Press down on the grooved plastic with your thumbs.

Push the back cover in the direction indicated by the small arrow on the grooved plastic. The back cover should slide right off.

Once you have the back cover off, the camcorder should look like this.

Look on the battery for a model number to assure that you acquire the correct replacement part.

The camcorder model number is located in the red box. Verify that you have a Jazz HDV178.

-
Use a small plastic pry tool to gently pry off the silver strip on the top of the camera.
-
Make sure to run the tool under the outline of the strip as you pry it off so the plastic does not snap.

Locate the side of the camcorder beneath the lens and on the opposite side of the wrist strap.

Remove the silver strip using the same process as the previous step.

Remove the two 4 mm screws that were hidden under the cover.

Pry off the rubbery cap, which covers the buttons. Use the same process as the previous two steps.
