c. NO BATTERY
If the user forgets to replace the battery and the battery voltage
falls below a certain level, or if a power failure occurs with no
batteries installed, the memory contents cannot be retained. The
CPU judges it as no battery and performs the master reset. In this
case, all the settings and registrations are cleared. If, however, the
power is continuously supplied to the AC cord, the memory
contents are retained.
