| Delicately lift both short ends of the label until two Phillips screws are revealed. Remove them. Next, take a plastic spudger and insert it carefully, starting below one of the antennae. Pry the case open by moving the spudger around. The plastic case is rather soft and should open easily. | **Note:** This will void your warranty! |
| | |
| | To open the case, you need to unscrew the two screws under the sticker and snap off the plastic clips around the perimeter. Use a plastic spudger so as not to marr the case. Plastic is soft and should yield easily. |
