DVR time reset after power failure, for example, caused by a power outage, will cause the disorder of the recorded data,and users may have problems in searching the event clip they want. To keep the DVR time from resetting, a
non-chargeable lithium battery, CR2032, is installed in the DVR.However, the DVR time might still get reset when the DVR battery is low or even running out of power. If so, please
replace the DVR battery, CR2032, right away as instructed below.
Ø How to replace CR2032
Note: The lithium battery, CR2032, is a non-chargeable battery, and should be purchased separately.Please replace only with the same or equivalent type battery in case of danger.
Step1: Stop all DVR recording immediately to prevent the disorder of the recorded data. Then, back up therecorded data if necessary.
Step2: Power off the DVR, and disconnect the DVR power.
Step3: Remove the DVR cover, and find the battery on the mainboard. The battery is located close to the rear
panel.
Step4: Push the release as indicated below to remove the battery.
Step5: Get a new battery with the side of “CR2032” facing up, and install it to the mainboard.
Step6: Replace the DVR cover.
Step7: Connect to DVR power, and turn on the DVR.
Step8: Set DVR date & time, and resume recording. For details, please refer to “3.4 Date and Time Setting” at page
12, and “7.1.7 Record” at page 29.

MORE INFO
The positive side of the 2.1mm connector is in the center, and the outer part of the connector is the ground, or negative.
The wire with a solid line (or it may be a dashed line) is the positive wire. Confirm with a multi meter.
The connector is a 2.1mm.
12 Volts 500 mA
You can use this to power your cameras. Plug the power supply in to the "plug, and play" camera cables.
If you are using siamese wire then you can cut off about 6 inches from the 12 Volt plug. Attach the 12 Volt plug at the camera side of the siamese wire with butt connectors, and crimp them tight, and connect the wall transformer side to the DVR side of the siamese wire.
