CARING FOR YOUR MICROSCOPE: Your microscope is a precision optical instrument and when treated

with care, should provide years of use. Here are a few tips to keep your microscope in top shape:

• Always carry the microscope with two hands.

• Always remove slides from the stage before putting the microscope away.

• Cover the microscope or store it back in the box when not in use.

• Use lens cleaning tissue ONLY when cleaning the lenses.

• Never allow the objective lenses to touch the slide or the stage.

• Remove the batteries before storing the microscope for extended periods of time

(30 days or longer).
