What sound board do you have? They're is more then one. I'm guessing V3 maybe since it is rechargeable? But it could also be a V4 which has a mute setting also. Or even a Diamond with the volume turned down?
You are not seeing too expect or to work correct or off the box. Do you own any other Ultrasabers? Because learning to use one the first time may not be easy if you don't know everything about it.
Unfortunately getting ahold of customer service is the hardest part, but once you do they should be able to help you.
The only way I know that works for sure is to email
