Reconnaissance and Surveillance Leader Course AN/PRC-104 MAINTENANCE KEEP CLEAN AND DRY KEEP ACCOUNTABILITY USE SOFT CLOTH OR BRUSH (DAMP) THEN DRY CLEAN AUDIO CONNECTORS WITH PENCIL ERASER DRY INTERIOR OF BATTERY BOX TO PREVENT CORROSION

Reconnaissance and Surveillance Leader Course AN/PRC-104 TROUBLESHOOTING SQUEALING IN HANDSET OR LOSS OF AUDIO: - CLEAN AUDIO CONNECTORS (RT AND HANDSET) WITH PENCIL ERASER - DRY AUDIO CONNECTORS IF WET - REPLACE HANDSET - CHECK BATTERIES

Reconnaissance and Surveillance Leader Course AN/PRC-104 TROUBLESHOOTING (CONT) RT WILL NOT TUNE: - CHECK COAX FOR CUTS OR FRAYS - CHECK ANTENNA ELEMENTS FOR CUTS OR FRAYS - ENSURE ANTENNA IS NOT SHORTED TO GROUND (TREES, BRUSH, GROUND, ETC) - ENSURE ANTENNA IS CUT TO PROPER LENGTH - CHECK CONNECTIONS

Reconnaissance and Surveillance Leader Course AN/PRC-104 TROUBLESHOOTING (CONT) HIGH VSWR INDICATOR: - ENSURE ANTENNA IS NOT GROUNDED OR DAMAGED - ENSURE ANT SEL SWITCH IS SET PROPERLY (50 OHM OVERRIDE WILL CAUSE HIGH VSWR) - ENSURE ANTENNA IS CUT TO PROPER LENGTH - CHECK ANTENNA CONNECTIONS
