[98] How to use Others PrecautionsOn GPSAs the positions of GPS satellites vary constantly, it may take longer to determine thelocation or the receiver may not be able to determine the location at all, depending on thelocation and time you use the camera.GPS is a system that determines your position by receiving signals from satellites. Avoidusing the GPS feature on your camera in places where radio signals are blocked orreflected, such as a shadowy place surrounded by buildings or trees, etc. Use the camerain open sky environments.You may not be able to record location information at locations or in situations whereradio signals from the GPS satellites do not reach the camera as follows.In tunnels, indoors or under the shade of buildingsBetween tall buildings or at narrow streets surrounded by buildingsIn underground locations, locations surrounded by dense trees, under an elevated bridge, or inlocations 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 1.5GHz band mobile telephones, etc.If you take images with the GPS log set to [ON], and upload those images to the Internet,the shooting location may be available to third parties. To prevent this, set GPS log to[OFF] before shooting.[99] How to use Others PrecautionsOn GPS errorsIf you move to another location right after turning the camera on, it may take a longer timefor the camera to start triangulating, compared to when you stay in the same place.Error caused by the position of GPS satellitesThe camera automatically triangulates your current location when the camera receivesradio signals from 3 or more GPS satellites. The triangulating error allowed by the GPSsatellites is about 10 m (33 feet). Depending on the environment of the location, thetriangulating error can be greater. In this case, your actual location may not match thelocation on the map based on the GPS information. Meanwhile, the GPS satellites arecontrolled by the United States Department of Defense, and the degree of accuracy maybe changed intentionally.Error during the triangulating process
