Getting Started
1. Familiarize yourself with the instructions throughout this manual.
2. Check that you have all the necessary parts and tools. Refer to
Parts and Tools
on page 3.
3. If possible, back up all essential video before you install a new hard disk drive. If your unit contains two hard disk
drives, back up all essential video on the unaffected drive as well.
4. Shut down the DX4000 DVR unit. Refer to the DX400 installation or operation manuals for instructions on shutting
down the unit.
5. Unplug the power cord from the wall socket and then from the rear of the DVR.

Removing the Power Cord
6. Ensure that the DX4000 DVR and all of its components are protected from electrostatic discharge (ESD). Before
handling any electronic components, you should take steps to ground yourself properly so that any built-up static
electric charges are dissipated away from the unit. The most effective method for combating ESD is to use a properly
grounded wrist strap (refer to Figure 2). These wrist straps are designed to be plugged into specially-designed mats.
WARNING:
For safety reasons, you must remove the power cord because current continues to flow through the
DX4000 even when the unit is off. Remove the power cord from the wall socket first and then from the rear of the
DVR. It is critical that the unit be unplugged for your safety.
