The initial battery charging process can require anywhere from one to three hours, so don't expect to use the camera immediately after taking it out of the box.
If your camera uses disposable AA or AAA batteries, you simply have to insert the batteries in the camera.
If, however, your camera requires a rechargeable battery, you'll have to charge it before you can use the digital camera. Some cameras use a separate charger unit (as shown here), while other cameras charge the battery inside the camera.
