PURPOSE:To utilize an incoming call tone for the alarm tone of time. CONSTITUTION:When an incoming call detection circuit 2 detects an incoming call signal via a radio transmitter/receiver 1, an incoming call tone generation control circuit 4 generates the incoming call tone by controlling an incoming call tone generation circuit 3, and sounds it from a speaker 7, and when an off-hook signal (a) from a transmission/reception circuit 6 is detected, the generation of the incoming call tone is stopped. Also, when a time arrives at the one set on a timer 5 in advance and the incoming call tone generation control circuit 4 receives a control signal from the timer 5, the incoming call tone is generated similarly, and when the off-hook signal (a) is detected, the generation of the incoming call tone is stopped. |
