| Description |
|
A new powerful mobile phone signal jammer that will jam nearly all types of public mobile phones signal including the new 3G band.this model can be adjusted the signal frequency.so you can adjust the effective distance and range ( to 25M Radius), in order to only jam in a area which you need,and do not effect other area you do not need.it is more convenient than before.

VI.FAQ(Frequently asked questions) |
| |
6.1 While mobile phone signal isolator is in operation,why there is still signal indication on some mobile phones?
Reply：thisis only a feint.In fact,the mobile phones can not communicate at the moment.With a casual press on the dial keys,it will be found out that there is no signal indication at all.
6.2 Does the mobile phone signal isolator interfere with the normal operation of other electronic devices？
Reply:No,this is because the electromagnetic signal emitted by the isolator is completely in the range of the mobile phone frequency set by the state.It can only block off the communication of mobile phones.In addition,this kind of signal is always in acomparatively static state,it will not affect other electronic devices.
6.3 Does the mobile phone signal isolator do harm to human bodies and mobile phones?
Reply:Please set your heart at rest.The electromagnetic signal emitted by the isolator is very weak,it is shown by test data that such signal will not do harm to human bodies.At th same time,the mobile phone signal isolator will only block off the forwarding signals of mobile phones,make it unable to communicat with the base station,thus will not cause any damage to the
Mobile phone itself.
6.4 Is there any difference of operation range between indoor use and outdoor use?
Reply:Yes,the operation range usually refers to indoor range.When using th device ina wide outdoor space,the operation range can reach as long as hundreds of meters.It should be pointed out.Whenever using it indoor,the operation range has some thing to do with the conditions on the spot such as the distance from base station to the devic and the installation place etc. therefore, this point should be taken into account while using the isolator in order to avoid any dead corner which will affect its aperation.
6.5 Is the effect of the isolator on GSMphone andCDNA phone the same?
Reply: it is a good question,the anti-disturbance performance of CDMA phones is far better than GSMphones.However,there is not a great difference,only about 2-4 meters although the operation range of the isolator on CDMAphones is smaller than that on GSM.Yet,to ensure good effect on CDMA phones,user should increase the number of isolators indoors if necessary.
6.6 The housing of isolator gets hot after a period time of operation,does long time operation destrous the device?
Reply:thank you for your carefulness.this is a normal phenomenon.In fact,when designing,we take advantage of the heat conductivity of legging casing made of aluminum alloy to assist radiating for long time of stable operation.So,a hot casing will not damage the device.
