If your Plinth doesn't do this there may be a problem. Please try the following possible solutions before submitting a help request:
- Replace the batteries inside the plinth with a fresh set (don't mix old and new batteries)
- Make sure to press and release the power button whilst powering-on (don't hold-down the power button or else it'll power-off again after a few seconds)
If the steps above don't solve the problem then please submit a request here.
