How do I manually start and stop logging on my DL1 PRO?
When the DL1 PRO is not logging, the “logging” LED will not be illuminated. Make sure that the status LED is flashing, this indicates that the unit has a valid memory card inserted and is ready to start logging. If the LED is not lit, check that the memory card is not full and is correctly formatted.
Press the Start/Stop Logging button. The Logging LED will illuminate and logging will start. To stop the logging press the button again.
