CAUTION: Make sure the system unit On/Off button is in the "off" position before
removing the system cover and panels.
To remove the top cover and side panels, refer to Figure 7–2 and follow these steps:

4. Turn the front door lock to the right to unlock the door.
5. Pull down the top cover release latch on the front of the system until it catches

6. Grasp the finger groove at the rear of the top cover and pull the top cover
straight back no farther than 2 inches, and lift up on the cover.
7. Pull the top of the side panel back, then up and away from the unit to remove it.
(Repeat this step for the other panel.)
