• Alarm and event information.
• Current time and date.

6.4 How the buttons work
The buttons let you:
• Move around the menus.
• View data stored in the 795x – VIEW mode.
• Edit the data – EDIT mode.
Some buttons do different things according to where you are in the menu system. For example:
ENTER button T his button does nothing until you get into EDIT mode. After you have
edited the data of a parameter, pressing ENTER accepts the changes
and puts the 795x back into VIEW mode.
c button When you move through the menu structure this selects any menu
choice shown against the button. However, when in VIEW mode,
pressing c lists the display units.
