4.3 Statistics Functions/Diagnostics
4.3.2 LED Display Tables for Selection Options
(watch the LED display). Pressing the AzGrH button for a longer time (> 1 s ≤ 3 s) will bring you back to the object selection menu.
If the AzGrH button is pressed for more than 3 s, the system quits the statistics selection function and the display on the STEU board returns to 'normal'.
the objects CH, TVDS, block info and system info are listed in the table "Meaning of statistics function types".
The respective LED display is selected with the help of the table "Statistics function options". The table "Meaning after selection of statistics function type 2 - operating state" is relevant only to statistics function type "Operating state"
(function type 2; TVDS table only). See also Section 4.3.3 "Examples of Option Selection", page 47.
