On the internal rechargeable 
battery
This camera has an internal rechargeable battery 
for maintaining the date and time and other 
settings regardless of whether the power is on or 
off.
This rechargeable battery is continually charged 
as long as you are using the camera. However, if 
you use the camera for only short periods, it 
discharges gradually, and if you do not use the 
camera at all for about one month it becomes 
completely discharged. In this case, be sure to 
charge this rechargeable battery before using the 
camera.
However, even if this rechargeable battery is not 
charged, you can still use the camera as long as 
you do not record the date and time.
Charging method of the internal 
rechargeable battery
Insert charged battery pack in the camera, or 
connect the camera to a wall outlet (wall socket) 
using the AC Adaptor (not supplied), and leave 
the camera for 24 hours or more with the power 
off.
