Frequently Asked Questions (FAQs)
How does a signal jammer work?
Signal jammers block mobile phones by transmitting interference signals on the same frequency bands, preventing normal communication with cell towers. Our device uses intelligent scanning technology to target only specific frequency bands, ensuring other electronic devices remain unaffected.
What is the effective range of the jammer?
Blocking range depends on multiple factors, including power level, signal strength, and operating environment. Typically, handheld devices cover 5–15 meters, desktop devices cover 10–30 meters, and high-power devices reach 50+ meters. We'll recommend the right product for your specific use case.
How to properly install and use a signal jammer?
1. Place the device at the center of the area to be shielded. 2. Ensure a stable power connection. 3. After turning on the device, wait 1-2 minutes for optimal performance. 4. Adjust the power level as needed. For detailed instructions, refer to the product manual.
Does the device need to be on for 24 hours?
Recommend based on actual usage scenarios. For venues with scheduled use such as exam halls and conference rooms, enable only when needed; for facilities like prisons and secure rooms, keep running 24 hours per day. The device is designed to support long-term continuous operation.
How do I maintain and care for the device?
1. Regularly clean dust from the device surface. 2. Ensure proper ventilation to prevent overheating. 3. Check that power cords and cables are in good condition. 4. Schedule a professional inspection every six months. Under normal use, the device lifespan is 5–8 years.
Is using a signal jammer legal?
Restricted to specific institutions only, such as educational authorities (school exam centers), judicial bodies (courts, prisons, border control), and military or classified facilities. Individual purchase or use is strictly prohibited. The system must be registered in advance with the local public security department and radio management authority before activation.
