To exit the Time Show submenu, press the SEL push-button. To exit the Time submenu,
select the Return line and press the SEL push-button.
Date submenu
This submenu is divided into two items that allow the user to display or set the current date.
●
Date Adjust: select this item after each power-up in order to set the current date. If the
time and date have not been configured before, a message is displayed, prompting the
user to set the time and date or to exit to the upper submenu.
The user is requested to set the current date to be stored in the application memory.
The date is displayed as Year, Month, Week Nbr, Day Nbr (number of the day in the
year) with the selected day shown in the month. There is no default date since the user
has to set the date at least once.
Once the submenu has been selected, the user starts by setting the year, then the
month and the day of the selected month. The month and the year are selected using
the UP or DOWN push-button. For the day, the UP, DOWN, RIGHT and LEFT push-
buttons can be used. Press the UP push-button to display the current value plus one;
press the DOWN push-button to display the previous value. To confirm the selected
month, press the SEL push-button. The display then jumps to the year configuration.
The same procedure is applicable for the year configuration.
After configuring the day, press the SEL push-button to store the entered value and exit
to the Date submenu. The current date value is then shown and you can change the
setting if required. The messages shown in
Figure 21 , Figure 22 and Figure 23 are
successively displayed on the LCD when this submenu is selected.
