Keyboard Functions
The keyboard contains four pushbuttons and each has
separate functions (SCROLL-Down, SCROLL-Up, MODE
and Change-Level). The MODE and Change-Level push-
buttons, when pressed together, provide a SAVE function.
1.
SCROLL Down-Up pushbuttons (o), see Fig. 20.
2.
Change Level pushbutton (
«
), see Fig.21.
The Change-Level pushbutton is used to change
between the first hierarchy of selectable messages
to a subset of selectable messages. The Change-
Level pushbutton can also be used to change from a
subset message to a first level selectable message.
The symbol (>) located on the second line in the
lower right corner of the KDM represents a first level
hierarchy of selectable messages. The symbol (<)
located on the second line in the lower right corner
of the KDM represents a subset of selectable mes-
sages.
3.
MODE pushbutton, see Fig. 22.
The MODE pushbutton instantaneously switches
the display from a
second-line-selectable
message
to
second-line-preempted
message. The sixty sec-
ond timeout function also can be used for this task.
The MODE pushbutton will work only if there is a
second-line-preempted
message or lockout mes-
sage.
4.
SAVE function; see Fig. 23.
The SAVE function enables users to identify the
selectable message they want to view upon power
restoration. The second line selectable message will
be restored to the most recently saved selection
when power returns. The SAVE function is performed
by pressing and holding the MODE key and then
pressing the Change-Level pushbutton (
«
). The sec-
ond line of the display will briefly note “…SAVING…” to
confirm the key press.
