Keyboard Functions
The keyboard contains four push-buttons with separate
functions (SCROLL-down, SCROLL-up, MODE, and
CHANGE-LEVEL). The MODE and CHANGE-LEVEL, when
pressed together, provide a SAVE function. When in the Setup
Screen—Mode and Change Level serves as Menu or Enter.
1. Down-up arrow push-buttons. See Fig. 10. The down-up
arrow push-buttons are used to scroll through the
selectable messages. The double-headed arrow ( ),
which is located in the lower left position of the second
line of the display, represents the down-up push-buttons.
The down-up push-buttons can be pressed to display the
selectable messages one at a time or held down to scroll
through the selectable messages at the rate of two per
second. When the last item of the selectable message is
viewed, the display wraps around and displays the first
selectable message again.
2. The
push-button, see Fig. 11. The
push-button
is used to change between the first hierarchy of
selectable messages to a subset of selectable
messages. The
push-button 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 display, represents a subset of
selectable messages.
3. BACK push-button, see Fig. 12. Use the BACK
push-button to instantaneously switch the display from a
second-line selectable message to a second-line
preempted message. The sixty second time-out function
can also be used for this task. The BACK push-button
only works if there is a second-line preempted message
or a lockout message.
