(2) Check to be sure that 7.62 appears in the status indicator
(figure 15).
If it does not appear in the status indicator,
troubleshooting
must
be
performed
to
isolate
the
problem.
Troubleshooting procedures can be found in TM 9-2350-252-20-2-1,
chapter 3. If 7.62 does appear in the status indicator, boresighting
can continue.

CHECKING THE STATUS INDICATOR AND GUN RETICLE.
(3) Check the alignment of the gun reticle (figure 15) on the
aiming point of the target.
It should be aligned.
If it is not
aligned on the aiming point of the target, troubleshooting must be
performed to isolate and correct the problem.
Troubleshooting
procedures can be found, when needed, in TM 9-2350-252-20-2-1,
chapter 3. If the reticle is aligned, boresighting can continue.
(4) It will now be necessary for the helper to move to the
commander's seat. Since the coaxial machinegun is boresighted on the
same target as the 25mm gun, be careful not to move the handwheels or
controls while moving to the commander's station.
