Status lights for iNID Power Supply Unit

LightStatusIndicates
PowerOffPower supply is not receiving power from either AC or the battery.
Solid GreenPower supply is running on AC power.

Button functions for iNID Power Supply Unit

ButtonLocationFunction
Reset ButtonUpper left side panel, identifiable by a surrounding red circleWhen pressed for up to 9 seconds, the Reset button reboots the outside unit. If the button is pressed for 10 or more seconds, it resets the outside unit to the factory settings.
Do not press the Reset button unless you are instructed to do so. Doing so may reset the outside unit to the factory default settings, and you will lose your personal settings.
Silence Alarm ButtonBetween the Power and Battery indicatorsIf AC power is interrupted for any reason, a continuous tone indicates that the power supply is running on the backup battery. Pressing the Silence Alarm button within 15 seconds immediately silences the audio alert. (The tone stops automatically after 15 seconds).
When the battery needs to be replaced, a chirp sounds intermittently unless you press the button to silence it for 12 hours. The chirp resumes after 12 hours if the battery is not replaced.
