NOTE
If it is not possible to roll in reticle, position of focusing lens relative to optical-mechanical axis of AS-2 has
been disturbed due to mishandling. Refer to higher level maintenance.
(42)
Adjust focusing knob of AS-2 until image of 16 ft reticle of MTC becomes sharp.
(43)
Adjust AS-2 until two reticle images are in vertical and horizontal register.
(44)
Rotate AS-2 180° in its mount. Check for out-of-register condition in vertical wire only.
(45)
Adjust focusing knob of AS-2 until 4 ft reticle of MTC is sharp and repeat steps (43) and (44).
NOTE
Reticles must be in adjustment before attempting to adjust autoreflection target.
(46)
Place stellite mirror on adjustable mirror mount in front of MTC.
(47)
Turn on light to AS-2.
(48)
Turn focusing knob slowly until autoreflection target comes into sharp focus. This will occur when AS-2 is
focused to a distance equal to twice the distance of autoreflection target to mirror.
(49)
Adjust either mirror or AS-2 until reticle image is centered on cross of autoreflection target pattern.
(50)
Rotate AS-2 180° in its mount and check for out-of-register condition of vertical pattern only. If out-of-register
condition is present remove one-half error using horizontal autoreflection target adjustment screws. Remove remaining
error using tangent screws of mount supporting AS-2.
(51)
Rotate AS-2 180° in its mount and verify adjustment. Continue rotating 180° and adjusting until vertical patterns
remain in register.
(52)
Rotate AS-2 90°and repeat steps (49) thru (51) until vertical pattern is in register.
(53)
Bring both vertical and horizontal patterns into register and again rotate AS-2 180. If adjustment is complete,
patterns should remain in exact register both vertically and horizontally. If they do not, rotate AS-2 90° and repeat steps
(48) thru (52) until they remain in register.
