11. Grounding or Polarization — This video unit may be
equipped with either a polarized 2-wire AC
(Alternating Current) line plug (a plug having one
blade wider than the other) or 3-wire grounding type
plug, a plug having a third (grounding) pin.
The 2-wire polarized 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 still fails to fit, contact
your electrician to replace your obsolete outlet. Do
not defeat the safety purpose of the polarized plug.
The 3-wire grounding type plug will fit into a

If you are unable to insert the plug into the outlet,
contact your electrician to replace your obsolete
outlet. Do not defeat the safety purpose of the
grounding type plug.
