10. POWER SOURCES
This unit should be operated only from the type of power source indicated on the rating plate. If you are not sure of the type of power supply to your
home, consult your appliance dealer or local power company. For units intended to operate from battery power, or other sources, refer to the operating
instructions.
11. GROUNDING OR POLARIZATION
This unit is equipped with a polarized alternating current line plug (a plug having one blade wider than the other). This plug will fit into the power outlet
only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit,
contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug, if your unit is equipped with a 3-wire
grounding-type plug, a plug having a third (grounding) pin. This plug will only fit into a grounding-type power outlet. This too, is a safety feature. If you
are unable to insert the plug into the outlet, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the grounding
type plug.
12. POWER-CORD PROTECTION
Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular
attention to cords at plugs, convenience receptacles, and the point where they exit from the appliance.
13. LIGHTNING
To protect your unit from 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 unit due to lightning and power line surges.
14. 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.
15. OVERLOADING
Do not overload wall outlets and extension cords, as this can result in a risk of fire or electric shock.
16. OBJECT AND LIQUID ENTRY
Do not push objects through any openings in this unit, as they may touch dangerous voltage points or short out parts that could result in fire or electric
shock. Never spill or spray any type of liquid into the unit.
17. OUTDOOR ANTENNA GROUNDING
If an outside antenna or cable system is connected to the unit, be sure the antenna or cable system is grounded to provide some protection against
voltage surges and built-up static charges, Section 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.
18. SERVICING
Do not attempt to service this 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 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 liquid has been spilled, or objects have fallen into the unit.
c. If the unit has been exposed to rain or water.
d. If the 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 unit to its
normal operation.
e. If the unit has been dropped or the cabinet has been damaged.
f. When the unit exhibits a distinct change in performance, this indicates a need for service.
20. REPLACEMENT PARTS

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 unit, ask the service technician to perform safety checks to determine that the unit is in proper
operating condition.
22. HEAT

23. NOTE TO CATV SYSTEM INSTALLER
This reminder is provided to call the CATV system installer’s attention to Article 820-40 of the NEC that provides guidelines for proper grounding and, in
particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical.
