Note To The Catv System Installer - Pico Macom PFAM550SUB Installation And Operation Manual

Important Information
10. Grounding or Polarization - This video product is equipped
with either a three prong plug for 110 VAC use or a two prong
flat blade 220 volt type plug. Each type is to be inserted into
only the type of receptacle for which they are specifically
designed . Do not cut off the round grounding pin of a three
prong plug in order to be able to fit into a two prong receptacle
as this could cause injury and will void the warranty.

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 installing an outside antenna system, extreme

circuits as contact with them may be fatal.
