. Power Source—The unit should be connected to power supply
only of the type described in the operating instructions or as
marked on the unit.
. Polarization—If the unit is equipped with a polarized AC power
plug (a plug having one blade wider than the other), that plug will
fit into the AC 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 should still fail to fit, contact your electrician to
replace your obsolete outlet. Do not defeat the safety purpose of
the polarized plug.
. Power Cord Protection—AC
power supply cords should be
routed so that they are not likely to be walked on or pinched by
items placed upon or against them. Never take hold of the plug or
cord if your hand is wet, and always grasp the plug body when
connecting or disconnecting it.
. Nonuse Periods—When the unit is not used, turn the power off.
When left unused for a long period of time, the unit should be
