2.While wearing your glasses, look through the eyepieces and focus on the specimen.

3.Rotate both eyepieces to the maximum value of "+5".

4.Hold one eye closed and rotate the other eyepiece in "-" direction until the specimen appears sharp.

5.Then, open the other eye and correct the diopter settings until the image is uniformly sharp.
