Attaching the observation tube
If the eyepieces are attached to the observation tube, remove the eyepieces
before attaching the observation tube.
Loosen the clamping screw a of the microscope frame until the
clamping screw is hidden looking from above (until there is no feeling
of protrusion when touched by fingers).
Insert the circular dovetail b of the observation tube under the
protrusions c (2 positions) on the mount of the microscope frame.
Adjust the direction of the observation tube so that the value of the
interpupillary distance adjustment scale on the observation tube faces
to the front, and tighten the clamping screw d of the standard arm
to secure it.
If the observation tube moves when you attempt to rotate
it, the observation tube is not fixed properly. Tighten the
clamping screw again.
