<p>PURPOSE:To simplify the circuit constitution and to improve the operability of a repeater by replacing the detection value of a reception electric field strength in a portable microwave repeater into a correction value stored in advance and displaying the result. CONSTITUTION:A reception electric field strength detected by an electric field strength detector 101 composed of a diode or the like is read by a read means 102. Then a correction value selecting means 104 selects a correction value corresponding to the detected reception electric field strength among correction group stored by a correction value storage means 103. Then the correction value is displayed on a display device 106 by a correction value display means 105. Thus, the design of the electric field strength detection circuit is facilitated and the display characteristic of the optional reception electric field strength is obtained and the operability of the repeater is enhanced.</p> |
