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, conve-

nience 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 

circuits, where it can fall into such power lines or circuits. When install-

ing 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.

Overloading:

 Do not overload wall outlets and extension cords as 

this can result in risk of fire or electric shock.

Outdoor Antenna Grounding:

 Before attempting to install this 

product, be sure the antenna or cable system is grounded so as to 

provide some protection against voltage surges and built-up static 

charges.

 

 a.

 Use No.10 AWG (5.3mm) copper, No.8 AWG (8.4mm) 

aluminum, No.7 AWG (10mm) copper-clad steel or bronze wire 

or larger, as ground wire.

 

 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.

 

 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.

  Use jumper wire not smaller than No.6 AWG (13.3mm) copper
