16. 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.
17. Overloading.
Do not overload wall outlets and extension cords as this can result in a risk of fire or electric shock.

Never push objects of any kind into this product through openings 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 on the product.
19. Outdoor antenna grounding.
If an outside antenna is connected to the product, be sure the antenna 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 to grounding of the mast and supporting structure,
grounding of the lead-in wire to an antenna discharge product, size of grounding conductors, location of
antenna-discharge product, connection to grounding electrodes and requirements for the grounding electrodes.
20. Service.
Do not attempt to service this product yourself as opening
or removing covers may expose you to
dangerous voltage or other hazards. Refer all
servicing to qualified service personnel.
21. 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 parts. Unauthorized substitutions may
result in fire or electric shock or other hazards.
22. Safety check.
Upon completion of any service or repairs to this product, ask the service technician to perform safety
checks to determine that the product is in proper operation condition.
23. Wall or ceiling mounting.
The product should be mounted to a wall or ceiling only as recommended by the manufacturer.
24. Damage requiring service.
Unplug this product from the wall outlet and refer service 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 product.
c) If the product has been exposed to rain or water.
d) If the product 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 and require extensive work by a qualified technician to restore in the product to its normal operation.
e) If the product has been dropped or the cabinet has been damaged.
f) When the product exhibits a distinct change in performance-this indicates a need for service.
25. 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.
NOTE: Refer all servicing to qualified service personnel. Servicing is required when the unit has been
damaged in any way such as the following: the power-supply cored or plug has been damaged, liquid has
been spilled into the unit, the unit has been exposed to rain or moisture, the unit has been dropped or
the unit does not operate normally.
