You need to store the microscope in the correct fashion. Turn the rheostat to 1and then toggle the light off. Turn the nosepiece to the 4X objective and raise the stage to a high position. Wrap the electrical cord snugly around the arm and then lower the stage to help hold the cord in place. Using both hands to carry the scope, return it to the numbered slot in the microscope cabinet.
