The hole at the bottom of installation box of cell phone jammer

The installation box of  cell phone jammer  is with shutter-type ventilation positions at two sides.
The method can be used to determine the point of failure in the battery or in part of the circuit. The specific method is: first battery is fully charged, then the batteries on a false load power supply current is controlled at about 300mA, time for about 5 minutes. If the battery is normal, then the terminal voltage should not drop. More rigorous methods to measure the capacity of the battery, but more time-consuming. Note: According to the nominal voltage of the battery, the dummy load is available 3V, 4.5V, 6V bulb or external series resistance of a power. Measurement line connected to the battery reed only by mechanical crimping and not welded, so as not to damage the battery or accident. The law is a kind of emergency in the home appliance repair. The hole at the bottom of installation box of  cell phone jammer  can prevent from water accumulation.
Its precondition is not a major impact on the whole electrical indicators, and not endanger the safety of equipment (such as: switching power supply jumpers maintenance). For the maintenance of mobile phones, available thin high strength enameled wire (Φ0.1) jumper 0Ω resistor or a unit, with the 100pF capacitor connected across RF or IFSAW filter. Most GSM mobile phone with a certain degree of self-test and fault diagnosis function, which is helpful for rapid fault location to a particular unit. In using the law to require that the phone starts up normally, but the maintenance must also know how to enter the diagnostic mode. The latter requirement needs related to mobile phone repair service at hand.  cell phone jammer  will adopt outdoor installation.
Overview of products and companies. August 16, 2011, millet phone was officially released, domestic media for the first time come into contact with this so-called "China's mobile phone enthusiasts to create" smart phones. Dual-core 1.5GHz, 1GB of RAM, 4GB ROM, 1930mAh lithium battery, the Android 2.3.5 system and engineering Commemorative Edition 1699 yuan, 1999 yuan, the retail version, these parameters again and again to refresh the existing smart phone hardware standards, but also the day of conference time to a climax. The millet mobile phone the most attention is the hardware configuration and price, the phone again to refresh our minds of the hardware the height of the domestic and even world's most powerful dual-core Android phone, millet. The lightning protection measure of  cell phone jammer  is actually adding the lightning rod to  cell phone jammer .
Millet phones using the Qualcomm MSM8260 1.5GHz dual-core processor, similar to the HTC G14, the CPU, but a higher frequency. Terms of memory with 1GB RAM and 4GB of ROM, and fully meet the needs of the application. The screen used in Sharp's 4-inch screen, the material is estimated ASV, a 16:9 854x480 resolution, namely FWVGA. This screen uses a transflective reflector structure, sunlight can also be clearly seen. The camera is 8 million pixels. Millet (full name of Beijing millet limited liability company) set up by former Google, Microsoft, Jinshan, the company's top players, is a company focused on the new generation of iPhone, Android and other smartphone software development and hot mobile Internet business operations. The lightning rod has to be used for  cell phone jammer .
