1. Poor interference effect
1.1 Insufficient signal coverage
Troubleshooting steps:
Check antenna connection: Make sure all antennas are firmly connected and not loose or damaged.
Check antenna position: Make sure the antenna is correctly located in the center or a reasonable position of the target area.
Adjust antenna angle and height: Adjust the angle and height of the antenna as needed to optimize signal coverage.
Increase transmission power: If the cell phone jammer allows power adjustment, you can try to increase the transmission power to improve signal coverage.
Increase the number of antennas: For large areas, you can increase the number of antennas to ensure that all areas are covered by the interference signal.
1.2 Incorrect frequency setting
Troubleshooting steps:
Check frequency setting: Make sure the frequency setting of the cell jammer covers all target frequency bands, including 2G, 3G, 4G and 5G.
Update frequency setting: Update or adjust the frequency setting according to the actual situation to ensure the interference effect.
Use spectrum analyzer: Use a spectrum analyzer to check the signal frequency bands in the surrounding environment and ensure that the cell jammer covers all frequency bands that need to be interfered.
2. The cell jammer cannot start
2.1 Power supply problem
Troubleshooting steps:
Check the power connection: Make sure the power cord is firmly connected and not loose or broken.
Check the power switch: Make sure the power switch is on.
Check the power adapter: Make sure the power adapter is working properly. You can use a multimeter to measure whether the voltage output is normal.
Replace the power adapter: If the power adapter is damaged, try replacing the adapter.
2.2 Internal circuit failure
Troubleshooting steps:
Check the internal connection: If you have relevant technical knowledge, you can open the device to check the internal circuit connection and make sure all connections are firm.
Check the circuit board: Use a multimeter to check the key components on the circuit board, such as capacitors, resistors, etc., to ensure that there are no damaged or burned components.
Contact the manufacturer for repair: If you cannot troubleshoot or repair the internal fault by yourself, you can contact the manufacturer or professional maintenance personnel for inspection.
3. The interference signal is unstable
3.1 Environmental interference
Troubleshooting steps:
Check the surrounding environment: Make sure there are no strong electromagnetic interference sources around the cell jammer, such as large electrical appliances, radio equipment, etc.
Adjust the cell jammer position: If possible, try to adjust the cell jammer position away from the interference source.
Use shielding materials: Use shielding materials such as metal mesh or shielding cloth around the cell jammer to reduce environmental interference.
3.2 cell jammer failure
Troubleshooting steps:
Check the antenna connection: Make sure the antenna connection is secure and not loose or damaged.
Check the cooling system: Make sure the cell jammer's cooling system is working properly and not overheating. Clean the dust on the cooling holes or fans to ensure good ventilation.
Check internal components: Use a multimeter to detect internal components to ensure that all components are working properly. If damaged components are found, replace them in time.
4. The interference range is too large or too small
4.1 Adjust the transmission power
Troubleshooting steps:
Check the power setting: Make sure the power setting of the cell jammer is correct and suitable for the size of the target area.
Adjust the transmission power: Adjust the transmission power of the cell jammer according to actual needs. Reducing the power can reduce the interference range, and increasing the power can expand the interference range.
4.2 Adjust the antenna direction and angle
Troubleshooting steps:
Check the antenna direction: Make sure the antenna is pointing to the correct target area.
Adjust the antenna angle: Adjust the antenna angle as needed to optimize the signal coverage.
5. The cell jammer is noisy
5.1 Fan noise
Troubleshooting steps:
Cleaning the fan: Clean the fan inside and outside the cell jammer to remove dust and debris.
Check the fan bearing: Make sure the fan bearing is well lubricated and not worn or damaged.
Replace the fan: If the fan is damaged or the noise is too loud, try replacing the fan.
5.2 Electromagnetic noise
Troubleshooting steps:
Check the shielding measures: Make sure the shielding measures of the cell jammer's internal circuit and external shell are effective to reduce electromagnetic radiation.
Adjust the position: Try to place the cell jammer farther away from sensitive equipment to reduce the impact of electromagnetic noise.
The telephone signal cell jammer may encounter some common faults during use, such as poor interference effect, failure to start, unstable signal, too large or too small interference range, and loud working noise. Through reasonable troubleshooting and adjustment, these problems can be effectively solved to ensure the normal operation and optimal effect of the cell jammer.
