Olympus 850SW Battery Replacement

Locate the battery compartment on the bottom panel of the camera.

Using a PH00 Phillips Screwdriver, unscrew the one screw located on the latch.

Find the arrows on the compartment, remove the small black plastic piece, and release the latch.

Allow the latch to completely open and insert the battery, with the writing side up.

Close the latch. You will hear a click when the compartment is fully closed.

Place the small black piece back in its' place.

Place the metal cover back over the closed latch, and screw the screw back in.
