A. If the DEU-B 300RH5 failure message comes on:
- replace the DEU-B (300RH5) (Ref. AMM TASK 23-73-47-000-001) and (Ref. AMM TASK 23-73-47-400-001).
NOTE : If no spare DEU-B is available and to avoid AOG due to two
____ inoperative ATTND stations it is possible to swap DEU-B 300RH5 with DEU-B 300RH4. Ignore the SLIDE PRESS LOW message on the PTP generated by the swapped faulty DEU-B 300RH5. To make sure that the pressure gage of the RH offwing slide inflation-reservoir is in the correct range do the Inspection/Check procedure of the offwing slide inflation-reservoir (Ref. AMM TASK 25-62-00-210-001).
