USE AND FUNCTIONING
3
SHIFT KEY: Enables the entry of alphabetical
characters (written in white on the keyboard) when
followed by the pressing of a numeric key: for example
if you want to enter the alphabetical character “A”, you
have to press: <SHIFT>+<7>.
The number of times the SHIFT key is pressed
determines the choice of alphabetical character: for
example if you want to enter the alphabetical character
“N”, you have to press <SHIFT>+<SHIFT>+<5>, if you
want to enter the alphabetical character “X”, you have to
press:
<SHIFT>+<SHIFT>+<SHIFT>+<2> and so on.
The fourth time the SHIFT key is pressed, the SHIFT
function is disabled. The SHIFT function can also be
disabled by waiting for a time-out of 2 seconds after
being pressed.
By pressing the <SHIFT> key followed by the <RIGHT
ARROW> key, the graphic display’s contrast increases
to the allowed maximum, and then returns to 0 value.
NUMERIC KEYS: allow the entry and display of the
main numeric symbol. If the <SHIFT> has first been
pressed, the choice of alternative alphabetic characters
will be activated.
BACKSPACE KEY: deletes the last character entered.
SPACE KEY: allows the introduction of a blank space. If
the <SHIFT> has been pressed previously, the choice
of alternative characters will be activated.
ENTER KEY: allows validation of what has been typed.
RESET: by pressing <SCAN> + <ON/OFF> keys
simultaneously, a system reset is performed.
