Wi-Fi / Bluetooth – Using "LUMIX Sync"
•
When [Auto Transfer] is set to [ON], images recorded while remote operation is
running are automatically transferred to a smartphone.
If [Power OFF] is selected while there are still unsent images, sending is
resumed when the camera is next turned on.
•
When [Remote Wakeup] has been set, the Bluetooth function continues to work
even if the camera on/off switch is set to [OFF], so the battery will drain.
