APPENDIX 9 DVR BATTERY REPLACEMENT
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.
