d. Rotate the nosepiece so that you view the slide through the 10X objective, then the 40X objective. Focus using the fine focus knob.
e. From the 40X objective, rotate the nosepiece slightly toward the 100X objective. Neither the 40X nor the 100X objectives should be in place.
f. Place one small drop of immersion oil on the slide. Rotate the nosepiece so that the 100X objective is in place.
g. Focus on the slide, using only the fine focus knob.
Note:After the 100X objective is in place and oil is on the slide, you may not view the slide with other objectives. You must first clean the slide and the 100X objective.
