If the control box freezes and doesn't respond to any keypresses, there could be a couple of things to try.

First, disconnect the battery and reconnect it to get the control box responding again.

Next, check the software version. If this version is v1.31, there's  known issue that causes some problems with other devices on the board. Send the board back to us and we'll upgrade the software for you.

If the software is a different version, the board may be faulty. Send the board back to us and we'll take a look at it.

If this doesn't fix the issue please:
