To securely decommission the device:
Prepare your tool. A #8 Phillips head screwdriver is necessary.
Ensure that the device is disconnected from power and any other cables.
Turn the device face down, exposing the rear of the device.
Using the Phillips head screwdriver, remove each of the eight screws. Four of the screws, screw numbers 3, 4, 5, and 6, are covered by the rear cable cover. You must remove the cable cover to access these screws.
Screw #4 is covered by a tamper-evident security label. Push the screwdriver through this label to access the screw.

Once all the identified screws have been removed, carefully separate the top housing plastics from the bottom 1mm, then pinch the top and bottom housing back together ensuring proper fit.
Reinsert all of the screws previously removed. Tighten each screw completely.
Insert the power cable and power up the device.
Turn the device face up showing the display and keypad. Verify that the unit is in an "Active Tamper." You should see the TAMPER message displayed on the screen.
