FOCUSING
The eyepieces can be focused by placing the focusing rod in the hole where the lamp and microscope arms rotate.
With the focusing rod in place, adjust the
beam width to give a narrow parallelepiped.
The beam should be in center of your field
of view. If it is not be sure the light tower
rotation is in the click position, center knob
at bottom of light tower near beam width
control. Looking through the eyepieces
(one at a time) rotate the eyepiece
counter-clockwise until the beam is blurred
then clockwise until it just comes into focus.
Remove the focusing rod and you are ready
to examine the patient.
