Signal jammer play a role in protecting symbols from interference. It can automatically pick up the frequency of symbols at a certain point of use, and play the role of defense symbols. Prevent some signal errors. After a period of use, we must strengthen its maintenance. To prolong its existence.

　　Dust and dust particles can be removed by wiping the signal blocker with a dry microfiber fabric. There is not much in the way of cleaning. It can be wiped up and down vertically or left and right. There is also a noteworthy microfiber fabric. If you find that the stain is still on your clothes, you can wet them with water, wring them dry until they are almost dry, then pull them a little and wipe the stain off from the top to the bottom. For stubborn spots, also recall spraying a small amount of ammonia and alcohol to loosen the cleaning product on the microfiber material and wiping the signal blocker. You can also wet the microfiber fabric with water and vinegar, but tighten the fabric to make sure no liquid drips from it, and gently wipe away the stains.

　　When cleaning protective signs, be careful to keep away from water.

　　When cleaning, do not get any more wet, in any other case it may prompt excess fluid to circulate the plug and may come into contact with the instrument's internal hardware. Some chemical cleaning products have the ability to corrode and damage the protective layer on the panel and must also be selected with care. Avoid cleaning products containing ammonia or alcohol.

　　cell phone jammer in the preservation process must be wiped clean in time, select the appropriate cleaning agent, do not use water, otherwise it will cause a fast loop. Be sure to show off when transferring, do not use now, in any other case, many indicators may be incorrectly shielded. Be sure to save it. Easy to use next time.

　　The so-called protection efficiency refers to whether there are blind spots or loopholes in shielding impact. In several prison areas, there may be transmitting base stations with strong cell phone signals. In order to obtain a very good shielding effect, it needs a lot of materials and electricity, and the cost will surge accordingly.

　　Therefore, the better the protection effect, the higher the cost can be. During the exercise, the protection requirements near the prison were usually better, with minor leaks and blind spots. Offenders can also seize on this loophole, allowing the phone to be used within the limits of its protection at start-up, while defending the phone's unique purpose cannot be accomplished.

　　Here are some things to remember when choosing:

　　In some activities where cell phones are not allowed to be used, if you take out your cell phone now, it will show that there is no signal on your cell phone. This is because the cell phone signal jammer is installed inside the occasion. With it, you can block mobile phone alerts.

　　Isolation Power: isolation power, compressive strength or look at the face of the voltage. It refers to the import and export, input and output, input and output and power supply between the withstand voltage. The higher the cost, the stronger the anti-voltage ability, the stronger the isolation function, the better the filtering performance. Through the anti-voltage detection of mobile phone signal jammer, this voltage-oriented test method is determined. When you look at it, between input and output, between input and output, between input and output energy, between output power, you get a frequency voltage of 50 hertz for a few minutes, in order to achieve the equipment and other capabilities between the goal of failure—voltage value.

　　When buying the gps blocker, you can refer to the above technical indicators to buy. We can test this to help us use it more correctly. To prevent the destructive effects of the signal. Make sure the instrument protects the mark well.

　　If the original fault-free provider lifestyles is 1 12 months, in actual use, the fault-loose carrier existence reaches 3 years, and the fee overall performance is tripled. If the authentic fault-loose provider life is 1-12 months, and the real use is much less than half of a yr, disasters regularly occur. Although it‘s far a unfastened warranty, the threat caused is immeasurable, and personnel resources also are wasted, and the corresponding cost overall performance is decreased.
