10. Use attention

1) Store and use in an environment without any external pressure and affecting quality;
2) Store and use in an environment free of polluting gases or sea breeze (salinity);
3) Store and use in a low humidity environment;
4) Solder the lead pins under the specified conditions. After soldering, do not apply external force;
5) Please do not clean this product. Before use, please connect the operator and the soldering iron to the floor wire with an electrostatic belt;.
6) Please pay attention to protect the receiving surface of the infrared receiver. Contamination or wear will affect the receiving effect. At the same time, do not touch the surface.
