3.3.2 Handling the different menuscreens.
The menu system consists of five basic screen types; menu-screens, readout-screens, tog-
gle-screens, input/storing-screens, and the quick read screens.
3.3.2.1 The menu screen
The menu screen is controlled by the key-buttons: <PREV> <NEXT> <ENTER> and <ESC>.
The menu options are formatted as a long list where each option holds one character line. If a
menu screen includes more than four options, a small arrow-indicator will be displayed in the
lower-right corner. This informs the user that more than four menu options are available. The
blinking arrow cursor left to the menu-text is controlled by the <NEXT> and <PREV> keys.
The <ENTER> key activates the menu options left to the arrow-cursor.
The <ESC> key brings the user one menu-level upwards or back in the menu-tree-struc-
ture.The menu scrolls down if the user pushes the <NEXT> key when the arrow-cursor is at
the lower line and the arrow indicator is displayed in the lower-right corner. The menu will in
the same way scroll upwards by pushing the <PREV>-key in a corresponding situation.
3.3.2.2 The readout screen
The readout screens display the various monitor and maintenance parameter readings. The
screens are entered by stepping through the menu options. The <ESC> key brings the user
back to the last menu-screen again. The parameter readings are continuously updated.

3.3.2.3 The toggle screens
The toggle screens offer the user to choose between two or more options. The options text is
enclosed by two blinking square-brackets. The plus «+» and minus «-» keys step through the
various options. The <ENTER> key activates the chosen toggle-option. The <ESC> keys
leaves the screen without activating any of the options.
