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.
