てから発音体７を吹鳴させる。Next, the operation of the above configuration will be described. A radio signal composed of a modulated wave of an individually selected call signal received by the antenna 1 and an information signal following the demodulated signal is demodulated and decoded by the receiving section 2 and output to the decoder 6 after being waveform shaped as a digital pulse signal. The control unit 3 is for performing processing of an information signal, storage, determination of correctness and control of each unit. The input signal from the receiving unit 2 establishes synchronization and collates by the synchronization collating unit 6a,
Check for a match of whether your station is being called. When the own station is called, the received information is subsequently converted into 8-bit parallel data a and sent to the control unit 3. The control unit 3 decrypts the data by the decryption / determination unit 3b,
The error correction is performed, the data is stored in the memory 3a, the display data is sent to the conversion unit 4 via the decoding / determination unit 3b, and the presence or absence of an error and a message are displayed on the display device 5 such as an LCD. On the other hand, in the decoding / determination unit 3b, the frequency switching signal b and the ON / OFF signal c of the ringing sound are respectively generated by the pattern generation unit 6 depending on whether there is an error.
It outputs to b and the frequency divider 6c. The frequency divider 6c changes the frequency division ratio depending on the presence or absence of an error, and outputs signals of different frequencies to the gate 6d. The output of the pattern generator 6b is logically ANDed with the output of the frequency divider 6c by the gate circuit 6d and amplified by the amplifier 6e before the sounding body 7 is blown.

き、検査効率の向上に寄与するものである。As described above, according to the present invention, when a correct signal cannot be received due to a poor communication state when receiving a signal sent from a base station to an individual selective call receiver, a message to that effect is displayed on the display unit. Is displayed, and the sounding body emits a sound of a frequency different from the sound in the normal reception state to notify the user of abnormal reception. Therefore, both the eyes and the ears can know whether or not the received signal is normal. Moreover, at the manufacturing plant of the individual selective call receiver, when the automatic inspection is performed unattended in the inspection process, the individual selective call receiver is put in the shield case to prevent unwanted external radio waves from entering. Do,
At that time, by placing a microphone in the shield case and measuring the ringing frequency, it is possible to automatically inspect whether the individually selected call receiver responds correctly to both correct and incorrect signals, contributing to improved inspection efficiency. To do.
