Figure 1-3. FB107 Touchpad with Open Cover
To use the Touchpad, you open its protective cover and touch the
screen. Two light-emitting diodes (LEDs) at the top of the Touchpad
provide visual signals on the Touchpad’s operational status. The green
LED indicates successful “touches”: each time you touch the screen, the
green LED flashes to verify that the Touchpad has acknowledged your
entry. The green LED also can flash once every three seconds if you
have set the power savings mode (see Section 1.2.2). The red LED
signals alarm or integrity issues, and coordinates with other visual
Touchpad clues (such as an on-screen asterisk, i, or a) to identify the
area of concern. See Chapter 3, Using the Touchpad.
1.2.1 Display Mode
The Touchpad has two operational modes, Normal and Basic List
Mode (BLM). When you open the cover, the Touchpad displays the
“idle state display” (typically the Emerson Process Management logo):
