ATevo has a Lamp Test mode that is activated by pressing and holding the DOWN arrow button. The Lamp Test will turn ON all front panel LEDs (except for the AC ON LED) and keep them on until the DOWN arrow button is released. The AC ON LED will be lit during normal operating conditions because it is driven by the power supply, and is not under software control.
When DOWN is released, ATevo will briefly display the charger’s installed firmware versions, then return to the HOME screen and resume normal operation.
