The MENU button authorises you to select a menu from the 10
main menus that are available. Each time you press this button
one of the 10 LEDs lights up in turn alongside each of the
icons representing a main menu. The active menu is the one
against which the LED is lit. If a menu is empty then its LED is
not lit. To scroll quickly through the menus, hold the MENU
button down.
4.3.2 - Selecting a menu item
The up and down Arrow buttons let you scroll through the
menu items. Menu item numbers are displayed in the two-digit
display. The item number increases or decreases every time you
press the up or down Arrow button. The menu items that are not
in use or incompatible with the configuration are not displayed.
The value or status associated with the active item is displayed
in the four-digit display. To scroll quickly through the items,
hold the up or down Arrow button down.
The following example shows how to access item 3 in the

4.3.3 - Modifying the value of a parameter/access to a sub-
menu
Press the Enter button for more than 2 seconds to enter the
modification mode or to select a sub-menu. This lets you correct
the value of an item or select a sub-menu with the aid of the up
and down Arrow buttons (if you are authorised to overwrite the
item concerned). When modification mode is activated, the LED
for the main menu to which the item belongs as well as the 2-
digit display flash in the menu block. Once the required value is
obtained, press the Enter button again to validate the change or
to access the sub-menu. The LED for the menu to which the
item and the 2-digit display belong then stops flashing,
indicating that modification mode no longer applies.
In modification mode, the value to be modified increases or
decreases in steps of 0.1 every time you press the Arrow
buttons. Holding one of these buttons down increases the rate
of increase or decrease.
NOTE: The access to a sub-menu may require entering a
password. This is automatically requested. See section
4.3.11.2.
The following example shows how to modify the value of item
