4 Using Eyepiece Micrometer Disks
(Fig. 12)
Eyepiece micrometer disks can be inserted into WHN10X-H (or WHN10X)
eyepieces.
However, if the eyepiece does not have the helicoid adjustment facility
and your eyesight is poor, you may have difficulties in focusing on the
eyepiece micrometer disk. In this case, it is recommended to look into
the eyepiece through your eyeglasses.
Use 24 mm dia. x 1.5 mm micrometer disks.
Following Fig. 12, remove the micrometer mounting frame ² from the
eyepiece and place a micrometer disk @ into the mounting frame.
Re-attach the micrometer mounting frame in the original position.

Adjusting the Tilt (with the U-TBI3/SWETTR2)
(Fig. 14)
}Adjust the height and tilt of the observation tube to obtain the most com-
fortable viewing position.
Holding the binocular section with both hands, raise or lower it to the
desired position.
#Never attempt to force the binocular section past the upper or lower
stop position. Applying excessive force could destroy the limiting
mechanism.
#The U-TBI3 cannot be used in combination with any intermediate
attachment.
