Adjusting the Interpupillary Distance
(Figs. 8 to 10)
With the CKX31
While looking through the eyepieces, move both eyepieces until the left
and right fields of view coincide completely.
Adjust so that the two index dots ·
1
are horizontal. (Fig. 9)
}To make the line connecting the two index dots horizontal, adjust so that
the index dots come on the extension of one of the horizontality lines
inscribed on the pivot.
When your interpupillary distance is other than 50, 60, 70 and 75, adjust
so that the line connecting the two index dots are in parallel with the
horizontality lines on the pivot. (Fig. 9)
}Note your interpupillary distance so that it can be quickly duplicated.
With the CKX41
}When the observation tube is the U-CBI30-2, U-CTR30-2 or U-CTBI, fol-
low the procedure in "With the CKX31".
}When the observation tube is the U-BI30-2, U-TR30-2 or CKX-TBI only
one index dot is provided. (Fig. 10)
· While looking through the eyepieces, move both eyepieces until the left
and right fields of view coincide completely. The position of index dot ·
indicates the interpupillary distance.
}Note your interpupillary distance so that it can be quickly duplicated.
@
When adjusting the interpupillary distance, take care not to let your
fingers get caught in the gaps of the binocular section.
