In case you have already collected data with the OLI and you don't want to download it, you can delete it manually by following these steps:

1. Turn on the OLI. The orange solid light indicates that the OLI has data recorded.

2. To erase data from the OLI, press the "OLIVER" button 3 times in a row once the orange light has appeared.

3. The orange light will start to flash indicating that data is being erased correctly. It will take a few seconds to erase all data.

4. Once the deletion process has finished, a green solid light will show up.

5. Turn the OLI off by holding the "OLIVER" button for 3 seconds.
