Portable device and remote control system

摘要

A portable device (12) that remotely controls a remote control subject (11) by receiving a response request signal (Srq) transmitted through wireless communication from a control unit (13) of the remote control subject (11) and returning a response signal (Srp) for the response request signal (Srq) to the control unit (13). The portable device is configured to set a response sensitivity (Vh) based on response sensitivity information (Srec) suitable for the remote control subject (11) transmitted through wireless communication from the control unit (13) separately from the response request signal (Srq).
