Removal
Using the tip of a small straight bladed screwdriver or other thin edge tool peel back an edge of the overlay from the
top housing. Then grasp that edge with your fingers and remove the overlay the rest of the way.
Installation
1. Select the appropriate replacement overlay.
2. Prior to installing the new overlay ensure that the contact surface area of the top housing is clean and free of any
adhesive residue left over from the overlay that was removed.
3. Remove the adhesive release liner from the new overlay and install the new overlay pressing thoroughly across the
entire area to ensure adequate adhesion.
