safety purpose of the polarized plug. If your unit is equipped with a 3-wire grounding-type plug, having a third (grounding) pin,
this plug will only fit into a grounding-type power outlet. This is a safety feature. 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 so as to
provide some protection against voltage surges and built-up static charges. Section 810 of the National Electric 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 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 the 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 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
When replacement parts are required, be sure the service technician uses replacement parts specified by the manufacturer or
those that 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
unit, ask the service technician to perform safety
checks to determine that the unit is in proper
operating condition.
22. WALL OR CEILING MOUNTING
The product should be mounted to a wall or ceiling
only as recommended by the manufacturer.
23. HEAT
The product should be situated away from heat
sources such as radiators, heat registers, stoves,
or other products (including amplifiers) that
produce heat.
24. 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.
