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

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

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.
