PURPOSE:To exclude an artificial error in judgement of an evaluation test for a message display function of the display type radio calling receiver and to improve the test job efficiency. CONSTITUTION:Message display data received and demodulated in succession to a call signal by the display type radio calling receiver are stored in a display data memory 8 as codes without any conversion, and when a call end signal is outputted from a call end discriminator 9, the display data are read from the memory 8, and an optical signal subject to optical modulation by the display data is outputted from a calling use LED 6 via an AND circuit 10 and a NOR circuit 11. Thus, the optical signal outputted from the LED 6 of the display type radio calling receiver is converted into an electric signal, demodulated and collated with the sent display data to allow the electric evaluation test. |
