1.6 On-Line Help System
Overview
The E2 On-Line Help is the primary source front-
panel/interface users will have to consult when seeking
instruction on properties, screens, menus, and trouble-
shooting of hardware/software problems. The on-line help
topics are designed to minimize the time the user would
otherwise have to spend searching through the manual to
find information. Press
 +  keys to open the
General Help menu.
To use on-line help from any screen in the E2 front
panel interface, simply press the E2’s permanent Help
 key. This opens a pop-up window containing either
information about the screen or menu you are currently on,
or information about the input, output, or setpoint you
have highlighted with the cursor (if available). After the
Help
 key has been pressed,  will open the Gen-
eral Help menu containing Troubleshooting options.
1.7 Software Licensing
Some applications in the E2 are available only when
activated with a unique license key that is obtained
through Retail Solutions. Software licensing (see Section
10.15, License Management) allows the user to activate
certain features in the E2, such as Web Services and third-
party controllers. Call your Retail Solutions sales repre-
sentative at 770-425-2724 for more information about
software licensing.
