When the camera establishes
communication with a GPS device, a k icon
will be displayed in the top control panel.
Photo information for pictures taken while
the k icon is displayed will include an
additional page (pg. 238) recording the current latitude, longitude,
altitude, Coordinated Universal Time (UTC), and heading. If no
data are received from the GPS unit for two seconds, the k icon
will clear from the display and the camera will stop recording GPS
information.

GPS Data
GPS data are only recorded when the k icon is
displayed. Confirm that the k icon is displayed
in the top control panel before shooting. A
flashing k icon indicates that the GPS device is
searching for a signal; pictures taken while the k
icon is flashing will not include GPS data.
