TYPES 7603 AND 7603N OPT 115
6. Preliminary Instructions
a. The instructions outlined in paragraphs 6 and 7 preparatory to the calibration
process. Personnel should become familiar with the entire bulletin before beginning the
calibration.
b. Items of equipment used in this procedure are referenced within the text by
common name and item identification number as listed in table 2.
c. Unless otherwise specified, verify the result of each test and, whenever the test
requirement is not met, take corrective action before continuing with the calibration.
Adjustments required to calibrate the TI are included in this procedure. Additional
maintenance information is contained in the manufacturer's manuals and TM 11-6625-
2658-14 for these TIs.
d. When indications specified in paragraphs 8 through 12 are not within tolerance,
perform the power supply check prior to making adjustments. After adjustments are
made, repeat paragraphs 8 through 12. Do not perform power supply check if all other
parameters are within tolerance.
e. Unless otherwise specified, all controls and control settings refer to the TI.
