menu screens. Using the pushbuttons, the user can scroll through the menus and
access information or control choices for UPS operation, status, diagnostics, set-up
and tests. The main menu and sub-menu selections are described in the following
sections.

successively pressed. The UPS automatically shows the
default screen if there is no keypad activity for
3 minutes, or if warranted by a mode change or device
failure.

sub-menu screens is gained by pressing the Scroll key. To
return to the main menu, press the
Menu key.
