digital still cameras
A digital still camera is powered by a battery. A camera will have a compartment into which you insert the battery.
On the Canon Rebel, PowerShot G1 and G5, _the compartment is on the bottom of the camera. On the Pro1, the compartment is on the side. Push the button labeled BATT. OPEN in the direction of the arrow. Then to the right, place your thumb on the arrow and slide the battery compartment door to the right until it opens.
Swing open the door and insert the battery into the slots in the compartment, with the arrow on the battery pointing in.
Close the door, which will press the battery all the way into its slot, and slide the door to the left to lock the battery in the compartment.
To remove the battery, open the door and slide the small holding latch to the side. The battery will pop out.
