* Hint:
Tightening the clipping knob fixes the rotary ring

When it is completely tightened, the collimator
attached to the rotar ring is at right angles to the

try tightening the clipping knob to compensatefor

On the other hand, if the collimator can be
attached to the cam-corder, try loosening the
clipping knob slightly to make a little room
around the clipping knob.
