             Note:           During the system power-up sequence, the diagnostic LED does illuminate briefly.
                             This is a normal indication that the system is functioning properly.

             (a)  Set BAT 1 switch to ON position.
             (b)  Open center armrest console, and remove glove box trim. (Refer to 25-10)
             (c)  Locate diagnostic LED, and observe if illuminated.
             (d)  If LED is not illuminated, the system is functioning properly.
             (e)  If LED is illuminated, the data transfer unit is not receiving communications from the recov-
                  erable data module. Perform the following:
                  1      Verify transfer cable connections between data transfer unit and recoverable data
                         module.
                  2      If LED remains illuminated, replace data transfer unit. (Refer to 31-30)
                  3      If LED remains illuminated, replace recoverable data module. (Refer to 31-30)
                  4      If LED still remains illuminated, contact Cirrus Design for disposition.
             (f)  Install glove box trim. (Refer to 25-10)
             (g) Set BAT 1 switch to OFF position.
       (2)   Operational Test - Aircraft Data Logger System - Serials 2016 & subs w/ Perspective Avionics
             (a) Set BAT 1 switch to ON position.
             (b) Open center armrest console and remove glove box trim to access diagnostic LED. (Refer
                  to 25-10)
             (c)  Verify diagnostic LED indicates normal operation with several 0.03 flashes once per sec-
                  ond. If diagnostic LED does not indicate normal operation, refer to the following trouble-
                  shooting table.

                     Note:         During system power-up sequence, the diagnostic LED will briefly cycle
                                   through conditions 1, 3, and 4 before reaching final condition 5.
