Check whether the source power is sufficient.

Does it keep in the starting-up logo frame?

Physical damages have occurred to the hard disk.
The system guiding is abnormal.

Starting-up is very slow?

The hard disk error will lead to repeated hard disk check by the DVR host computer, thus causing slowly starting-up.

The host computer restarts repeatedly?

Please check power supply of the host computer. After hitching a lot of hard disks, it’s possible that the host computer starts up repeatedly due to insufficient power.
Please disconnect the gridline, and then check if the machine operation is normal. Network with serious failures is also likely to lead to repeated starting-up of the host computer.

Check whether there is anything wrong with hitching of the hard disk, and change the failed one in time.

The host computer is unable to identify the poor U-disk due to its poor compatibility. It’s recommended to test more than one U, or to use new-brand U-disks.
The USB port contact is poor. During updating, the voltage fluctuates dramatically.

The image on the invigilator or the TV set is black and white?

absolutely consistent. If not, please set the invigilator or the TV set system option in the automatic
identification state.

Check whether the invigilator power supply is opened, and whether the invigilator’s brightness is in its lowest condition.
Check whether the video cable is properly connected, and whether there is anything wrong in the circuit.
