What Happened Why What To Do
Nothing happens when
the power switch is
turned on (i.e., power
indicator does not
illuminate or there is
nothing on the display).
Power cord is not fully
inserted at one end or the
other.
Insert the power plug firmly into the
outlet socket; insert unit connector
firmly into power connector opening.
No power at the outlet. Plug in a lamp or small appliance to test
the outlet. If there is no power, contact
electrician.
