Abstract:
1. A portable telephone radio set with an interference detection function to which a terminal equipment can be externally connected to effect data communication therewith, comprising: a warning section for warning radio wave interference by audio or visual signals; and a control circuit section for selecting and switching among a group of channels available for communication, said control circuit detecting interference of radio waves in a channel selected for communication and controlling said warning section; said control circuit section reporting, when said control circuit section detects a radio wave interference fault, a type of the fault to said warning section so that said warning section may give a warning of radio wave interference in a form based on at least one of visibility and audibility, but if a cause of the radio wave interference disappears as a result of establishment or switching of the channel, then said control circuit section controlling the warning section to erase the warning of radio wave interference.
