Factory reset (Hard reset) Locate the reset pin hole on the rear panel – to the left of the Power ON/OFF button. Use a paper clip or other thin object to press in the hole and hold for at least 6 seconds. Release. Additional info: the Power LED on the front panel will blink three times in red when you release the reset button. Then it will become green once the default settings are restored.
