4.6.1.1 Keyboard test
The objective of the keyboard test is to check the proper function of every key of the device. The application
displays the list of symbol corresponding to the individual buttons except the CANCEL key. When the User
presses the key, its symbol is "marked off" – disappears from the list of symbols on the screen.
When the last symbol is marked off, the application switches to the printer test.
The possible results of the keyboard test specified on the final printout include:
- OK – every key is pressed and every symbol on the screen is marked off
- NOK (failure) – when the User presses the CANCEL button at any time during the test (e.g. in the absence of
the terminal reaction to pressing the button or in order to accelerate the diagnostics procedure)
3. The application
displays the list of the
symbols of all the keys
(except the CANCEL key)
4.6.1.2 Printer test
5. The application
displays the confirmation
and makes a test printout
4. By once pressing every key results in marking off the
corresponding symbol on the display.
When the last symbol is marked off, the application switches
to the subsequent test.
6. The application displays the screen with the question about the printout
correctness. If the printout is correct – select YES; if incorrect – select
NO. Then the application switches to the subsequent test.
