問題を抱えている。l: Problems to be Solved by the Invention] This "B map relay system" enables wireless communication between slave stations within the same zone, which was not possible with the "A map relay system". However, on the other hand, it is advantageous that the radio repeater does not require the intervention of 2 and 4, but on the other hand, there are a total of 4 transmissions and
A receiver is required, so when you want to temporarily install a wireless repeater, it is necessary to gather two slave stations together and wire them between them, which is not the case with "Figure A relay". I have a problem.
また、中継動作中は、４つの送・受信部の半数しか稼働
せず、装置が無駄に使用されるというのも欠点である。Another drawback is that only half of the four transmitting/receiving sections are in operation during relay operation, resulting in wasted use of the device.

Which transmitter/receiver of the repeater or slave station is the fault occurring?
It also includes problems such as difficult and time-consuming exploration and identification.
