Why is the lock light (green light) of the mobile phone signal jammer not on?
There are many problems that are often encountered when installing the shield on site.
A wireless antenna is not tightened
If the whole body is tightened, the clinical symptoms are: some heart rhythms cannot be shielded. If this symptom occurs during the on-site security check, please first check whether the antenna is tightened.
.Key points for tightening the antenna: Since the antenna is made of two parts (1) the short connector; 2. the antenna pole), the lower part of the antenna connector needs to be tightened by hand during installation.
2 The wireless antenna is inserted incorrectly: Each product has a total of 4 wireless antennas, namely 800MHZ (China Unicom); 900MHZ (Mobile); 1800MHZ (Big Smartphone); 1900MHZ (Little Smart Phone). Each wireless antenna and The corresponding power sockets on the server must be consistent and cannot be plugged in incorrectly.
The best installation height is 1.7---1.8 meters long.
This distance is the height of the cell phone jammer from the floor. This spacing is best for shielding the house in the classroom.
Three power plug connectors have poor contact.
When connecting the power supply, be sure to find the corresponding demagnetization slot and do not force rough operation. In addition, if the switching power supply contact at the assembly site is poor, the problem is: the locking light (green light) of the cell phone signal jammer does not light up. To deal with poor contact on the on-site power plug: It is recommended to install a gasket on the switching power supply connector.
The four-switch power light does not light up:
This situation may occur for 3 reasons:
1. Poor contact of power plug
2 diode indicator light is broken
3. The power supply itself is broken. The criterion for identification is to see whether the green light of the power supply is on. If it is not on, the power supply itself is broken.
5. Some symptoms that the signal is not blocked may occur. The reasons may be as follows:
1Wireless antenna matching is incorrect
2The wireless antenna socket is not tightened
3. There is a signal displayed on the screen of the mobile phone, which is a false signal (this situation mainly occurs on Samsung and Tianyu mobile phones). In fact, the signal has been blocked.
4 is likely to cause signal jammer problems.
