Summary:PROBLEM TO BE SOLVED: To provide a mobile radio system that can flexibly comply with a communication condition in each country and can easily match a communication condition between a master unit and a slave unit at the site.SOLUTION: A mobile radio system has a main communication mode of performing transmission of speech or reception of speech, and an initial setting mode of matching, by radio communication, a condition to perform transmission or reception of speech between a master unit and a slave unit in the main communication mode. Frequency bands used for communication in the two modes are different from each other. By performing predetermined operation at the master unit or the slave unit, they can be shifted from the main communication mode to the initial setting mode any time.SELECTED DRAWING: Figure 1 【課題】各国における通信条件に柔軟に対応することが可能であり、かつ、現場において親機と子機との間の通信条件の整合を容易に行うことのできる携帯無線システムを提供すること。【解決手段】送話又は受話を行う本通信モードと、本通信モードにて親機及び子機の間で送受話を行うための条件を無線通信により整合させる初期設定モードとをそれぞれ備え、これら二つのモードでは通信に用いる周波数帯が互いに異なり、親機や子機において予め定められた操作を行うことにより、いつでも本通信モードから初期設定モードへと移行できるようにした携帯無線システムを用いる。【選択図】図１
