Note:
The eyepiece’s aperture protector must be re-
moved or folded back, during microscopy while
wearing eyeglasses.
We recommend that users take off glasses with
bifocal or progressive-addition lenses when
working with the microscope.
• For the adjustable tubes with documentation
output, choose the 100% VIS position.
Eyepieces with Inlaid Reticle
• Focus the reticle by adjusting the eye lens.
• Focus on the object through this eyepiece.
• Then, close that eye and focus on the object
by adjusting only the second ocular.
Correction for Vision Problems
• With your right eye, look through the right
eyepiece and bring the specimen into sharp
focus.
• Then, with your left eye, view the same
specimen and rotate the left eyepiece tube
until the object is brought into sharp focus.
Do not use the focus dial.
