It is composed of an indicator light.

FIG. 3 is a block diagram showing an example of a conventional wireless selective calling receiver with a display function.

When the receiving antenna 1 receives a carrier wave modulated with the individual selective calling number and display information, the radio section 2 inputs and demodulates the carrier wave and outputs it as a demodulated signal. Waveform shaping circuit 3
inputs the demodulated signal, converts it into a digital signal, and outputs it as a decoded signal a. The storage unit 6 stores a self-calling number C in advance. The decoder 8 controls the storage unit 6 to read out the self-calling number C, compares it with the individually selected calling number in a of the decoded signal input from the waveform shaping circuit 3, and if they match, display information following the self-calling number d. The display device 9 which separately outputs the display information e and the flicker signal f receives the display information e and displays characters, numbers, symbols, etc. The flicker indicator lamp 12 performs a flicker operation based on the flicker signal f.

The light amount detector 4 converts the external light amount into a light amount signal and outputs it. The illumination control section 11 inputs the light amount signal b, and if a predetermined amount of light is obtained, controls the display illumination section 10 to turn off the illumination. If the predetermined amount of light cannot be obtained, the display illumination section 10 is controlled to turn on the illumination. That is, if the outside is sufficiently bright, the display lighting unit 10 is turned off, and if the outside is dark, the display lighting unit 10 is turned on so that the display 9 can be seen. The clear switch 5 is provided to put the receiving state again. When turned on, the clear switch 5 outputs a clear signal g, and the decoder 18 detects the clear signal g and returns to the receiving state again.

By the way, it is necessary to check the reception operation of a radio selective call receiver with a display function at the time of manufacturing or maintenance in order to evaluate its properties. For wireless selective calling receivers with display function, -
Once the individually selected calling number and display information that match the self-calling number are received, they are retained internally, so in order to confirm reception again, it is necessary to press the clear switch to erase the received information.

2 generates an encoded signal. The signal generator 23 is controlled by the computer 21, and the generated signal frequency, generated electric field strength, etc. are set. The carrier wave generated by the signal generator 23 is modulated by the encoded signal generated by the encoder 22 and sent to the transmitting antenna 24 . The modulated carrier wave is transmitted as a radio wave by a transmitting antenna 24, and a radio selective call receiver with display function (hereinafter referred to as a receiver) 25 receives the radio wave. The receiver 25 that has received the radio wave performs a flickering operation of a flicker indicator lamp and displays the received display information as a response operation. The computer 21 uses the operation detection unit 26 to recognize the operation state of the receiver 25 from the flicker indicator light and indicator of the receiver 25. If the receiver 25 is performing a receiving operation, the computer 21 controls the clear switch pressing mechanism, and the receiver 2
5 becomes receivable again. These steps are repeated to confirm the reception operation of the receiver.

A receiving antenna 1 receives a carrier wave modulated with an individual selective calling number and subsequent display information, and a radio section 2 demodulates the carrier wave and outputs a demodulated signal. The waveform shaping circuit 3 converts this demodulated signal into a decoded signal a, which is a digital signal, and outputs it. A self-calling number C is stored in the storage unit 6 in advance, and is read out under the control of the decoder 8. The decoder 8 compares this self-calling number C with the individually selected calling number in the decoded signal a, and if they match, separately outputs the display information e following the self-calling number and the flicker signal f.

The illumination control section 11 receives the light amount signal, and if a predetermined amount of light is obtained, controls the display illumination section 10 to turn off the illumination. If the predetermined amount of light cannot be obtained, the display illumination section 10 is controlled to turn on the illumination. That is, if the outside is sufficiently bright, the display illumination section 10 is turned off, and if the outside is dark, the display illumination section 10 is turned on so that the display 9 can be seen.
