3.1 Turn on
Plug the power supply and turn on the power supply switch. Power supply indicator light
shining indicates turning on the video recorder. After the startup you will hear a beep. The default

corresponding channel is shining and the DVR is working normally.
Note: 1. Make sure that the input voltage corresponds with the switch of the DVR power supply.
2. Power supply demands: 220V±10% /50Hz.
Suggest using the UPS to protect the power supply under allowable conditions.
