Supplying power from a wall outlet (wall socket)
You can use the camera while power is supplied from a wall outlet (wall socket) by using the AC Adaptor (supplied).
Notes • When using a mobile charger as a power source, confirm that it is fully charged before use. Also, be careful of the remaining power on the mobile charger during use.
