products intended to operate from battery power, or other sources, refer to the 

operating instruction.

12.  Grounding or Polarization - This product may be equipped with a polarized 

alternating-current line plug (a plug having one blade wider than the other). 

This plug will fit into the power outlet only one way. This is a safety feature. If 

you are unable to insert the plug fully into the outlet, try reversing the plug. If 

the plug should still fail to fit, contact your electrician to replace your obsolete 

outlet. Do not defeat the safety purpose of the polarizes plug.

plug is required, be sure the service technician has used a replacement plug 

specified by the manufacturer that has the same overload protection as the 

original plug.

15.  Outdoor Antenna Grounding - If an outside antenna is connected to the 

receiver, be sure the antenna system is grounded so as to provide some 

protection against voltage surges and built-up static charges. Article 810 of the 

National Electrical Code, ANSI/NFPA 70, provides information with regard 

to proper grounding of the mast and supporting structure, grounding of the 

mast and supporting structure, grounding of the lead-in wire to an antenna-

discharge unit, size of grounding conductors, location of antenna-discharge 

unit, connection to grounding electrodes, and requirements for the grounding 

electrode.

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. 

17.  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.

18.  Overloading - Do not overload wall outlets, extension cords, or integral 

convenience receptacles as this can result in a risk of fire or electric shock.
