This is a FOSTEX VM08 digital mixer. It was working fine before, but the internal battery seems to have died, and the settings are sometimes reset. Also, when I turn it on, it starts up, but then it immediately restarts repeatedly. Therefore, I cannot confirm the operation of other functions. I don't know if it's due to insufficient capacity from the deterioration of the AC adapter, a power supply failure in the main unit, or some other cause. I hope someone who can repair it or use it for parts will take it. The contents include the main unit, adapter, and instruction manual.
