## Discrepancy

THE ELT TRANSMITTER WOULD ACTIVATE ITSELF WHILE THE AIRCRAFT WAS STATIC IN THE HANGAR.  THE UNIT WOULD ALSO SELF ACTIVATE WHILE SITTING ON THE BENCH.  THE ON/OFF SWITCH ON THE ELT COULD BE TURNED ON THEN BACK TO OFF AND THE ELT WOULD REACTIVATE WITHIN A FEW MINUTES.  THERE WERE NO VISUAL DISCREPANCIES NOTED ON THE ELT UNIT.  REPLACED ELT UNIT WITH A NEW ONE.  CONTACTED REGISTERED OWNER FOR ADDITIONAL INFORMATION.  DISCOVERED THAT THE EMERGENCY LOCATOR TRANSMITTER IS ONE OF THE NEW TYPE: C4062AF (AUTOMATIC FIXED) WHICH WAS PART OF THE ORIGINAL FACTORY INSTALLATION.  INDIVIDUAL STATED THAT THEY DID NOT TRY REPLACING THE BATTERIES, BUT OPTED FOR A COMPLETE REPLACEMENT OF THE UNIT.
