NFC Function Cautions
This camera cannot be connected to other NFC-enabled cameras or

printers using the NFC function.
A connection cannot be established using the NFC function while

shooting with the camera, when there is no card, when the LCD monitor
is closed with the screen facing inward, or while the camera is connected
to another device with an interface cable.
To connect the camera to a smartphone using the NFC function, 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.
