Wireless communication device and operating system for human-powered vehicle

An operating system for a human-powered vehicle, comprising:

• a wireless communication device including;
• a wireless communicator configured to wirelessly communicate with an additional wireless communicator, the wireless communicator having
• a first mode in which the wireless communicator operates under a first power consumption, and
• a second mode in which the wireless communicator operates under a second power consumption which is lower than the first power consumption;
• and
• a controller configured to detect a change in a state of at least one switch, the controller being configured to set the wireless communicator with the first mode if the controller detects the change in the state of the at least one switch as the wireless communicator is in the second mode,
• the controller being different from the wireless communicator,
• the wireless communicator being configured to wirelessly receive a shift control signal to change a shift position of a shift changing device from the additional wireless communicator of an operating device,
• the at least one switch attached to a brake caliper which is provided separately from the wireless communication device and the operating device,
• the at least one switch including a switch circuit disposed within a caliper body of the brake caliper, and
• the switch circuit is disposed within a bore extending through an outer wall of the caliper body of the brake caliper.
