PURPOSE:To recognize the quality of received data immediately for the user of radio call communication by deciding a reception state based on an error rate or the like concerning the respective signal parts of data constitution in a prescribed encoded format transmitted by radio and displaying a mark showing high quality when they are decided as high-quality data. CONSTITUTION:A CPU 6 confirms the detecting signals of preamble and word synchronizing signals fetched from a word synchronizing signal detecting part 4b and confirms the address data of message data fetched from an address detecting part 4e. Next, it is decided whether the error rate concerning the error correction data of address data fetched from an error correcting and detecting part 4f exceeds a prescribed reference value or not and when the error rate is lower than the reference value, the state of receiving high-quality receiving data is decided. When the satisfactory reception state is decided, a display showing the possession of high-quality received data is displayed on a display part 7. |
