Using a hexagonal screwdriver, slacken the
clamp screw (20.1, 21.1, 22.1) on the side of the
tube change mount on the stand and remove the
black cap.
Mount the tube so that the guide pin snaps in
position and the Siedentopf binocular element
(20.3, 21.3, 22.3) points upwards as a V shape.
Retighten the clamp screw. Hold on to the tube
until the clamp screw is tightened as otherwise it
might fall off.
Insert the eyepieces into the tube ports as far as
the stops.
Insert the eyepiece with adjustable eyelens into
the right-hand port, where it is easier to handle.
