GPS Acquisition Status
LCD panel
GPS signal status is indicated by the <r> icon on the camera's LCD
panel and LCD monitor.
• Constant <r> : Signal acquired
• Blinking <r> : Signal not acquired yet
When you shoot while the <r> mark is lit, the image will be
geotagged.
When [Internal GPS] is selected, the <r> mark is displayed on the
camera's LCD panel even when the camera's power is turned off
because signals from satellites are constantly received. Also, the number
of possible shots will be lower, since it will consume more battery to
receive satellite signals.
Status details can be checked as described in "Viewing GPS
Information" (p.G-9).
