Panasonic MC-4620 Operating Instructions Manual page 5

THIS VACUUM CLEANER IS INTENDED
To reduce the risk of electric shock, this vacuum cleaner has a polarized
plug (one blade is wider than the other). This plug will fit in a polarized
outlet only one way. If the plug does not fit fully in the outlet, reverse
the plug. If it still does not fit, contact a qualified electrician to install the
proper outlet. Do not change the plug in any way.
Notice
Before you plug in your Panasonic Vacuum Cleaner, make sure that the
voltage indicated on the rating plate located at the back of the vacuum
cleaner is the same as your local supply.
