AKAI EWI 5000 r) Error resurrection mystery

After the EWI drained all the battery and recharging I got a strange error code that was not explained in the manual also not on the internet. So I tried everything...

Don't know if it is called a r) or t) error or maybe r reversed C error?

Sometimes I call it a 5000s it is off course a 5000. I removed the letters from the side some time ago and I am already mixing up the name with the 4000s. Sorry
