The master station device comprises a first down repeater for receiving a signal from the base station device to amplify and send it to the slave station device, a first up repeater for receiving a signal from the slave station device and amplify and send it to the base station device, and a first control unit for controlling the master station device. The slave station device comprises a second down repeater for receiving a signal from the master station device to amplify and send it to the mobile station device, a second up repeater for receiving a signal from the mobile station device and amplify and send it to the master station device, and a second control unit for controlling the slave station device. The repeater amplifier apparatus further includes a slave station operation program changing means for changing an operation program of the slave station device through the control unit of the master station device when the master and slave station devices are in normal operation.
