constitute a risk of electric shock to persons.
This symbol is intended to alert the user to the presence
of important operation and maintenance (servicing)
instructions in the literature accompanying the appliance.
To prevent electric shock do not use this (polarised) plug
with an extension cord, receptacle or other outlet unless
