Acquiring GPS Signals
Signal acquisition takes about 30 – 60 seconds under favorable
conditions after you turn the camera on.
After initial signal acquisition, signals can be reacquired soon after the
camera is turned on again (under favorable conditions, and when the
camera has been off for less than approx. 30 minutes).
Places with Poor GPS Coverage
Location information may not be recorded, or inaccurate information may be
recorded where GPS signal coverage is poor, such as in the following
places.
Indoors, underground, in tunnels or forests, near buildings or in valleys
Near high-voltage power lines or mobile phones operating on the
1.5 GHz band
When traveling through different environments
Even in other places, GPS satellite movement may interfere with
geotagging and cause missing or inaccurate location information. The
information may also indicate that the camera has been used in a
different location, even if you were shooting at the same place.
Appended Information
If shooting is performed immediately after turning on the camera's power
switch (or resuming use after auto power off) when the receiver is
attached to the camera, images may not be geotagged. Similarly,
directions may not be recorded correctly. To avoid this, wait a moment
before shooting.
