b. Adjustments. No adjustments can be made.
13. Final Procedure
a. Deenergize and disconnect all equipment and reinstall protective cover on TI.
b. When all parameters are within tolerance, annotate and affix DA Label 80 (U.S.

annotate and affix DA Label 163 (U.S. Army Limited or Special Calibration). When the TI
cannot be adjusted within tolerance, repair the TI in accordance with the maintenance
