Do not take apart or modify the scanner. The inside of the scanner contains high-
voltage components. Touching these components might cause fire or electric
shock.
To avoid injuries, do not place the scanner in an area where small children may
be able to reach.
Do not use the scanner while driving a car for safety. Accidents can happen.

swimming pool where it may easily get wet or moistured. Doing so might cause
electric shock or fire.
Firmly insert the power plug into the power outlet as far it can go.
