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 infor-
mation 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 dis-
charge 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 touch-
ing 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 qual-
ified service personnel under the following condi-
tions:
a. When the power-supply cord or plug is dam-

aged.

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 operation.

e. If the video unit has been dropped or the cabi-

net has been damaged.

f. When the video unit exhibits a distinct change in 

performance — this indicates a need for ser-

vice.

20. Replacement Parts — When replacement parts 

are required, be sure the service technician has 
used replacement parts specified by the manufac-
turer or have the same characteristics as the origi-
nal 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 techni-
cian to perform safety checks to determine that the 
video unit is in safe operating order.
