The Raynger 3i Plus series has three soft keys (F1, F2, and F3) just below the LCD display. There is a
“Soft Key Bar” on the LCD above the three soft keys to define their active function. By using soft keys,
the instrument has a convenient menu function. Each menu item and function is explained in detail in
the following sections.
In addition to the soft keys, there are also the <Save> and <Return> soft keys below the LCD display.
Selecting the <Menu> soft key advances the menu to the next level. The following table shows the top-
