In different places and complex on-site conditions, in order to enable the backpack frequency jammer to play its role in interfering with the signal of the remote control detonation. To solve the problem of power supply for outdoor task equipment, the frequency jammer will be equipped with a built-in battery or an external battery box. Extend the use of jammers and protect warfighters from remote-controlled bombs. Whether the backpack frequency jammer uses a built-in battery or an external battery box, there is a lot of knowledge in maintaining the internal battery when it is idle and extending the service life of the battery. Let's discuss how to maintain the built-in battery or external battery box of the frequency jammer.
Regardless of whether the frequency jammer uses a built-in battery or an external battery box, the current mainstream batteries and battery boxes will choose the 18650 lithium battery as the basic battery cell. The 18650 battery cell has the characteristics of large capacity, sufficient power and long life. Correct maintenance of the battery can make the built-in battery of the frequency jammer play its best role and prolong the service life of the battery. Use the correct charger equipped with the frequency jammer to charge it. The batteries used by the frequency jammer are basically customized batteries, so the battery charger is also equipped separately according to the customized battery, so the charging of the built-in battery of the jammer should also be equipped with a special charger.
If the frequency jammer has not been used for a long time, the built-in battery of the jammer should also be charged and discharged once in a while. If the built-in battery of the backpack frequency jammer is not charged in time, the internal 18650 lithium battery cells may be damaged. If this occurs, after the battery is fully charged, the frequency jammer will find that the use time is shorter than the normal use time before. Not a lot. Then after shutting down and waiting for a period of time, then turning it on again, the frequency jammer can keep running for a period of time. At this time, it can basically be determined that the 18650 lithium battery cell of the frequency jammer is faulty and needs to be returned to the factory for repair.
To sum up, after using the frequency jammer, be sure to charge it in time to ensure that the battery is fully charged. In the case of no use for a long time, it should also be charged and discharged frequently to prolong the service life of the battery.
What does GSM cell phone mean: The common belief is that GSM is a network system. Currently China Mobile Unicom is GSM and China Telecom is CDMA. The Global System for Mobile Communications, commonly known as "Gotone", was developed in Europe for digital cellular network standards. It aims to enable global users to use mobile network standards and enable users to use mobile phones to travel the world. The GSM system includes GSM 900: 900 MHz, GSM 1800: 1800 MHz and GSM 1900 and 1900 MHz.
GSM cell phones use GSM cell phones. So far, mobile phones mainly include GSM, CDMA and 3G. So far, these phones are included in the first generation (1g) analog phones, in the GSM, TDMA and in the second generation phones. 3G cellular phone technology, 3G and third generation cellular technology.
