Several cell phone jammers can be installed

5. Installation and notes of cell phone jammer

The cell phone jammer can be directly fixed on the wall or ceiling with the screw. The surface temperature of the product can reach 50℃; therefore keep it away from the object of the low heat-resistant performance. Installation height: the installation height of the series of BH-201 mobile phone jammer is 1.8-2m and at this time the biggest isolating range can be achieved. Installation direction: don’t point the antenna of the series of BH-201 cell phone jammer to the base station direction of the cell phone; otherwise the effect will be influenced.

5.1 Antenna connection of cell phone jammer

The antenna adopts the error-proofing design and it can be inserted and connected well only when correct.

If switching on the power supply when the antenna isn’t installed, the machine may be damaged.

5.2 Power supply connection of cell phone jammer

Check the power supply switch of the main machine and confirm the power supply switch is in the off position. Insert the output plug of the power supply transformer into the power supply socket in the middle at the left side of the main machine. The input plug of the power supply transformer connects with AC220V power supply.

6 Instructions of cell phone jammer

6.1 Isolating the cell phone signal: turn on the power supply switch of the main machine after confirming the antenna connects with the power supply; the power supply indication light is on; after 30s, the cell phone will display no signal or no network.

6.2 Cancel isolating the cell phone signal

If blocking of the cell phone signal is not needed, turn off the power supply switch.

6.3 Adjust isolating range

Normally, the emission power has been adjusted before delivery so there is no need for the user to adjust after purchasing.

The cell phone signal blocking range, installation position and height, antenna direction, distance from the base station, buildings around and so on can be selected through the test. The appropriate installation position and height and antenna direction can be determined to meet the needed isolating range. If the needed isolating range is large, several cell phone jammers can be installed; if the isolating range of the single cell phone jammer is larger than the needed isolating range, it can be realized by adjusting the emission power of the machine.
