Avantis ContentCache default administrator login
We have just discovered an Avantis ContentCache 310 sitting unused in a storeroom. We have plugged it in and it seems to be working. Our problem is that we don't have any record of the teacher or administrator login details in order to do any further configuration or management. I'm hoping that the administrator has been left as a default - does anyone know what this might be or how I can reset the login credentials to a known setup?
