を指示する。The lowest voltage at which the battery 1 can operate is preset in the voltage detection circuit 3. Voltage detection circuit 3 detects the voltage of battery 1, which is the main power source, and compares it with a set voltage, and transmits this information to CPU 12 when the voltage of battery 1 becomes lower than the set value. Based on this voltage information, the CPU 12
Perform the following operations according to the program in l0. CPU1
2 rejects the input from the user using the key 4, and transfers the text data and status information stored in the memory 11, which is the first storage device, to the external storage device 8, which is the second storage device. . Then, in order to notify the user through the display 7 that the memory backup operation has ended, a request for battery update is required, and further key input is to be rejected.
The CPU 12 instructs the display controller 6 to display character information.
