entries until a required reset entry appears in the
window.
2. Press briefly SELECT/ENTER button to highlight the
“Do” entry.
3. Press and hold the SELECT/ENTER button for more
than 5 seconds until the “Do” entry is replaced with

you will not be able to highlight the lower action window.
NOTE
You may not be allowed to reset the billing maximum
demands in the event this action is not enabled for the front
display in the Device Options setup, or it has been just
performed once at the same day – the meter does not allow
repeated triggering an end of billing period within one
calendar day.
