8.3.6 Keyboard test (menu option)
Once test has started you must press every key position on the keyboard in
sequence. Starting at top left–hand corner (key position ’1’) work from left to
right, then do the same for next row down, and so on. At each correct key press
the machine will produce a normal BEEP tone and the displayed PRESS KEY
number will increase by one. However, an incorrect key press produces a
different, and slightly shorter BEEP, and the displayed ”PRESS KEY” number
will remain the same. When test is completed successfully, test result is printed.
