11. Power Sources: This product should be operated only from the  
type of power source indicated on the marking label. If you are not  
sure of the type of power supplied to your home, consult your appli-  
ance dealer or local power company.  
12. Power-cord Protection: Power-supply cords should be routed  
so they are not likely to be walked on or pinched by items placed upon  
or against them. Pay particular attention to cords and plugs, conven-  
ience receptacles, and the point where they exit from the appliance.  
13. Lightning: For added protection for this product during a lightning  
storm, or when it is left unattended or unused for long periods of time,  
the unit should be disconnected from power source.  
14. Power Lines: An outside antenna system should not be located  
in the vicinity of overhead power lines, other electric light or power cir-  
cuits, 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 may  
be fatal.  
15. Overloading: Do not overload wall outlets and extension cords as  
this can result in 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 a fire or electric shock.  
Never spill liquid of any kind on the product.  
17. 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.  
18. Damage Requiring Service: Unplug this product from the wall  
outlet and refer servicing to qualified service personnel under the fol-  
lowing conditions:  
provide some protection against voltage surges and built-up static  
charges.  
a. Use No.10 AWG (5.3mm) copper, No.8 AWG (8.4mm) alu-  
minum, No.7 AWG (10mm) copper-clad steel or bronze wire or  
larger, as ground wire.  
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.  
b. Secure antenna lead-in and ground wires to house with stand-  
off insulators spaced from 4 feet (1.22m) to 6 feet (1.83m) apart.  
d. If the product does not operate normally by following the oper-  
ating instruction. Adjust only those controls that are covered by  
the operating instructions. An improper adjustment may result in  
damage and will often require extensive work by a qualified tech-  
nician to restore the product to its normal operation.  
c. Mount antenna discharge unit as close as possible to where  
lead-in enters house.  
d. A driven rod may be used as the grounding electrode where  
other types of electrode systems do not exist. Refer to the  
National Electrical Code, ANSI/NFPA 70-1984 for information.  
e. If the product has been dropped or the cabinet has been  
damaged.  
e. Use jumper wire not smaller than No.6 AWG (13.3mm) copper  
or equivalent, when a separate antenna grounding electrode is  
used.  
f. When the product exhibits a distinct change in performance—  
this indicates a need for service.  
19. Replacement Parts: When replacement parts are required, be  
sure the service technician has used replacement parts specified by  
the manufacturer or have the same characteristics as the original  
parts. Unauthorized substitutes may result in fire, electric shock or  
other hazards.
