GPS Acquisition Status
When [ Mode 1 ] is set, the camera will continue to receive GPS signals at
regular intervals even when the power switch is set to < 2 >.
Therefore, the battery will drain faster and fewer shots can be taken. If
you will not use the camera for a prolonged period, set to [
Disable ].
When [ Mode 2 ] is set, the camera will continue to receive GPS signals at
regular intervals even during auto power off. Therefore, if auto power off
is prolonged, the battery will drain faster and fewer shots can be taken. If
you will not use the camera for a prolonged period, set the power switch
to <
2 >.
The GPS antenna is located in front of the hot shoe. The GPS signal can
be acquired while an external Speedlite is attached to the hot shoe, but
the acquisition sensitivity will slightly decrease.
GPS Receiver GP-E1 (sold separately) and GP-E2 (sold separately)
cannot be used.
