NFC Function Cautions
This camera cannot be connected to other NFC-enabled devices, such

as printers, using the NFC function.
A connection cannot be established using the NFC function while

shooting with the camera, when there is no card, or while the camera is
connected to another device with an interface cable.
To connect the camera to an NFC-enabled smartphone, the

smartphone's Wi-Fi and NFC functions must be enabled.
A connection can be established even when the camera's power is in the
auto power off state. However, if a connection cannot be established, cancel
auto power off, then establish a connection.
