The green LED informs the user that the flaw detector is
switched On.
The below-located LED indicates the battery charging. The
yellow light indicates that charging process is going on; the green light indi-
cates that charging is completed.
Two red indicators show actuation of the automatic defect signalization
function (AFAS) for the first and the second strobe
correspondingly.
The keys bear characters describing their main functions. English symbol
names of the keys are used for unification of the design and operating docu-
mentation on the instrument provided that it could be used in various countries.
The user controls the main functions and parameters by means of the
icon selection keys, the functional keys (F), located just below the screen. The
corresponding information icon is provided above each key.
The user selects active parameters and adjusts them by means of the
keys of the control keypad. Their operating process is similar for different
operating modes of the instrument in order to provide intuitive learning of
the user. In other words, symbols on these keys describe the principle of the
action carried out.
Some keys allow working in the auto repeat mode with acceleration pro-
vided that the key is being pressed and hold for longer than 1 second.
A brief description of the keys in the main modes is presented in the Table 2
