6. Do not operate if any problems are found
If there are any strange smell or sound from NVR, unplug the power cable and
contact the authorized dealer or service center.
7. Do not try to remove the upper cover
Warning: Do not remove the cap of NVR so as to avoid electric shock.
8. Handle with care
If NVR does not work normally because of hitting on the hard object, please contact
the authorized dealer for repair or replacement.
9. Use standard lithium battery (Note: Use the batteries attached or specified by
the manufacturer)
After cutting off the power supply, if the system clock cannot continue to work, please
replace the standard 3V lithium battery on the main board.
Warning: Turn off NVR before replacing the batteries, or you may be suffered from
serious electric shock. Please properly dispose of the used batteries.
10. Put the equipment in a place with good ventilation
The NVR system includes HDD, which produces large amount of heat during
operation. As a result, do not block the ventilation openings (on the top, bottom, both
sides and the reverse side) for cooling the system during operation. Install or put the
equipment in the place with good ventilation.
11. The attached power adapter can only be used for 1 set of NVR. Do not
connect more equipment, or NVR may be restarted repeatedly because of
insufficient power.
12. Prevent the equipment from water dropping or splashing. Do not place
objects containing water, such as flower vase, on the equipment.
