Assembly for the triple-viewing model

Assemble the system in the order of the numbers ([1] to [9]) in the figure below.
 Check that the serial numbers on the two components (on the main section and the relay section) of the MTH
relay unit are identical. (If the numbers are different, observation will be adversely affected. In this case, please
contact your dealer or nearest Nikon representative.)
 Adjust the height of the support stand so that the main observer section and the secondary observer section
are horizontal. This step is facilitated by first adjusting the support stand to an approximate height before
attaching the stand.
 In the illustration below, the secondary observers are positioned on the right side of the main observer, but they
may also be positioned on the left. Attach the MTH main splitter so that the pointer mounting surface is facing
towards the front.

Remarks
If a trinocular eyepiece tube T is used for the main observer section, you can provide the image to the
vertical tube of the eyepiece tube by setting the optical path to the "BINO & PHOTO" position. If the ND
filter is removed in advance from the eyepiece tube mounting port of the MTH main splitter, the main and
the secondary observers will be able to view an image with more uniform brightness. This should be
convenient such as when performing the TV observation.
