The camera has 4 batteries – 2 batteries must be always in charge on the chargers under the table. Make sure the batteries are installed properly on the chargers when replacing them – the digital screens should show the charge if working properly. If the screens are blank after you install the batteries, try to re-insert them. If it is still not working, unplug the charger and re-install batteries.

Install the battery in the digital back. You do not need to remove the digital back from the mount to install the battery. Release the notches on the back of the digital back to open the battery compartment. Insert battery with metal connectors facing down and inside the compartment. Do not force the batteries into the digital back. Close the battery compartment.
