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.
Claims40
A battery voltage display apparatus, for a wireless communication system, the battery voltage display apparatus including an input device, powered by a battery, having an input section for accepting entry of input and a transmission section for wirelessly transmitting the input, and a system main section having a receiving section for receiving transmission of the transmission section,
- wherein:
- the system main section includes:
