Navigating the Menus 
Operating the medTester 5000C is as easy as pressing the function key on the 
top panel that corresponds to the desired menu item in the display. There are 
five function keys marked 
F1
through
F5
below the display (see the figure
below). The function keys select the menu functions that appear in the display 
just above them. The medTester 5000C is operated through menu choices in 
a tree-like structure. When you power on the medTester, the first menu you 
see sits at the top of the tree. As you make menu choices, you move to lower 
levels, or branches, of the tree. The menu you see below is the main menu. 
Note the right arrow located at the right edge of the menu. Whenever you see 
a right arrow on a menu, it indicates that there are more menu items at the 
same level. Access those items by pressing the right arrow key on the 
keyboard. What you then see on the display is:
