List steps on how to properly use microscope 8 steps

1. Always carry the microscope with one hand on the arm and the other hand under the base.

2. Wrap the microscope cord and place in a 3×3×3×4 configuration in the cabinets if in E-316 or E-317

3. Never let electrical cord drop down from the bench top

4. Never use the high power objectives without immersion oil

5. Always begin focusing with the scanning objective in place and the stage all the way down

6. Never adjust the coarse adjustment knob at higher objectives

7. Only use lens paper and cleaner on the microscope slides, objectives, ocular lenses
