@Positioning will take time in environments where it is difficult to
receive the signals from the GPS satellites. For details, refer to
"Using the GPS function to record the location of a picture" (Owner's
Manual for advanced features).
@Even if GPS reception is good, it will take approx. 2 to 3 minutes
to successfully execute positioning under the following conditions;
when positioning is executed for the first time, or when positioning is
executed after the camera is turned off with the [GPS Setting] set to
[OFF] or [Airplane Mode] set to [ON], and then turned on again.
