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.
