7 DATAGUARD OPERATION
This chapter describes how to operate firmware with the DataGuard feature.
This chapter is a supplement to the Operation chapter, so only the differences
will be covered here.
DataGuard is a firmware feature that provides support for 21 CFR Part 11. It
provides access control to the instrument via password protection and
maintains an audit trail of user operations. The default Administrator
password can be found in the Identification Records.
An overview of the menu structure is shown in Figure 7-1. (The single letter
shown following each menu option relates to the required level of access
authority, as dictated by DataGuard and described in the key at the bottom of
the page.) To move down the menu tree, select the desired menu option with
the arrows ( or ) and press ENTER. To move up the menu tree, press
CLEAR.
