Viewing Tube Adjustment
Adjust the eyetubes
1.Adjust the tubes to your interpupillary distance. Fold or unfold the eyetubes to decrease or increase the distance between the eyepieces until you see one illuminated circle.
The viewing tubes maintain a constant tube length for all interpupillary settings.
This means that a change of interpupillary distance does not affect parfocality, magnifica- tion, or calibrations that depend on magnifica- tion.
