Safety Precautions
Please carefully read the following safety precautions so as to avoid personal injuries and prevent the equipment and
other connection devices from being damaged.
1. Power supply
Never operate the equipment with any power supply other than the one supplied in the box.
2. Never push objects of any kind through the openings of the NVR
Never push objects of any kind through any openings of the NVR to avoid electric shock or damage to your NVR.
3. Do not place the NVR in a dusty environment
Dust could affect the connections and damage the electronics.
4. Do not place the NVR in a wet or humid environment
Do not position the NVR in a location that is likely to get wet or humid such as outdoors or in a basement. If the NVR
comes into contact with water, unplug the power cable immediately and contact your local dealer.
5. Keep the surface of the equipment clean and dry
Use a soft slightly damp cloth to clean the outer case of NVR and make sure it is dried straight away (do not use
liquid aerosol cleaners).
6. Do not operate if you notice any unusual problems
If you notice any strange smells, sounds or smoke coming from your NVR, unplug the power cable immediately and
contact an authorised dealer or service centre.
7. Do not try to remove the upper cover
Warning: Do not remove the cover of your NVR to avoid electric shock or damage to the electronics.
8. Handle with care
If your NVR does not work normally after dropping it or being hit by a hard object, disconnect the power
immediately and contact an authorised dealer or service centre.
9. Position the equipment in a place with good ventilation
The NVR system includes a HDD, which can produce a significant amount of heat during normal 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. Make sure your NVR is kept in a well ventilated area and that the cables are kept tidy and
do not obstruct air flow.
10. The included power supply can only be used for one NVR system, do not connect more equipment to the
power supply, it will not have enough power to operate correctly.
11. Do not place objects containing water, such as a flower vase, on or near the equipment.
