Replacing Button Chassis
The X2's button chassis can be replaced. The replacement chassis must have the same button layout as
the original. To replace the button chassis, follow these steps:
1.
Pull airgap switch out.
2.
(If X2 already installed) Snap the wall plate off of its mount, and then unscrew and remove the mount.
Save screws.
Using a Phillips (PH1) screwdriver, unscrew the bottom-right screw that holds the button chassis in
3.
place (see figure 10).
4.
Apply pressure to exposed left edge of button chassis until it pops loose, and then gently remove
(see figure 11).

5.
If removing the chassis detached the light guide from the board, reapply the light guide. The light guide
is a thin, black rubber strip with chimneys on top (see figure 12). To reapply, fit the two pegs on the
underside of the light guide into the two square holes on the board.
Note: The light guide's orientation matters. Its surface should have a groove at the very bottom, just
above the last chimney.
Apply replacement button chassis immediately, applying equal pressure to all four corners to ensure
6.
that the new chassis snaps into place.
Note: Your replacement chassis must have the same button layout as the original.
Reapply the bottom-right screw that holds the chassis in place. Ensure airgap switch is pressed in fully.
