Charging the battery 8
With the battery removed from the camera, insert the jack plug from the battery charger
into the socket on the battery grip. Insert the battery charger into a standard (100–240V~
/50–60 Hz) domestic socket.
It will take about 12 hours to load the battery completely the rst time.
There are two types of battery charger. Please check here for the relevant description of
the LED indicator, etc.
 On (not ashing)  Battery is charging
 Slow ashing (0.8 Hz)  Charging is complete and condition is being maintained.
Or occasionally
Rapid ashing (3 Hz)  Deeply discharged battery is charging (with reduced current)
Please note that rapid ashing of the LED indicator is not to be expected. The battery
will not normally be so deeply discharged because the camera will shut down auto-
matically before complete battery discharge takes place. The indicator might also ash
rapidly for a few moments in some instances when the charger is connected to the elec-
trical supply. The normal indication is therefore either ‘not ashing’ or ‘slow ashing’.
