Once power is removed from the unit, press and hold the factory reset switch for 4-5 seconds, continue holding the reset switch and plug the DVR’s power supply back into the unit, you will hear a beep. Continue holding the reset switch and allow the device to initialize for 20 – 30 seconds and then release the switch.
