7. Using a small flat blade screwdriver and a small piece of rubber or similar material, carefully pry the
eight (8) Main Keypad Bezel locking tabs free of the main body of the case. The following tips help with
the removal process:
• The flat blade screwdriver width must be less than 3.5 mm (0.13 inch) wide and as thin as
possible. If available, recommended is a screwdriver made of fiberglass or other material that will
not scratch the bezel.
• As each locking tab releases, the bezel comes up a bit.
• The basic technique is to place the protective piece of rubber (or similar material) next to the slot,
press the screwdriver straight in between the case and the bezel, and then gently lever the
screwdriver AWAY from the bezel using the rubber as protection for the case finish.
Protecting Speaker While Removing Bezel:
8. When the eight locking tabs are released, lift up the bezel carefully, disengage the speaker from its
mounting pins (it stays attached to the underlying Main Keypad PCB), and set the bezel aside.
9. Protecting the Speakers wires, start at the bottom of the Main Keypad Rubber Membrane and lift it up.
10. Hold the edge of the Speaker with one hand and remove the Membrane from each side, exposing the Main
Keypad PCB.

Note
The Speaker sits on top of the Main Keypad PCB and the keypad rubber membrane. It is held in
place by four locating pins on the inside of the keypad bezel. When the keypad bezel is removed, the
speaker is held only by the fragile connecting wires. Use care not to damage the speaker wires when
removing or replacing the keypad rubber membrane or the PCB.
