NOTE: If data displays were checked on only one INS during insertion,
____ check displays individually on other CDU's by setting data selector to WAYPT and waypoint selector to each position for which data was inserted. If incorrect data is displayed, reload (remotely) again until data is correct.
(4) Check INS Status (All INS)
(a)
Press REMOTE key on each CDU and observe that REMOTE key light goes out on all INS.
(b)
Place data selector to DSRTK/STS and observe that three digits appear in right-hand display. (See figure 501.) The fifth digit from the left indicates the align mode number during the align mode. The sixth digit is set to 5 during ALIGN and cannot be changed during the align mode.
