Battery replacement for universal model QCPU
Are contents of the program memory, the standard RAM, and latch devices erased when the battery of universal model QCPU is replaced?

Answer
The contents of the standard RAM and latch devices are not erased if the battery replacement is completed within three minutes, which is the backup power time.
Since the program memory is a flash ROM, the data is not erased even if the battery runs down.
