The power sometimes turns on unintentionally.

Depending on the specifications of a nearby computer, smartphone, or other Bluetooth device, the camera may turn on.
Even when the camera is unintentionally turned on, it will not be operated by or receiving images from a device for which it has not carried out a connection setup in advance.   

• If the Auto power off function is available, the power is automatically turned off.
• To prevent the camera from being unintentionally turned on when not using it, turn the Bluetooth setting or Bluetooth remote controller power setting of the camera to OFF or turn its Airplane mode to ON.
