Getting power back into your Leitner base
If you plug your Leitner headset into a wall outlet or power strip, you should be seeing lights on the base. If you aren't, there is probably something wrong with the power somewhere down the line.

Troubleshooting methods
- Unplug then re-plug the power from the back of the Leitner base
- Move the power into a different power outlet. If plugged into a power strip, move to another port on the strip, and if that doesn't work, try plugging directly into the wall
And that's about it for troubleshooting. If those methods don't get your lights back, you will need a new power adapter.
