The function of each button changes depending on what
operating mode the display is in.
The SCROLL button operates once it’s briefly pressed. It has
two functions:
• In data display mode, it scrolls through the display
pages.
• In programming mode, it scrolls through the menu
items and allows changing a selected digit when
entering numbers.
The SELECT/ENTER button normally operates once it’s
released. The button function changes depending on the time
the button is pressed:
• In data display mode, when pressed briefly and
released, it scrolls through the display views; a long
press for more than 5 seconds switches to
programming mode.
• In programming mode, when pressed briefly and
released, it moves from one menu item to another; a
long press for one second selects a highlighted menu
item allowing to enter a submenu or to store a
changed item.
In data display mode, when the SCROLL and
SELECT/ENTER buttons are briefly pressed together and
then released, the current display returns to the start page;
in some pages, an extended press for more than 5 seconds is
used as a “shortcut” for immediate entering a specific
programming menu.
The DEMAND RESET Button
The DEMAND RESET button functionality is described in the
following table.

more than 2 seconds calls the maximum demand reset menu.

by disabling the manual demand reset in the End of Billing

EM920 by default. See

in your meter.

button clears the test energy registers.
