NOTE:
  • Freeze frame data stored at the time of trouble occurrence is shown on the display.
  • Each time a trouble occurs, the latest information is stored in the freeze frame data in memory.
  • One freeze frame data is stored.
  • For detailed operation procedures, refer to "Application help".
