Removal Procedures
These procedures assume you have access to the module that you are removing.
Refer to the exploded drawings on pages 5--4 through 5--12 and to Figures 4--1
and 4--2, on pages 4--7 and 4--8 to determine which trim and or modules to
remove.
CAUTION. When removing or installing the keypad, make sure you do not touch
the switch contacts with your fingers. The oils in your fingers will degrade or
damage the switch contacts. To help prevent damage to the keypad use cotton
gloves when removing or installing the keyboard pad.
