data are not mixed with other data previously saved in the same hard disk.
For details, please refer to “5.6.6 Clear All HDD Data” at page 26.
Step1:Loose the screws on the upper cover and remove it from the DVR. Find the two
HDD brackets located on the DVR base.
Step2:Get a compatible HDD, and connect it to the power connector and data bus
connector.
Step3:Make sure the PCB side is facing up, and place the HDD between the HDD
brackets on the DVR base as shown below.
Make sure the other side of the HDD is contacted with the DVR base for
heat conduction.

the naked wires for further connection.
STEP 3: Twist the RS485-A and RS485-B wires of the RJ11 cable and the speed
dome camera together.
Twist the RS485-A (red) and RS485-B (green) wires of the RJ11 cable to the
RS485-A (brown) and RS485-B (orange) wires of the speed dome camera. To
protect the naked wires, use the insulation tape to cover on the twisted wires.
STEP 4: Connect the other end of the RJ11 cable to DVR.
Solder the RS485-A (red) and RS485-B (green) wires of the RJ11 cable to the
corresponding pins on the solder side of the optional D-Sub connector.
