Operating Instructions of mobile phone jammer (GL-07)

GL-07 jammer is the first one that can block satellite phone signal. Not only block CDMA, GSM, 3G. And the jammer can exten jamming function based on the current jamming frequency. GS-07 provide comprehensive functions and take use of high power IC and power supply. The GS-07 jammer can live 2 times of the jammers of our competitors. You can hang the jammer on the wall or pur it on the desk. Easy to use, after pluged in, it can start working, and does not need maintenance. When use the jammer, only need to connect the antenals to the corresponding hole of the host. Please notice that do not mistake the antenals. The numbers marked on the antenals must be the same with the number marked on the hole of the host. Make sure that the two numbers are the same, then the mobile phone jammer can start to work.

(1).Take the mobile phone jammer host out of the packing, and check that the host and all accessories are in the packing. Please read the instructions first before you use the mobile phone jammer for the first time.

(2).Plug the antenals to the right hole, the number marked on the antenal must be the same with the number marked on the hole of the host. And tighten the antenals

(3).Plug the male plug of the jammer to the socket.

(4).Switch on the power supply. Before switching on, do make sure that the antenals are tightened.

(5).When the light of the host is red, the jammer is working well. About 10 seconds later, can jam effectively. ( attention: Please tighten the antenals and screws. If the antenals are pluged in wrong holes will lead to damage the host and can not block mobile phone signal )

(6).Hang the mobile phone jammer on the wall, the best hight to install the jammer is about 2 meters

(7).The different installation location in the space of different sizes.

(8).In small space, install the jammer in the center, scinece the jamming coverage is a round area with the jammer as a center.

(9).In big space, please install the jammers with celluar mode. And turn the antennals to the direction which you want to block mobile phone signal.

• Considerations of installing mobile phone jammer:

(1). To get the best jamming effect, installing places to install the jammers should be farther than 200 meters from the cellular station. If the distance is less than 200 meters, the jamming coverage can also become less, depending on the signal of the location.

(2). Jamming coverage indicated in the instructions is based on the filed intensity of minus 70dB. If the filed intensity is higher than minus 70dB, the jamming coverage will become less. You can turn the antenals to the direction which you want to block mobile phone signal.

(3). Before install the jammers, please make sure that the antanals are installed in right holes of the host- the number marked on the antanal is the same with the number marked on the hole.

(4). Before install the jammer, please prevent that metallic things within 0.5 meter to reflect the signals. This will affect the jamming effect.

(5). Before install the jammers, please find out the locations of the cellular stations first. And install the jammers between the cellular station and the place you want to block mobile phone signal.

(6). If install the jammers on the wall, the best hight is about 2 meters.

(7). Different ways to install jammers in different spaces:

A. Installed the jammers in the center of small spaces, the jamming coverage is a round area with the jammer as the center.

B. Install the jammers by cellular mode in big space, and should turn the antanas to the direction which you want to block mobile phone signal.

8. Considerations of installing mobile phone jammers.

(1). Distance from the place that you want to install jammers to the cellular station should be farther from 200 meters. If the distance is less than 200 meters, the jamming area will become less. Jamming area depending on the signal strength of the location.

(2). Jammimg coverage indicated in instructions is base on the field intensity of minus 70dB, if the field intensity is higher than minus 70dB, the jamming coverage will become less. You can turn the antenas to the direction that you want to block satellite phone signal.

(3). Before install the jammers, please make sure that antennas are installed in right holes. The number marked on the antenals is the same with the number marked on the hole.

(4). Before install the jammers, please prevent any metallic things to reflect the signals, the things will affect the jamming effect.

(5). Please find the locations of the cellular stations. Install the jammers between the cellular station and the place you want to block mobile phone signal.

(6). If there are windos in the room in two sides or four sides. Please first measure the filed intensity, install the jammer at one end that mobile phone signal is stronger.Usually the window side has stronger signal. But if there is still dead corner, please install another jammer on the other end.

(7).When install mobile phone jammer in the open air, if install omni antenna, take the central point of the jamming area as the installation point. If take directional antenna, the installation point is one end of the jamming area, the antenna should point to the jamming area.

(8). If install the jammers on the wall, the best hight is 1.5 meters or 2 meters. The antennas should be vertical with the ground to get the best effect.

(9). If install the jammers on the ceiling, the antennas should be vertical with the ground to get the best effect.

Application Notice

• First install the antennas, then plug the power supply.
• Since the valid scope covered by the isolator is a round area with the jammer as the center, you should pay attention to choosing the correct place where the deviece is located so as to avoid the dead corner.

3. The device should be placed in the areas of good ventilation. Please try to avoid the shielding of big objects, or keep away strong electromagnetic sources with heat sources to ensure high isolation effect and stable operation for a long time.

4. Do not put other objects on the isolator or dismantle antenna while the device is working. Otherwise, the isolation effectiveness will be tampered with or the device will be damaged.

5. While using the isolator outdoors, be sure to keep it away from water or damp.

6. Switch off the device in time when not using it, lest the normal operation of mobile phones be affected.

7. When the application area is larger than the covering scope of the device, it is recommended to use several isolators and install them by cellular mode.Installation Notice:

Please consider the following factors based on installation technology:

Overall factors when installed in doors:

1. Consider the application area.

2. Consider the height from the ground to the room.

3. Consider that if there is signal enhancement or second-level amplification in the room.

4. Consider the jamming effect of the decoration materials building materials.

5. Consider the proportion of metal and nonmetal.

6. Consider the wireless devices in the room, the transmitting frequency of these devices may cause co-channel interference.

7.Consider the different frequency generated by precision instrument in the room. And the safety distance of the precision instrument.

8. Consider the positions and orientations of the door and windows.

Overall factors when installed our doors:

1. Please consider the following factors if install the jammers outside doors.

1). The influence to the jammer when cellular station transmitelectromagetic waves in lateral and longitudinal.

2). If the distance from the cellular station to the jammer is too small, the jammer may affect the cellular station.

3). The walls that influenced the electromagnetic wave of the jammer.

4). The obstacles that influenced the electromagnetic wave of the jammer.

2. Factors when installed in special areas

1). Measure the field intensity of this area.

2). According to field intensity and site topography to get a probable installation scheme.

3. Maintainance

1). The jammer does not need

2). When wipe the jammer, please do not use chemical solvent, do not drop water into the inside jammer. Put the jammers in dry an wntilated places. And avoid smoke and toxic gas.
