Figure 2-3 Removing the Keyboard Overlay
A. Notches
Do not wash the keyboard overlay in hot water. Do not attempt to clean the keyboard
overlay in a dishwasher.
3. Rinse off the keyboard overlay and thoroughly dry it.
The rubber keypad and/or keyboard assembly may be damaged if any key or LED
becomes trapped under the overlay while replacing the overlay. Make sure each and every
key and LED comes through its hole in the overlay before snapping the overlay into place.
4. Align the overlay with each of the keyboard keys and LEDs. Position your thumbs
along the front edge of the overlay near each end. Apply pressure on the overlay
toward the rear of the unit and then press down on the overlay in one continuous
motion. The front of the overlay should now be snapped into place. Snap the rear of
the overlay into place.
