The Super Bass Station comes preloaded with 200 sounds. The first 50
programs ("A" bank 000 to 049) cannot be overwritten as these are
stored in Read Only Memory. The remaining 150 memory locations ("A"
bank 050 - 099 and "B" bank 100 - 199) are RAM locations. If necessary
the factory sounds stored in the RAM locations can be recalled by
holding the save & write buttons simultaneously while applying
power to the Super Bass Station. The Super Bass Station stores user
sounds in a memory device which does not require back up power,
therefore the Super Bass Station does not have a back up battery.
