- 1. The antenna equipment is not tightened
If the antenna equipment is not tightened, the temporary phenomenon that occurs is that the occurrence of some frequencies cannot be blocked. If this symptom occurs during on-site installation, please first check whether the antenna equipment is tightened.
(1) Details of tightening the antenna: Since the antenna is composed of two parts of the activity (1 is the short connector; 2 is the antenna pole), you must hold the lower part of the antenna short connector tightly during installation. Tighten and screw on.
(2) Wrong antenna insertion: Each product currently has 4 wireless antennas, namely 800MHZ (China Unicom); 900MHZ (Mobile); 1800MHZ (Big Smartphone); 1900MHZ (Little Smart Phone) 4 types of wireless antennas, each antenna It must be consistent with the corresponding frequency socket on the server, and cannot be plugged in wrongly.
2. The best height-to-width ratio for installation is 1.7---1.8 meters long.
This distance is the height of the cell phone jammer from the ground. This distance has a better shielding effect in the classroom.

3. The power plug connector has poor contact.
When connecting the cell phone signal jammer to the power plug, be sure to find the matching slot and do not force rough operation. In addition, if the power supply contact is poor at the installation site, the symptom is: the indicator light (green light) of the mobile phone signal jammer does not light up. To solve the problem of poor contact of the power plug on site: it is recommended to add a gasket to the power supply connector.
4. The switch power light does not light up:
There may be three reasons for this situation:
(1) Poor contact of the power plug
(2) The diode indicator light is broken
(3) The power supply itself is broken. The criterion for identification is whether the green light of the power supply is on. If it is not on, the power supply itself is broken.
5. The signal jammer may not block some signals. The reasons may be as follows:
(1) Antenna matching is incorrect
(2) The antenna socket is not tightened
(3) The signal displayed on the screen of the mobile phone is a false signal (this phenomenon mainly occurs on Samsung and Tianyu mobile phones). In fact, the signal has been blocked.
(4) There may be a problem with your own signal blocker. - Andando gente
