M3SR Series 4100 Operating Concept
3.2.2.1 LEDs
The control unit has the following LEDs to indicate the status:
• LED ON
The LED is lighted if the control unit is switched on.
The LED blinks if the control unit is switched off (= standby).
• LED CU
The LED is lighted if the control unit is fully operative.
• LED GO
The LED is lighted if the control unit is connected to a radio (see sect. 3.3 Control and
Monitoring of Radio and Control Unit) and the radio is fully operative.
• LED G
Not used when controlling for R&S M3SR Series 4100 radios.
To test the proper operation of the LEDs see sect. 3.5 Control Unit Maintenance.
3.2.2.2 Graphical User Interface Design
All the graphical elements displayed on the screen form the graphical user interface (GUI).
As all the information and control elements necessary to fully control and monitor the radio
cannot be displayed at once, the GUI is organised in menu pages. The GUI consists of many
menu pages organised in a menu tree with hierarchical structure (see ”Menu Organization”
on p. 3.20 and sect. 9 Drawings).
3.2.2.3 Menu Page Design
Each menu page consists of up to 15 softkey labels arranged around the screen, a menu
header and a menu central area.
The softkey labels are software-assigned depending on the selected menu. As softkey labels
and softkeys are essential in the operating concept, there follows a separate section about
softkeys (see ”Softkeys” on p. 3.16).
The menu header design is identical for all menu pages. It consists of a menu number, a
menu domain symbol, a menu title, the connected radio (e.g. connection status), the type of
the radio control session and icons indicating radio states and modes.
The central area depends on the selected menu. It contains labels, bar graphs, editors, a sta-
tus line, folders etc.
