a n d
requirements for the grounding electrode. See
Figure.
18. 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 such power lines or circuits as contact
with them might be fatal.
19. AC outlets
– Do not connect other audio equipment
with a power consumption larger than that
specified to the AC outlet on the rear panel. Never
connect other electrical appliances, such as an
iron or toaster, to it to prevent fire or electric
shock.
20. Overloading
– Do not overload wall outlets, extension
cords, or integral convenience receptacles as this can
result in a risk of fire or electric shock.
21. Attachment

recommended by the appliance manufacturer as they
may cause hazards.
22. Replacement parts
– When replacement parts are
required, be sure the service technician has used
replacement parts specified by the manufacturer or
have the same characteristics as the original parts.
Unauthorized substitutions may result in fire, electric
shock, or other hazards.
23. Safety check
– Upon completion of any service or
repairs to this appliance, ask the service technician to
perform safety checks to determine that the appliance is
in proper operationg condition.
