PURPOSE:To confirm accumulative call time by counting the call time from the start of a call to the end of the call, updating the accumulative call time according to the call time with the end of the call and displaying the suitable accumulative call time at a display part according to a request. CONSTITUTION:When the call is started, a processor 11a-1 immediately clears the contents [call time (t)] of a memory part 11a-2 to be zero and counts up the call time (t) by one each time one second elapses. When an F key and a 5 key for call time display are simultaneously displayed, the processor 11a-1 displays the call time (t) stored in the memory part 11a-2. Therefore, at the time of the call, the current call time is displayed at real time and after the call, the latest call time is displayed. |
