prong. These are provided for your safety. Do not defeat grounding
and/or polarization safety provisions. If the supplied plug does not
fit your outlet, please consult an electrician for replacement of the
obsolete outlet. Do not use extension cords.

unplugged from the mains (AC) outlet. The stand-by LED indicator
will not be lit up to show the power cord is unplugged. The disconnect
device shall remain readily operable.
Do not route the power cord where it will be crushed, pinched, bent,
exposed to heat, or damaged in any way. Pay particular attention to the
power cord at the plug and where the cord exits the back of the unit.
The power cord should be unplugged from the wall outlet during a
lightning storm or if the unit is to be left unused for a long period
of time.
This apparatus shall be connected to a main socket outlet with a
protective earth connection.
