Title: Battery voltage display apparatus for wireless communication system

Abstract: When bidirectional wireless communication has been established between a controller section, a system main section transmits an instruction to the controller section to detect a remaining power of a battery. The system main section designates a timing to detect the remaining power and displays the result. The system main section can determine the occurrence of an error when no response is received, resulting in confirmation that the battery has run out in the controller section.
