The Evaluator has an LC-Display with a resolution of 240×128 dots, five control buttons and three LEDs that indicate the current system status.
As soon as the Evaluator is powered up, the initial info screens are shown for several seconds, and then the display switches to default screen (shown in Fig.4.2 User Manual)

The SiCOMS® system information and settings are organised in a tree-like menu. The user can view the menu elements on the LC-display, move between them and change some system settings using Evaluator buttons. Changing of system settings is only possible if the PIN is entered before, otherwise the system settings are read-only.
