    1. Send the full data dump from the GUI of the data showing the error. Keep the target distance fixed and also provide the actual distance so error can be seen. Instructions to do the data export are in the EVM users guide, but you just need to check the box circled below, select the output location, click start capture, and then click stop capture after all required data is captured to show the error.                                                                  
    2. Include a picture of the EVM board and the test setup
    3. Include the board ID of the EVM. EVM board ID is on the sticker on the board with the QR code and circled in red below.
    4. Optional: Measure and include the residue crosstalk. To measure crosstalk place 3-4 layers of black electrical tape over the photodiode as shown below in the blue circle. Make sure that the tape is pressed firmly down to completely block light from entering the photodiode. With the photodiode masked the crosstalk is the reported amplitude in the GUI when longRange mode.is selected in the mode select.
