1. In order to achieve the best receiving result, the unit is suggested to be far away from IR interfere sources, not to be straight to the fluorescent lamp, not to be used while several remote controls are working. If the receiving indicator lamp continues flashing, there must be serious interferes around, please adjust the receiver¡¯s position, or change operation environment.
2. Most notebook PCs have IR interfaces, which continue to produce IR signals to search the peripheral devices, and thus disturb the sampling unit. Therefor, when the unit is used with notebook PCs, the PCs¡¯ IR windows have to be shielded.
3. Non-38K short distance mode is recommended to use for high precise test.
4. Donot open the unit without our permission, otherwise we will refuse to repair and provide support. Post back to our company for repair if it is normally damaged.
