A. Aircraft Maintenance Configuration
(1) Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).
(2) On the panel 400 VU, make sure that the landing gear control-lever is in the DOWN position.
(3) Do the EIS Start procedure (Ref. AMM TASK 31-60-00-860-001).
Subtask 32-47-00-865-050-A (1) Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).
(2) On the panel 400 VU, make sure that the landing gear control-lever is in the DOWN position.
(3) Do the EIS Start procedure (Ref. AMM TASK 31-60-00-860-001).

|---|---|
| On the ECAM control panel: | |
| - on the lower ECAM DU, the WHEEL page comes into view. Make sure that the temperatures shown relate to the ambient temperature with a precision of plus or minus 25 deg.C (45 deg.F). NOTE: In case of negative temperatures, or temperatures near 0 deg.C (32 deg.F), the indication on the display unit ranges from 0 deg.C to 25 deg.C (32 deg.F to 77 deg.F) approximately. |
B. Aircraft Maintenance Configuration
(1) Do the EIS stop procedure (Ref. AMM TASK 31-60-00-860-002).
(2) De-energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-862-002).
5. Close-up(1) Do the EIS stop procedure (Ref. AMM TASK 31-60-00-860-002).
