One: Summary
With the high-speed development of communication technology in the information times, mobile phone has become indispensable tool in daily work and life of people. But the wide use of mobile phone has also brought some un-neglected problems. Mainly as following:
1. 1 It becomes a new secret leak channel and brings danger to secrecy information.
With the development of science and technology, the orientation, track and scrutiny to mobile phone have become the most important recon measure and source of information. So taking a mobile phone in a privacy price, whether using mobile phone or not, if only opened, it will leak out secret and bring serious danger to enterprise, personal, even to Party and country.
1. 2 It becomes a new source of noise and brings trouble to natural working system.
The increasing prevalence of mobile phone make the environment of meeting room, court, library and school deteriorated. The sound from mobile phone damage the quiet and grave atmosphere of these places and make bad impact on the operation of daily work.
1. 3 It becomes a new unsafe factor and brings bad impact on the safety of enterprise.
There will be fire or explode when using mobile phone in gas station, oil field or store and the result will be very serious.
1. 4 It becomes a new commit measure and brings bad impact on the safety of society.
Some gambled people make use of mobile phone to cheat in the exam, some terrorist and hostile even use mobile phone to bomb.
Our company has developed mobile phone signal isolator that can solve all the problems above. As a new style of information safety product, using a special electromagnetic signal, forming a electricity network in a protected place, then the mobile phone can’t receive the basic data and establish connection with the basic station and eliminates the bad impact brought by mobile phone, and functions as protection.

Four: Instruction for fixing and use
4.1 Process and Measures for Fixing
4.1.1 Take out the mainframe of screen from packing box:
4.1.2 Revolve the antenna into respective antenna seat or it will be unavailable.
4.1.3 Put up the isolator on the wall or a correspondent position, the best height must be 1-1.8 meters.
4.1.4 First, connect the 5v output of the power supply to the mainframe, second, insert the indirect current input into the electrical outlet and then start the switch of power supply, the shine of indication light shows working.
4.1.5 As to measures of big or small space for fixing to get point are as the following chart:
Example one: small space of room (less than 200 square meter)
Example two: big space of room (more than 200 square meter, several sets should be adopted)
Example three: big space outside room (more than 1000 square meter, more effective to use several sets)
4.2 Notice
4.2.1 The antenna must be fixed properly first, according to the correspondent sign, and then electrify the power supply of mainframe.
4.2.2 The effective covered range is a round area, considering the isolator as the center, so the position of isolator must be chosen correctly in order to avoid a dead corner of isolation.
4.2.3 The isolator should be put in a good place where wind can come to avoid shield by big object, avoid strong electromagnetic source of strong hear source, to guarantee the effect of isolation and stable work.
4.2.4 Don’t put other goods on the isolator or knock down the antenna when it is working, in order not to affect the isolation effect or damage the machine.
4.2.5 Cut off the power supply in time, in order not to be affected, when the isolator is not in use.
4.2.6 Avoid water when used outside.
4.2.7 When the useful field range is bigger than the available isolator, it is better to adopt several sets of isolator for fixing to guarantee a good isolation effect.
4.2.8 Because the power supply and antenna is used together with the mainframe, also debugging after leave factory is one to one, so please don’t use in exchange with each other to guarantee the best effect.
4.2.9 Please far away from causticity gas and liquid, and make good preparation to avoid dust and humidity, in order not speed aging of parts inside the equipment.

5.3 When using, put it in a dry and windy place, and avoid to contact fog and poisonous gas
5.4 The period for repairing is one year, repairing for free among three years, and repair for the whole life.
Six: Solution for problems
Why some mobile phone signal indication still has signal indication when the mobile phone isolator is working?
Answer: This is only a feint, in fact, the mobile can’t communicate at this time. When pressing any button, you will discover that there is no signal indication on the signal indicator.
Does the mobile phone isolator disturb the ordinary performance of any other electric equipment?
Answer: No. Because the electromagnetic signal from the mobile phone isolator is completely located in the frequency strip stipulated by the country, only block the communication of mobile, and this kind of signal is in the state of stillness, it won’t bring bad impact on any electric equipment.
Does the mobile phone isolator have bad impact on people and mobile phone/
Answer: Please be sure that the intension of electromagnetic signal from the mobile phone isolator is very weak, according to the tested data, this signal intension doesn’t damage people. At the same time, it only block the signal below to make the mobile phone unable to get in touch with the base station, so it won’t damage the mobile phone itself.
Is there any difference of distance between inside and outside?
Answer: Yes. The effective distance of mobile phone isolator (30-40 meters) generally means distance inside the room. It will reach to several hundred meters when using outside. It should be pointed that whether using inside or outside, the effective distance of the isolator is according to the environment of that time, such as the distance, position and so on. So this factor must be thought when using the mobile phone isolator to avoid the dead corner that will affect the shield effect.
Does the mobile phone isolator do the same effect to GSM mobile phone and CDMA mobile phone?
Answer: This is a good problem. Because the capability of anti-disturb of the CDMA mobile is better than GSM, so it effective shield distance to CDMA is less than GSM mobile phone. But there is not much difference, about 2-4 meters. But it warns to users that in some important places, if necessary, the quantity of mobile phone signal isolator should be increased to make sure of the effect to CDMA mobile phone.
The shell will become warm in a short time, so will it damage the mobile phone when used for a long time?
Answer: Thank you for your carefulness. This is an ordinary phenomenon. In design, we just make use of the aluminum metal shell to emit heat, so to guarantee a stable work a long time. So it won’t damage the mobile phone when it becomes warm.
