 D. Preparation for Test
 (1)
 Energize the aircraft electrical circuits (Ref. TASK 24-41-00-861-002).

 (2)
 Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. TASK 31-60-00-860-001).

 (3)
 Make sure that the HYD page on the system (lower) display comes on.

 (4)
 Pressurize the reservoir of the Blue hydraulic system (Ref. TASK 29-14-00-614-002).

 (5)
 Make sure that the fluid level in the reservoir of the Blue hydraulic system is correct. Add fluid as necessary (Ref. TASK 12-12-29-611-001).
