        1. A MAINTENANCE PROBLEM BEING ENCOUNTERED DURING PROJECT DESERT
        SHIELD INDICATES THAT MANY M43AI DETECTORS (A COMPONENT OF THE MSAI)
        ARE SOUNDING AN ALARM DUE TO HEAVY CONCENTRATIONS OF SAND AND ENGINE
        EXHAUST. ETC. THESE ALARMS CANNOT BE RESET WHICH RESULTS IN THEM
        BEING TURNED IN FOR HIGHER LEVEL MAINTENANCE.
        2. CHANGE 3 TO TM 3-6665-329-12&P (DUE OUT IN FIRST QUARTER FY91)
        WILL PROVIDE DETAILED INSTRUCTIONS ON OPERATORS PURGING OF THE M43AI.

        FILTER ON AIR INLET PORT.
             D. TURN DETECTOR ON AND ADJUST VOLUME TO LOW LEVEL.
             E. LET THE DETECTOR RUN FOR A FEW MINUTES. IF NEEDLE DOES NOT
