−
This unit may be
equipped with a polarized alternating current line plug (a plug with one
blade wider than the other). This safety feature allows the plug to fit into
the power outlet in only one way. If unable to insert the plug fully into the
outlet, try reversing the plug. If the plug still fails to fit, contact an
electrician to arrange replacement of the obsolete outlet. Do not defeat the
safety purpose of the polarized plug. Alternately, this unit may be equipped
with a 3
−
wire grounding plug (a plug with a third pin, for grounding). This
safety feature allows the plug to fit into a grounding power outlet only. If
unable to insert the plug into the outlet, contact an electrician to arrange
