I'd was using the Fuji Cam Remote app to test image download to iPhone over bluetooth/wifi, and had disconnected, and turned off bluetooth on the camera.
Now, the "location data download status" indicator (a globe with a pin it in, if you look hard enough) is constantly blinking red whilst shooting. It's labelled 52 on page 13 on the manual.
I've power-cycled the camera and, in Setup, Connection, Bluetooth (which is off, though I did try turning it back on briefly), I've changed Smartphone sync setting from Location and time to just Time, then to Off, but it's still flashing.
Any ideas?
