(16) Look through EYEPIECE and ensure STATIONARY RETICLE REFLECTED

IMAGE (fig. 6) is visible. If STATIONARY RETICLE REFLECTED IMAGE (fig. 6) is not

visible, perform b (6) through (9) below.

(17) Rotate SMALL CENTER MICROMETER HORIZONTAL and VERTICAL

CONTROLS (fig. 3) until VERTICAL AND HORIZONTAL BIFILARS are aligned with

STATIONARY RETICLE REFLECTED IMAGES (fig. 6).

(18) Hold SMALL CENTER HORIZONTAL and VERTICAL CONTROLS and rotate

OUTER MICROMETER HORIZONTAL and VERTICAL CONTROLS until 30 is indicated

in HORIZONTAL and VERTICAL VIEWERS (fig. 3).

(19) Verify that HORIZONTAL and VERTICAL BIFILARS (fig. 6) remain aligned

with stationary reticle reflected images with 30 indicated in HORIZONTAL and VERTICAL

(20) Rotate SMALL CENTER MICROMETER HORIZONTAL and VERTICAL

CONTROLS (fig. 3) to move HORIZONTAL and VERTICAL BIFILARS (fig. 6) so that

stationary reticle reflected image can be seen without obstruction.

(21) Move MIDDLE MIRROR OPTICAL BAFFLE (fig. 8) to open position.
