Adjusting the Tilt
(Fig. 19)
}When using the tilting binocular tube, adjust the height and tilt of the
observation tube to obtain the most comfortable viewing position.
Holding the binocular section with both hands, raise or lower it to the
desired position.
· U-CTBI/CKX-TBI: 30 to 60°
· U-TBI3: 5 to 35°
#Never attempt to force the binocular section past the upper or lower
stop position. Applying excessive force could destroy the limiting
mechanism.
#Tilt adjustment is possible with specified eyepieces. Combination
with any other eyepiece will result in insufficient illumination at the
periphery of the field of view.
· U-CTBI/CKX-TBI: Provided eyepieces only.
· U-TBI3: WHN10X only.
When adjusting the tilt of the U-CTBI, be careful not to have your
fingers caught by the spaces @ between the binocular assembly
and cover.
