Abstract
A terminal device is capable of communicating with a master wireless device. The terminal device includes a control circuit. The control circuit has operating modes including a normal mode for outputting startup information relating to startup of the terminal device, and a registration mode for outputting registration information relating to registration with the master wireless device. One of the operating mode of the control circuit shifts to the registration mode based on timing of plural startups of the terminal device. The terminal device can shift to the registration mode using the same operation and mechanism as operating in the normal mode.
