Resetting The Height
Adjustment Handle
After a period of use, the spring tension on the height
adjustment may loosen so that the colposcope head falls
by itself. In this case, readjust as follows:
1. With the colposcope head extended out of the inser-
tion tube, lift the cap (A).
2. Under the cap are 2 leaf springs (B) fixed with 4
screws. Tighten these screws evenly so that the
small brass wheel (C) fits on the driving shaft (D) and
does not slide.
3. Verify that the wheel and notch in the driving shaft
are free of dirt and grease. Clean these parts with
alcohol.
Slide the cap (A) until it snaps back into place.
