case, especially to the bottom side of the unit.   
 
 NOTE: Be sure not to remove the rubber feet, and always leave 
a space for air ventilation on the unit’s bottom side.

Connecting Devices to the Unit 
This section lists some important notices that should be read before 
making any connections to the MPEG-4 DVR. 
 
NOTE: Connect short-term devices, such as USB ThumbDrive
®
USB CD-ROM, USB Hard Disk Drive, etc., only after the unit is 
successfully powered up. 
 
Connecting Required Devices 
Before power up the unit, you should connect cameras and a main monitor to 
the unit for basic operation. If needed, connect a call monitor for displaying 
full screen video of all installed cameras in sequence. 
 
Connecting Short-term Device 
If you plan to install any short-term devices to the MPEG-4 DVR and use 
them as part of the unit system, such as USB CD-ROM, USB Hard Disk Drive, 
etc,  make sure those devices are connected only after the unit is 
powered up.
 Because MPEG-4 DVR can recognize the external devices 
only after the power-up process is done completely.
