PURPOSE:To surely allow the circuit to show a battery life by allowing the circuit to drive a time counting circuit with the use of another battery to perform an indication different from the usual indication or perform specific characters and figure indications in the case where the voltage of the battery lowers or operation is stopped by removal thereof. CONSTITUTION:When a time display key 5 is pushed at the time when the power source voltage 10 of a battery 1 is in a range of ordinary operation of a time counting circuit 3, an indication control circuit 4 is allowed to read time data 12 to perform time indications at the time of the ordinary operation on a display 9. When the power source voltage 10 is lower than that of the ordinary operation, time indications and an indication of 'Exchange the battery' are performed on the display. When the time display key 5 is pushed at the time when the power source voltage 10 lowers down to a range of a malfunction, other indications are performed. |
