Being familiar for use immediately
      Now let us introduce this portable signal jammer to you and make you better understand about the
positions of all the buttons as well as operational ways

Why to choose the Desk Signal Jammer
 1. We designed this device with highly efficient power adjustable functions for all
the frequency channels. The output power and shielding range can be regulated by
turning the button on the device. Moreover, you can close any channels separately
without affecting the other channels.
2. This Device is provided with a wireless remote controller. The operator can
ON/OFF the machine at any time in any direction. It can jam GPS and wifi too.
3. This Device is mainly used for AC current. We will provide different power
adaptors available for different countries. Therefore, it can be used globally.
4. Presently we provide the device with 5V 10A power adaptor. With enough power
to make the jammer nonstop work 365 days/24H, this adaptor can also maintain the
stable working of the device
5. with high heat dissipation technique and designed with two fans to keep the heat
dissipated, the device can work for a long time without so much heat and always in
a good working status.

How to install Antenna and turn on the Device
To install the antennas, please try to screw the antennas tightly to the corresponding position on
the device according to the length remark on the device and antennas
The antenna connectors of Output power and working indicated LED on the device. connect with antenna
which are identified by GSM,DCS,GPS and 3G as the indication accordantly, will be ON when the Power
SW placed, Power LED shows green, then the machine begins to work.
Fixed brackets and heat sink chip
We provide the device with brackets .You can choose to mount the machine on the wall. The heat sink

chip, designed with Aluminum materials, can make the jammer with a better heat dissipation and work

highly efficiently.

To start the device
It is easy to operate .Once the machine is turned on, you can adjust the output power by your fingers.

Please see the followed ones. We also provide the machine with a remote controller .The operator can

choose the manual operation or remote control through the key on the remote controller.

45 ℃, it is abnormal. Please put the power SW to OFF immediately and try to contact your local distributor

or agent.

2) The shielding range of the device will be determined by the local signal strength. In different situation, it

will be with different performance.
