Electrical Safety
We strongly di_ourage the use of an adapter due to potential sdety hazards.
For temporary connections, use only a UL-][sted adapter, avaiiaibie from most
local hardware stores. Ensure that the large slot in the adapter is aligned with
the large slot in the receptacle for a proper polarity connection.
To disconnect the power cord from the adapter, use one hand on each to avoid
damaging the ground terminal. Avoid frequently unplugging the power cord as
this can lead to eventual ground terminal damage.
