These procedures assume you have access to the module you are removing. Use
the tables to determine which trim and/or modules to remove to gain access. (See
Table 3-4 on
page 3-9.) (See Table 3-5 on page 3-9.) A figure is also provided
as a quick reference for customer replaceable module locations. (See Figure 3-1
on page 3-10.)

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 w
