Charging the built-in battery
The camera uses the built-in battery to remember the date and time.
If the camera is not turned on for more than a half year, the built-in battery runs out and when the <POWER> switch is turned <ON>, [BACK UP BATT EMPTY] may be displayed on the viewfinder screen for approx. 5 seconds.
In that case, charging of the built-in battery is complete by connecting an external DC power supply or a battery and leaving the camera turned off for approximately four hours. Set the date and time after charging is complete. Charging is disabled when the time code on the display window disappears with power turned off. To charge the battery, set [ON] in the main menu → [SYSTEM] → [SYSTEM SETUP] → [P.OFF LCD DISPLAY] and display the time code on the display window.
If [BACK UP BATT EMPTY] is still displayed in the viewfinder screen after charging when the <POWER> switch is turned <ON>, the built-in battery needs to be replaced. Consult your dealer.
