Binocular Tube (U-BI90, U-TBI90)
Using the Allen screwdriver, loosen the observation tube clamping
screw on the observation tube mount to remove the cap.
Attach the circular dovetail mount of the observation tube into the
observation tube mount, placing the observation tube so that the
interpupillary distance scale numbers are seen right side up. Then
tighten the clamping screw to clamp the observation tube.
} Normally, the distance from the surface of the desk to the eye point
is approximately 430 mm. If it is desirable to lower the eye point
position, the observation tube (provided it is other than the U-TBI90)
may be detached, turned 180° and then attached on the observa-
tion tube mount again. This lowers the eye point height by approxi-
mately 30 mm.

scope.
Tighten the observation tube clamping screw to clamp the interme-
