2. Insert two AA batteries, as directed in the compartment's bottom.
3. Put back the protecting screw.
4. Lift the nose piece as much as possible with the upper wheel.
5. Put a slide with the tissue or organism you want to observe on the tray, fixed under the two blockers.
6. Point the light up, and switch it on.
