Audio and video matrix monitoring using precautions

1. The system is grounded. The system must have a perfect grounding. Otherwise, it will not only cause signal interference, instability, or mechanical damage, but also cause personal accidents due to leakage. The final grounding point of the AV switching matrix should be connected to true ground and its ground resistance should be less than one.

2. It is forbidden to change the original design. It is forbidden to modify or add any components to the mechanical and electrical design of this product. Otherwise, the manufacturer is not responsible for the hazardous results resulting therefrom.

3. Do not use a two-pin plug. Make sure that the input power to the device is 220V 50Hz AC.

4. There are AC 220V high-voltage parts inside the machine. Do not open the case without authorization so as to avoid the danger of electric shock.

5. Do not put the system equipment in a place that is too cold or too hot

6. The power supply of the equipment will heat up during operation. Therefore, it is necessary to keep the working environment well ventilated so as not to damage the machine due to excessive temperature.

7. Turn off the device power switch when it is rainy or wet or when it is not used for a long time.

8. Be sure to unplug the AC power cord from the AC outlet before the following operations: A. Remove or reinstall any parts of the equipment; B. Disconnect or reconnect any electrical plugs or other connections to the equipment.

9. Non-professionals without permission, please do not try to open the equipment chassis, do not repair it in order to avoid accidents or increase the damage of the equipment.

10. Do not spill any chemicals or liquids on or near the equipment.
