Important Safeguards
13. Outdoor Antenna Grounding — If an outside
antenna or cable system is connected to the
video unit, be sure the antenna or cable
system is grounded so as to provide some
protection against voltage surges and built-
up static charges. Part 1 of the Canadian
Electrical Code, in USA Section 810 of the
National Electrical Code, 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.
14. Lightning — For added protection of this
video unit receiver 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
video unit due to lightning and power-line
surges.
15. 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.
16. Overloading — Do not overload wall outlets
and extension cords as this can result in a
risk of fire or electric shock.
17. Objects and Liquids — Never push objects
of any kind into this video unit through
openings as they may touch dangerous
voltage points or short out parts that could
result in a fire or electric shock. Never spill
liquid of any kind onto the video unit.
18. Servicing — Do not attempt to service this
video unit yourself as opening or removing
covers may expose you to dangerous
voltage or other hazards. Refer all servicing
to qualified service personnel.
19. Damage Requiring Service — Unplug this
video unit from the wall outlet and refer
servicing to qualified service personnel
under the following conditions:
a. When the power-supply cord or plug is
damaged.
b. If any liquid has been spilled onto, or
objects have fallen into the video unit.
c. If the video unit has been exposed to rain
or water.
d. If the video unit does not operate normally
by following the operating instructions.
Adjust only those controls that are
covered by the operating instructions, as
an improper adjustment of other controls
may result in damage and will often
require extensive work by a qualified
technician to restore the video unit to its
normal peration.
e. If the video unit has been dropped or the
cabinet has been damaged.
f. When the video unit exhibits a distinct
change in performance – this indicates a
need for service.
20. 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 part.
Unauthorized substitutions may result in fire,
electric shock or other hazards.
21. Safety Check — Upon completion of any
service or repairs to this video unit, ask the
service technician to perform safety checks
to determine that the video unit is in safe
operating order.
FCC Warning: Any unauthorized changes or modifications to this equipment would void the user’s
authority to operate.
