Using the GPS Function
Carrying the Camera when Using the GPS Logger Function
When carrying the camera, make sure the GPS signal receiver is pointed
toward the sky whenever possible. When keeping it in your bag, try to keep it
in an outer pocket with the GPS signal receiver pointed toward the sky. Doing
so will make it easier to receive GPS satellite signals.
Environments where GPS Signals Cannot be Received
• Since it may not be possible to receive GPS satellite signals correctly in the
following situations, the camera's positioning data may not be recorded or
the recorded position may differ from the actual position.
Indoors Underground Near buildings or valleys In tunnels or forests
Near high-voltage power lines or mobile phones that use a frequency of
1.5 GHz When the camera is inside a bag or suitcase, etc. Under water
(using separately-sold waterproof case (p. 228) ) When travelling long
distances When moving to a different environment
• Since the position of GPS satellites changes over time, the camera's
positioning data may not be recorded, the recorded position may differ from
the actual position, or the camera may record a false route even if it was
used in the same place without moving.
• It may take some time to receive a signal from GPS satellites after
switching the battery, or if the GPS function has not been used for a long
time.
• If the camera's location information is not recorded, incorrect information is
recorded, or it takes a considerable amount of time to receive GPS satellite
signals, turn off the camera and remove the battery, then reinsert the
battery after more than one minute has elapsed. This will reset the GPS
function, which may enable recording of correct information.
