A mobile receiver unit which has a function for providing information of an electric field intensity and which is used in a mobile radio telephone system includes a level detector (1) for outputting a level detection signal corresponding to an electric field intensity, and an information producing unit (3, 4) for signalling to a user information of a geographic gradient of the electric field intensity on the basis of an output signal from the level detector (1). The information producing unit includes a display (4) and/or an acoustic device for indicating a direction of a higher electric field intensity. |
