cuits, orwhere it can fall into such power lines or circuits. When in-

stalling an outsideantenna system, extreme care should be taken to 

keep from touching suchpower lines or circuits, as contact with them 

might be fatal.

thatyour  service  technician  has  used  replacement  parts  specified 

by the manufactureror have the same characteristics as the original 

part. Unauthorizedsubstitutions may result in fire, electric shock, or 

other hazards.

22. Safety Check: Upon completion of any service or repairs to this 

product,ask the service technician to perform safety checks to ensure
