Connecting Required Devices
Before powering on the unit, cameras and a main monitor should be
connected 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 any short-term devices shall be installed to the DVR as parts of the unit
system, such as USB ThumbDrive
®
or any USB devices, etc., make sure
those devices are connected only after the unit is powered on. The reason is
because the DVR can recognize the external devices only after the power-on
process is done completely.
