What was found
WHEN REMOVED FROM BOX, THE AK-450 ELT DID NOT PERFORM ON THE BENCH AS REQUIRED. THIS IS THE 2ND ELT RECEIVED OF THE SAME MODEL WITH PROBLEMS. THE AUDIBLE SWEEP WOULD STICK AND ONLY A SINGLE TONE WOULD BE HEARD. WHEN TURNED ON, THE ELT WOULD SOMETIMES NOT OPERATE. WIGGLING THE SWITCH AND/OR ANTENNA CONNECTION WOULD HAVE INCONSISTENT RESULTS IN GETTING THE ELT TO OPERATE. ELT WAS NOT INSTALLED IN ACFT DUE TO THESE PROBLEMS.
