## Discrepancy

MADE AN UNPLANNED LAS STOP DUE TO PARTIAL LOSS OF CABIN PRESSURE.  CABIN STARTED TO CLIMB, SWITCHED TO MANUAL.  WHILE CONTROLLING IN MANUAL AUTO STARTED TO CONTROL THE OUTFLOW VALVE.  *S/D*  REMOVED AND RERACKED THE CABIN PRESSURE CONTROLLER AND THE SYSTEM OPERATIONALLY CHECKED GOOD.
