8. Dc Module Check
a. Performance Check
(1) Close and latch TI test chamber cover. Remove any batteries from PRC-90/106
battery chamber.
(2) Connect dc power supply to EXT. PWR PRC-90/106 (fig. 1) test points.
NOTE
Monitor dc power supply with multimeter (dc mode).
(3) Connect calibration plug to TI connector 2J1 on right side of dc module.
(4) Adjust dc power supply for a 10.90 V dc indication on multimeter.
(5) The TI BATTERY VOLTAGE PASS indicator must be illuminated and the
FAIL indicator must be off; if not perform b (1) below.
(6) Adjust dc power supply for a 10.70 V dc indication on multimeter.
