TO USE AC POWER SOURCE
AC Outlet
_ IIWiderHOle _
Polarized AC Cord Plug
(One blade is wider than the other.)
Use the AC polarized line cord provided for operation on AC. Insert
the AC cord plug into a standard 120V 60Hz polarized AC outlet.
Notes:
• Never connect the AC line cord plug to other than the specified
voltage (120V 60Hz). Use the attached power cord only.
• If the polarized AC cord does not fit into a non-polarized AC
outlet, do not attempt to file or cut the blade. It is the user's
responsibility to have an electrician replace the obsolete outlet.
• If you cause a static discharge when touching the unit and the
unit fails to function, simply unplug the unit from the AC outlet
and plug it back in. The unit should return to normal operation.
• If the AC cord plug is plugged in for the first time, wait for about 5
seconds before pressing the power button on the front panel.
