## Discrepancy

THE R3 DOOR SLIDE PRESSURE INDICATION ON CIDS PANEL. MAINTENANCE INSPECTED THE OVERWING SLIDE INFLATION BOTTLE IAW AMM 25-62-49,  FOUND PRESSURE INDICATION GAUGE IN GREEN BUT JUST ABOUT AT THE CHECK BOTTLE PRESSURE WARNING FOR CIDS ON GAUGE. REMOVED AND REPLACED THE DECODER/ENCODER B UNIT IAW AMM 23-73-49.  OPS CHECKED GOOD.
