## Discrepancy

FLIGHT 5640, IAH TO LIT.  WHILE CLIMBING THROUGH 23,000FT THE FLIGHT CREW RECEIVED A R REV UNLOCKED EICAS MESSAGE.  THE EMERGENCY ACTION ITEMS WERE RUN AND THE RELEVANT CHECKLISTS WERE COMPLETED.  THE REVERSER WAS THEN STOWED, BUT THE R REV UNLOCKED MESSAGE REMAINED ON EICAS.  THE AIRCRAFT RETURNED TO IAH AND LANDED WITHOUT INCIDENT.  MAINTENANCE COMPLIED WITH THE MEL PROCEDURES FOR THE REVERSER AND RELEASED THE AIRCRAFT TO SERVICE.
