10. Grounding or Polarization -
This video product is equipped
with a polarized alternating - current line plug (a plug having one
blade wider than the other). This plug will fit into the power
socket 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 polarized
plug.
