Abstract

PURPOSE:To enable to know accurate communication time and to enable to monitor for the communication time on the way of communication with display. CONSTITUTION:The system is provided with the signal generating circuit 1 to generate the reference time signal, and the output of the circufit 1 is controlled with the AND circuit 2 with the output of the OR circuit 6. The output of the circuit 2 is counted with the count circfuit 3 in hour, minute and second unit, and the condition of count for the circuit 3 is displayed with the display circuit 4 in hour, minute and second unit. The switch 5 makes the condition of the circuit 3 as initial condition. The switch 8 opens the contact when th opposed subscriber responds in case of mobile station call, and the switch 9 interlocked with the hook switch is opened for the contact when the hook switch is in off-state. Thus, the stop watch display function is added to the radiotelephony, starting the timer at call when the opposed subscriber responds. Further, the timer is started at incoming call when the hook switch is off and the timer is stopped at the end of call, allowing to tell the communication time accurately.
