Charging the built-in battery
The date/time set in the camera is maintained by the built-in battery.
The built-in battery may be consumed when the power of the camera is not turned on for approximately a half year.
If [BACKUP BATT EMPTY] is displayed in the viewfinder for approximately five seconds when the <POWER> switch is set to <ON>, the built-in battery
has been consumed.
Charge the built-in battery with the following procedure.
1
Make sure that the <POWER> switch is <OFF>.
2
Connect the batteries or the external DC power supply to the camera.
For details on the connection of batteries or external DC power supply, refer to “Power supply” (page 148).
3
Leave the camera for approx. four hours.
The built-in battery will be charged.
Make sure the settings for the date/time and timecode after the built-in battery has been charged. Set the date and time of the internal clock when
the [SET DATE AND TIME] is displayed in the viewfinder.
4
Set the <POWER> switch to <ON>, and check that [BACKUP BATT EMPTY] is not displayed in the viewfinder screen.
Replacement of the built-in battery is necessary when [BACKUP BATT EMPTY] is displayed even after the built-in battery has been charged.
