this process for naming new checklists until all desired checklist
names are created.
When all done naming checklists, press the "Edit" box again to
get out of Edit mode (background of Edit box should now be
gray).
The second step is to create the checklist content. To create the
checklist content, select the checklist title that is to be filled out
from the directory list. First put the system back into checklist edit
mode by touching the "Edit" box again or using the bottom right
IFD knob to select it and then pushing the knob. This will
produce an empty grey checklist step item.
Touch or use the bottom right IFD knob to select the step to be
created or edited and this will put a bright blue outline around the
step. Touch the highlighted row a second time or push in the
bottom right IFD knob to generate a keypad. Type the desired
text (Note: there is no ability to manually generate upper case
characters) and then press the "Enter" button to accept. This will
generate another empty grey checklist step item below and
repeat the process as required. When done creating all the
desired checklist steps, press the "Edit" button in the top right
corner again to exit edit mode.
