APPENDIX 4 BATTERY REPLACEMENT
The 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 device time from resetting, a
non-chargeable lithium battery, CR2032, is installed in the device.
However, the device time might still get reset when the battery is low or even running out of power. If so, please
replace the device battery, CR2032, right away as instructed below.
 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 recording immediately to prevent the disorder of the recorded data. Then, back up the recorded data
if necessary.
Step2: Power off the device, and disconnect the power.
Step3: Remove the device cover, and find the battery on the mainboard.
Step4: Push the release as indicated below to remove the battery.
