FIGURE 11.
ALIGNING THE ELEVATION AND
AZIMUTH CROSSHAIRS.
(20) The next step is aligning the azimuth crosshair in the
boresight reticle on the aiming point of the target (figure 11).  To
accomplish this, the turret is manually traversed, as needed.
(21) Now that the boresight reticle is aligned, the accuracy of
the boresight telescope must be checked.
To do this, rotate the
boresight telescope 90 to the right, and look at the aiming point in
the boresight reticle.  Then rotate the boresight telescope 90 to the
left and look at the aiming point in the boresight reticle.
The
aiming  point  should  stay  in  the  inner  ring  (figure  12  on  the
following page) of the boresight reticle.  If the aiming point moved
out  of  the  inner  ring  of  the  boresight  reticle,  the  boresight
telescope  is  not  accurate.
When  this  happens,  insert  another
boresight  telescope  and  repeat  steps  (17)  through  (21)  of  this
procedure.
If the aiming point stayed in the inner ring of the
boresight reticle for both rotations, continue with boresighting.
(22) Once it has been established that the boresight telescope
is  accurate,  the  focus  barrel  must  be  turned  to  focus  the  gun
reticle.
The boresight reticle and the gun reticle must be focused
on the same aiming point of the target.
