(15)
Rotate AS-1 180° in its mount. Check for out-of-register condition of vertical wire images only.
NOTE
If out-of-register condition exists with either the 16 ft or 4 ft reticle, there may be error in focusing lens
and/or objective lens positioning. Adjustment of such error is complex and should be referred to higher
level maintenance for adjustment.
(16)
Adjust focusing knob of AS-1 until 4 ft reticle of MTC is sharp, and repeat steps (14) and (15).
NOTE
Reticles must be in adjustment before attempting to adjust autoreflection target.
(17)
Place stellite mirror on adjustable mirror mount in front of MTC.
(18)
Turn on light to AS-1.
(19)
Turn focusing knob slowly until autoreflection target comes into sharp focus.
(20)
Adjust either mirror or AS-1 base until reticle image is centered on cross of autoreflection target pattern.
(21)
Rotate AS-1 180° in its mount, and check for out-of-register condition of vertical pattern only. If out-of-register
condition is present, remove one-half the error using horizontal autoreflection target adjustment screws. Remove
remaining error using tangent screws of mount supporting AS-1.
(22)
Rotate AS-1 180 in its mount and verify adjustment. Continue rotating 180 and adjusting until vertical patterns
remain in register.
(23)
Rotate AS-1 90 . Repeat steps (21) and (22) until vertical pattern is in register.
(24)
Bring both vertical and horizontal patterns into register, and again rotate AS-1 180 . If adjustment is complete,
patterns should remain in exact register both vertically and horizontally. If they do not, rotate AS-1 90 , and repeat steps
(20) through (23) until they remain in register.
