Button Description
EXIT The EXIT button lets you exit a menu option, which then places the
unit in the next higher level in the menu hierarchy. If you are in the
process of editing an option and pressing the
EXIT button, you will
exit that screen without any changes having been saved. If you are in
the main menu and press
EXIT, you will be logged off the unit.
SCROLL The SCROLL button lets you review the available options for a given
level in the menu hierarchy or scroll through possible settings for a
parameter. The
SCROLL button is also used to set alphanumerical
values, where applicable, by scrolling incrementally through digits 0–
9 or letters A–Z and a–z.
SELECT The SELECT button lets you select the currently displayed option or
value for a given field, and is also used to enter an “edit” mode for
parameters that require user-specified input. The
SELECT button is
also used to confirm certain actions or settings.
