3. When the selected option is a function on the MAIN MENU
or any SUB MENU screen, the function name appears with
an arrow next to it. In some cases, the item in the menu is
the parent of another SUB MENU; in other cases, the item in
the menu is the parent of a MODIFIABLE ITEM.
If the selected option is a MODIFIABLE ITEM, the ARROW KEYS are
used to modify the value of the item. A modifiable item is flashing. The
ENTER key is then used to accept the value and move you to the next field to
continue programming.
4.4.3 ESCAPE
The ESCAPE key is used in several context-sensitive ways.
4. When showing the CH4/NMH analysis modes, the ESCAPE
key temporarily clears any present alarms. However, if the
alarm condition is still present, the alarm will re-occur when
re-detected. Also, pressing the ESCAPE key clears the
messages generated by incorrect gain settings (i.e. bad span,
gain too high).
Note: In display mode 2, if the ESCAPE key is held down,
then the TOTAL AREA for the most recent pass of the
other mode is temporarily displayed (if current is CH4,
then NMH TOTAL AREA is displayed).
