(Ref. ASM 35-23/01).
(2) If the fault continues:
- Do the operational test of the annunciator light test system (Ref. AMM TASK 33-14-00-710-001).
(a) If the test gives a different maintenance message:
- Do the trouble shooting procedure related to the maintenance message.
C. If the FAULT legend on the pushbutton switch OXYGEN/TMR RESET, which is installed on the panel 50VU, comes on and goes off after pushing the OXYGEN/MASK MAN ON pushbutton switch:
- Do a check of the RELAY-TIME DELAY (15WR) and replace it if necessary (Ref. ASM 35-23/01).
