Abstract

PURPOSE:To avoid the malfunction of gauges, by carrying out the radio communication between a mobile station carried with an operator and an antenna system installed at the working site by a modulation system having a constant amplitude of carrier wave and then setting the electric power of transmission at a certain level or less. CONSTITUTION:The simultaneous calling device is formed by the mobile stations 1-5 carried with the operators, the fixed station 6 installed apart the working site, and the antenna system 7 that performs a radio repeating between the stations 1-5 and the station 6. In this case, a modulation system having a constant amplitude of carrier wave is used for the radio communication, and furthermore the electric power of transmission is set at 100mW or less.
