13. LIGHTNING
To protect your product 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 product
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 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
Never push objects of any kind through openings in the product 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.
17. 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 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 grounding electrodes.
18. SERVICING
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.
19. 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.
20. 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 operating condition.
21. WALL OR CEILING MOUNTING
The product should be mounted to a wall or ceiling only as recommended by the manufacturer.
22. DAMAGE REQUIRING SERVICE
Unplug the product 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 product.
c. If the product has been exposed to rain or water.
d. If the product does not operate normally after installation by following the operating instructions. Adjust only those
controls that are covered by the operating instructions, as adjustment of other controls may result in damage and
will often require extensive work by a qualified technician to restore 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.
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.
