about 12 o’clock to 3 o’clock range
for phase, 1 o’clock to all the way
up for darkfield. The settings are
specimen and objective

camera default mode is to auto-
adjust for any lighting situation.
Focus knob and stage tension:
The inner
ring on the right focus knob is a stage tension
adjustment. With your fingertips you can rotate
it counter-clockwise to loosen the stage
tension and focus knob. If too loose, the stage
can vertically drift down by itself and that can
be corrected by tightening the tension ring.
Setting a stop point for the stage:
This is the pre-focus/stage stop
adjustment wheel.
