ELNA EnVision 8006 Instruction Manual page 60

OPERATING INSTRUCTIONS:
The symbol "O" of a switch indicates the "off" position of a switch.
For appliances with a polarized plug(one blade wider the other).
To reduce the risk of electric shock, this plug is intended to 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 modify the plug in any way.
