13. Lightning - For added protection for this appliance 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 appliance due to lightning
and power-line surges.
14. Abnormal smell - If an abnormal smell or smoke is detected, imme-
diately turn the power OFF and unplug the appliance from the wall
outlet. Contact your dealer or nearest service center.
15. Damage requiring service - The appliance should be serviced by
qualified service personnel when:
A. The power-supply cord or the plug has been damaged.
B. Objects have fallen, or liquid has been spilled into the appliance.
C. The appliance has been exposed to rain or water.
D. The appliance does not appear to operate normally by following the
instruction manual. Adjust only those controls that are covered by the
instruction manual as an improper adjustment of other controls may
result in damage and will often require extensive work by a qualified
technician to restore the appliance to its normal operation.
E. The appliance has been dropped, or the enclosure damaged.
F. The appliance exhibits a marked change in performance.
16. Servicing - The user should not attempt to service the appliance be-
yond that described in the instruction manual. All other servicing should
be 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,
connection to grounding electrodes, and 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. Overloading - Do not overload wall outlets, extension cords, or inte-
gral convenience receptacles as this can result in a risk of fire or elec-
tric shock.
20. Attachment - Do not use attachments not recommended by the ap-
pliance manufacturer as they may cause hazards.
21. 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.
22. Safety check - Upon completion of any service or repairs to this ap-
pliance, ask the service technician to perform safety checks to deter-
mine that the appliance is in proper operating condition.
