4 SYSTEM OPERATION
4.1 Navigating the Menu Structure
The FCS has a 1/4 VGA full colour resistive touch LCD display. A certain amount of pressure
is required to engage the buttons, as is a certain length of time. To indicate the button has
acknowledged the pressure, it will turn colour as you press it and upon release will return to
normal. Press firmly and purposefully using your fingernail or a dull pointed instrument such
as a stylus to navigate through the menu. If the expected change doesn’t occur, reduce the
speed at which you are pressing.
After entering a menu item, the BACK button will return you one screen previous to where you
were. The HOME button will return you to the normal display screen, logging you out of the
password protected menu items.
Some screens have data fields that are yellow. If you press on the yellow data field, a numeric
(or alphanumeric) key pad will appear, allowing you to enter a value more easily than using
the + or - buttons.
