Restoring Programming After an Outage

Periodically, the programming and the corresponding date/time are stamped to the 4iE’s internal memory. This is then overwritten when the next stamp takes place. When power is restored following a power outage, the device reverts to the most recent stamp taken.

Refer to the Operating Manual for the WiFi version and non-WiFi version if you need assistance with programming.
