【Precautions for use】
■ The antennas included with the 2G / 3G / 4G jammers are individually designed for each carrier, so please be careful not to make mistakes when removing and reinstalling. Effectiveness may be significantly reduced or malfunction may result.
■ The base structure of each antenna is weak, so handle it carefully so as not to put a load on this part.
■ The effective range may be narrowed depending on the usage environment. Also, depending on the make and model of the phone, there may be differences in sensitivity, inefficiencies, or it may take time to stop service.
■ If the mobile phone and the base station are close to each other, the original effect may not be produced due to the strong radio waves.
■ Do not use it for prank or harassment purposes.
■ Please use this product in accordance with domestic radio laws.
