User Interface (UI)
The LT-3100S GMDSS system is controlled from the LT-3110S Control Unit, which is the interface for
operating and configuring
the system. The control unit has a 4.3” TFT
-LCD display, supporting day and night
modes. The layout of the display and buttons is illustrated in Figure 31.
The control unit buttons, functions and features, are described in the following groups:
•
Power & DIM button
: The power button can power off the system by pressing the button for 5
seconds. A pop-up box will show the action, and a counting is showing the count down until the
system is powered off. If the external power source to the system is re-powered, then the system
will power on. To activate the DIM functionality, press the Power & DIM button shortly. Short press
(1 < s); brightness level will change between 7 levels. Long press (
≥
1 s); will change the display
mode. The display brightness level and display mode can be changed from the UI menu as well
(Menu -> Settings -> Display).

a Distress Alert. A Distress Alert window will be visible as soon as a Distress Alert has been

alternative to use the off-hook button is to lift the handset out of the cradle. If the off-hook button
