Precautions:

1. Factors affecting the actual shielding range include signal field strength, base station distance, mobile phone format, obstacles, installation height, installation specifications, etc.
2. It is normal for the host to heat up after working for a long time. If the temperature is too high, please turn off the power and contact your local dealer
3. The normal installation height is 1.8m～2.5m, try to choose the place where there is no obstacle between the target shielding area. The wall-mounted installation requires the antenna to be vertically upward. When using on a desktop, the antenna can be folded 90 degrees and then vertically upward. There should be no AC power lines or other audio and video lines within 0.2 meters of the antenna.
4. In order to avoid possible interference with some electronic equipment, please try to keep 1~2 meters above the following common equipment: audio, wireless microphone, radio, computer, TV, Wi-Fi router, Rcied, etc.
