## Discrepancy

IAH TO BTR - AFTER TAKEOFF CREW RECEIVED AN"OVBD COOL" EICAS MESSAGE.  THE CREW NOTICED THAT THE CABIN PRESSURE WAS ABNORMAL AND PROCEEDED TO THE UNPRESSURIZED FLIGHT PROCEDURE.  WITH THE AIRCRAFT AT 4,000FT AND THE CABIN ALTITUDE AT 2,300FT THE "EMER DEPRESS SWITCH" WAS PRESSED AND THE CABIN PRESSURE EQUALIZED.  THE FLIGHT RETURNED TO FIELD AND LANDED WITHOUT INCIDENT.  MAINTENANCE INSPECTED AND FOUND THE SERVICE DOOR HANDLE NOT PROPERLY STOWED.  AFTER CYCLING THE DOORS THE PRESSURE SYSTEM OPERATED NORMALLY.
