Hi I'm trying to find a user manual for a portable blu-ray disc player that I have just bought second hand. unfortunately the person I bought it off no longer has this. the model number on the bottom is BPBS23108. It does work but I understand it has an internal lithium battery which at some point will probable need renewing and I also want to know other information like downloading and installing the latest software etc, but cannot do this without some sort of information. Any help would be greatly appreciated, especially a PDF of said manual or guidance on how to obtain one. I have contacted Argos, who apparently now own Bush but they have no information at all and suggested this site as a possible source.
