lary distance by turning the two parts until one
circle of light can be seen. (Fig. 7)

• Highpoint eyepieces allow the use also to glass
wearers.

using your glasses during normal microscope use

The coarse knob tension is pre-setted in the factory.
1. To modify the tension according to personal's
needs, rotate the ring ③ using the provided tool
(Fig. 9).
• Clockwise rotation increases the tension.

lower by itself or the focus easily lost after fine
adjustment. In this case, rotate the knob in order
