Removal Procedures
These procedures require that you have access to the module that you are
removing. Refer to the exploded drawings, Figures 5--1 through 5--9 on pages
5--5 through 5--21, 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, do not touch the switch
contacts with your fingers. The oils on 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.
