Precautions for Using a Cell Phone Signal Jammer
1. The effective shielding range of a cell phone signal blocker will vary depending on the location. This is closely related to the signal strength at the location. Different cell phone models may not necessarily have the same shielding range at the same location.
2. Factors affecting the shielding range include, but are not limited to, distance from the base station, orientation, presence of obstructions, building material, mounting height, and installation specifications.
3. Each antenna has a frequency band identifier, which must correspond to the frequency band identifier on the main unit. Before turning on the jammer, ensure that each antenna is securely connected. Never operate the jammer without an antenna connected.
4. After extended operation, the surface temperature of the jammer will reach approximately 40-50°C. This is normal. If the surface temperature is excessively high, turn off the power and contact TopSignalJammer after-sales service or your local distributor.
5. The normal mounting height of the signal jammer is 1.8-2.5 meters. Try to install it in a location with no obstructions between it and the target shielding area. When wall-mounted, the antenna should face vertically upward. When used on a desktop, the antenna can be bent 90 degrees and pointed vertically upward. No AC power lines or other audio or video lines should be within 0.2 meters of the antenna.
6. During use, to avoid potential interference with other electronic devices, keep the antenna at least 1-2 meters away from common devices such as speakers, wireless microphones, radios, computers, televisions, and Wi-Fi routers.
