PURPOSE:To attain labor saving in a code registering work on each repeater and to surely guarantee a normal operating state by providing a means to perform code registration on the repeater by radio transmission from a transmitter and to set a transmission level or a reception level in the code registration less than a level in an operation. CONSTITUTION:The means 39 is provided to perform the code registration on the repeater 3 by the radio transmission from the transmitter 2 and to set the transmission level or the reception level in the code registration less than the level in the operation. Since the code registration on the repeater 3 is performed by the radio transmission from the transmitter 2, a work to register the same kind of code on the repeater 3 can be omitted by setting the various kinds of codes such as an equipment code or an addition code on the repeater 3. And when the code registration is performed by setting the transmission level or the reception level in the code registration less than the level in the operation, a relay operation can be surely guaranteed. |
