Boss BR900CD memory card problem

I recently got one of these. Wanted to simplify things and get away from computers, as I already spend too much time on them as it is. I have no previous experience of this device or others in the same product line.

Anyway, it didn’t come with a power supply, so I ordered one. In the meantime I thought I would power it with batteries, while I try to learn the ins and outs of the thing.

However once I inserted the Flash card, it is stuck in an endless loop where it alternates between the title screen and a prompt that says, keep power on, testing memory card. I have allowed it to go on like this for about 10 minutes, but it doesn’t seem to resolve itself.

It seems the cd-r drive requires a wall power aupply to work, I wonder if this could be a similar problem that will be solved when I get the power supply? Or is the card itself faulty?

Any advice would be greatly appreciated! Thank you for reading.
