Casio CZ/ VZ/ FZ - Pro Series

Hi All.  Sold my CZ1000 many years ago and finally got a HT-700.  It
does not have a RAM cartridge but I was under the impression that the
'Internal' (user writable) locations would store the patterns/patches
IF you kept batteries in it.  Trying this tonight and its works for a
minute but any longer and the stuff if lost.

So, should the internal memory hold stuff after turning off providing
you have batteries?

Thanks for any replies.
