The reported event of radio frequency (rf) lockout and failure to interrogate was not confirmed.Data analysis of the device image suggested rf telemetry lockout had occurred in the field due to excessive rf usage in a short period of time.This lockout feature disables the high-power telemetry to prevent battery drain due to unintended excessive usage.As received, the lockout period had expired.Device showed normal characteristics and able to be interrogated successfully on various merlin programmers.Rf telemetry could be enabled and disabled with no issue.The device was received in normal range of operation.The device was then programmed to nominal settings for the remainder of the analysis.The results of all electrical test performed, including thermal and mechanical stress testing indicate no anomalies.Longevity assessment was performed, and device is considered normal battery depletion.
