IMPORTANT SAFETY INSTRUCTIONS (CONTINUED)
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 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
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.
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 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 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.
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.
