PURPOSE:To read information generated at a storage section, and to attain announcement of call by constantly applying a drive power supply to a storage section storing generation information of a call announcement and a control circuit of call notice at all times, and providing a power supply supplying a drive power selectively to a radio circuit and a demodulation circuit receiving the selective call signal. CONSTITUTION:The power supply device 32 supplies a drive power to an electronic member such as the radio circuit 22 and the decoding circuit 23 via a power supply switch circuit 34. The drive power is always supplied to the constituting electronic member such as a ring tone control circuit 26, a storage section 29, a code collation circuit 24, a reset switch detection circuit 31 and a power supply switch circuit 34 comprising a device, e.g., a transistor switch detecting the interruption of the power switch 22 by a prescribed operation. When ring tone information is stored in the storage section 29, a reset switch 30 is not operated but the power switch 33 is turned off, then a ring tone is generated for a prescribed time T only and the called party grasps the generation of a call surely. |
