Plugging in the microscope
Always use an appropriate, undamaged, grounded power cord when plugging in your microscope.
Avoid shock hazard.
Use only a 3-wire, grounded power cord appropriate for use in your country.
Do not, under any circumstances, cut or remove the ground prong from the power cord or use an adapter.
Regularly inspect the power cord for signs of damage and replace the power cord if it becomes damaged.
