The military china cell phone jammer for military purpose

Then if the phone's antenna performance is poor, even more will be worse.
To protect the phone's battery. In general, mobile phone batteries meet the temperature 10 ℃ -40 ℃, preferably within the temperature range used, too hot or cold environment is not conducive to cell phone batteries to play the greatest efficiency, will not achieve the longest call or standby time.The accessory of  cell phone jammer contains the manual, 4 pieces of antennae and the power adapter.
Ensure the smooth transmission of signals, some mobile phone users, the call can easily hold the antenna in the hands, so call, conscious as possible to stay out of the antenna distance of 2-3 cm, to ensure that the signal smooth transfer and reduce the phone's power consumption.
Optimal power-saving mode digital phone calls. It is the military  china  cell phone jammer for military purpose. Most models are equipped with digital mobile phone DTX non-continuous emission advanced power saving mode function, for power, do not call when the phone is in a temporary state, it can reduce the power of radio waves transmitted by the phone. Observed that, DTX power-saving mode, extend the talk time of up to 30% -50%.
Note maintenance of the battery to extend its life. Mobile phone is easy to produce nickel-cadmium battery "memory effect." Prevention is the emergence of low-voltage warning or when the phone is turned off automatically when battery is fully discharged and then to wait to charge, and in accordance with the requirements of different models, to ensure sufficient charging time, you can prevent the battery have a "memory effect."It is the multi-purpose convertible EOD convoy jamming system bomb   cell phone jammer . In addition, the mobile phone with the power on to the battery completely discharge and then fully charge, repeated more than three times, "memory effect" can be eliminated.
Mobile users should be prepared with a few large battery backup. Some mobile users prefer to prepare a few other panels, although they may be a pressing problem, but when you buy additional panels to guard against fooled. Counterfeit mobile phone batteries on the phone board is very damaging, then how can we identify a cell phone battery plate is true then? There are several ways to introduce you to:
To see identification: identify the real battery panel printing is very clear, and the printing of counterfeit product is remake of the plate, illegible. It is 200W military UHF  cell phone jammer .True solar panels "±" symbol polarity done directly in the metal contacts on the fake plastic shell to do the above, and some did not "±" sign.

Look at technology: the use of ultrasonic welding is really panels, front and back covers can not be separated, no obvious cracks. The fake panels are mostly handmade, glued, will be a little hard to exclude two and a half.

Look at safety performance: regular mobile phone panels to protect the batteries and mobile phones are equipped with temperature control switch, if the charging time is too long, the voltage is too high, sharp rise in temperature, solar panels will be time to cut off power when hot, to prevent battery leakage or explosion.The UHF/VHF immobilizer is another kind of  cell phone jammer .
The inferior panels, no this device, but electric soldering iron, and even the camera-specific small non-rechargeable batteries together, and counterfeit lithium batteries, such as the forced charging, may cause an explosion.
