6.3 Keypad/Option Board Disassembly
1. If the disassembly of the keypad printed circuit board is required, open the catches on the
keypad retainer and lift the wire assembly up. (See Figure 4-6.)
2. Lay this wire assembly to one side.
3. To remove the keypad retainer shield:
a. Insert the keypad retainer tool (part number 6685707Z01) in the opening at the end of
the keypad retainer arm tab.
b. Pry the tab away from the side of the front cover until it moves past the ledges on the
side wall. Duplicate this procedure for each of the four retainer arm tabs.
4. Note that the two “top hooks” are still held underneath the front cover—right below the
speaker. Lift the keypad retainer out of the front cover; then, lift and pivot the two hooks out of
the front cover.
