USING THE WEB INTERFACE
This section introduces the Web interface pages used in every-
day operation of the 525N monitor. Operational details of the
product that were covered in Section III, dealing with front-
panel setup of the unit, will not be repeated here in depth. In-
stead, page numbers from the earlier discussions will be cited
in lieu of presenting the detailed information redundantly.

is simply labeled

screen duplicates several front-panel programming options.
