Here are troubleshooting steps you can do on your own:

  •  Can you tell us the version of your board and if you can’t find it please take a picture for us.

  •  Do you have a way to test your 9V battery? Did you try it with a new one?

  • When you flex your arm can you hear that "whoosh" sound on the speaker?

  • To connect to a smartphone you need the Green cable(smartphone), be sure they have the right sides on the right devices(smartphone to smartphone)--(Spikerbox to Spikerbox).

  • After opening the SpikeRecorder and connecting the cable, clap your hands and tell us if you can see it on the screen!

  • Some phone cases can block the smartphone cable jack to go all the way in, be sure that is not the case.
