location and time you use this product.
GPS is a system for determining geographic location by triangulating radio signals from GPS
satellites. Avoid using the camera in places where radio signals are blocked or reflected,
such as a shadowy place surrounded by buildings or trees, etc. Use the camera in open sky
environments.
You may not be able to record location information at locations or in situations where radio
signals from the GPS satellites do not reach the product as follows.
In tunnels, indoors or under the shade of buildings.
Between tall buildings or at narrow streets surrounded by buildings.
In underground locations, locations surrounded by dense trees, under an elevated bridge, or in
locations where magnetic fields are generated, such as near high voltage cables.
Near devices that generate radio signals of the same frequency band as the camera: near 1.5 GHz
band mobile telephones, etc.
If you upload and share the images which are recorded with the setting [GPS On/Off] is [On],
the record location may be exposed on the internet even if you do not intend to do so. If you
do not want to record location information, select [Off] for [GPS On/Off].
On triangulating errors
If you move to another location right after turning on the camera, it may take a longer time for
the product to start triangulating, compared to when you stay in the same place.
Error caused by the position of GPS satellites
The product automatically triangulates your current location when the product receives radio
signals from 3 or more GPS satellites. The triangulating error allowed by the GPS satellites is
about 10 m (32.81 feet). Depending on the environment of the location, the triangulating
error can be greater. In this case, your actual location may not match the location on the
map based on the GPS information. Meanwhile, the GPS satellites are controlled by the
United States Department of Defense, and the degree of accuracy may be changed
intentionally.
Error during the triangulating process
The camera acquires location information periodically. There is a slight time difference
between when the location information is acquired and when the location information is
recorded on an image, therefore, the actual recording location may not match exactly the
location on the map based on the GPS information.
On the restriction of use of GPS on an airplane
During take off and landing of an airplane, set [Airplane Mode] to [On].
If you do not want to record location information, set [GPS On/Off] to [Off].
