(9) Release LOCKING LEVER and tighten PIVOT SCREW (if necessary) so

REFERENCE MIRROR will stay in any position without use of LOCKING LEVER (fig. 5).

NOTE

"Out" position means apertures are open for passage of light

from boresight collimator mounting position. "In" position

means apertures are not open for passage of light from

boresight collimator mounting position.

(10) Move REFERENCE MIRROR to out position (fig. 5). Do not use LOCKING

LEVER to lock REFERENCE MIRROR in place (fig. 5).

(11) Look through EYEPIECE (fig. 5), view STATIONARY RETICLE (fig. 6) and its

reflected image. If STATIONARY RETICLE (fig. 6) reflected image is not seen, perform

b (l) through (5) below.

(12) Look through EYEPIECE (fig. 5) and turn FINE ADJUSTMENT SCREWS

(fig. 5) to adjust elevation and azimuth of STATIONARY RETICLE REFLECTED IMAGE

until it is on top of STATIONARY RETICLE (fig. 6).

(13) Release LATCH HANDLES on calibration plate and remove from OPTICS

ASSEMBLY (fig. 6). Return CALIBRATION PLATE ASSEMBLY (fig. 6) to container

case cover.
