  • GPS synchronisation of precise time
  • Allocation of current position to individual records according to GPS
  • On-line back-up of records to back-up disc
  • Recorder diagnostics including status LEDs
  • Interface for external diagnostic indicators connecting
  • History records of operational statuses of the recorder for the whole period of use
  • Minimum recording capacity of 100 operating hours (higher capacity available upon customer request)
