Hello,
I have a BS 9000 that loses the settings I make using the remote control after I turn off the power. So I press the red button.
BS 9000 actually works without any problems and can also set all parameters unless I turn it off completely. What have I already checked? There is a 3V 3.2V battery on the CPU board. The SRAM on the mainboard is also at 3.2 volts and the crystal oscillates. I have already replaced the MK41T56. According to the schematic, I don’t see any additional memory. Does anyone have an idea where else I can look?
Thanks
