The first indication that your soundboard is working properly is after installing charged batteries you should hear the "boot up" sound. If that's not happening then there could be an issue with the soundboard itself.
Have you tried hooking your board up to your computer? Have you had any trouble connecting to your saber or had any faults uploading new sounds to your saber?
Or...if you've never done the above, then I'd suspect your board could be faulty and you should proceed by contacting US by email explaining your situation in detail.
I have the LITE obsidian sound, and yes, the boot up sounds saying 'obsidian'.
I've already sent an email
but as they're too bussy, they might respond in 3 or 6 days
Anyway, thank you for your support, i knew i could get some help on the forums!
