Product Introduction This device is a new integrated signal jammer. It can efficiently shield only the reception of effective signals without any impact on surrounding operators' base stations. Designed with built-in high-gain antenna coverage, it can shield various signals such as dual-mode 2G, 3G, 4G, 5G, GPS, and WIFI from operators within a shielding range of 5-10 meters (depending on the strength of base station signals), completely cutting off all communications within the shielding range from the outside world.
As the current signal coverage continues to strengthen, resulting in poor shielding effect of jammers, this device has been proven through multiple experiments to achieve the optimal shielding distance. We adopt imported chips to improve efficiency and high-gain built-in antennas to enhance coverage power. It is applicable in occasions such as conference rooms, classrooms, prisons, and confidential areas.
(1) If the power indicator does not light up when the device is turned on: Check the power connection cable. The internal battery may be dead or the power indicator may be damaged. (2) If the power indicator flashes when the device is turned on: There may be a motherboard fault or an internal motherboard malfunction. (3) If the fan does not work when the device is turned on: Check the switch and power indicator. If the fan is faulty, it needs to be replaced.
Short shielding distance or no effect: (1) Check whether the power plug is connected to the mains; check whether the main power switch is turned on. (2) Check the device for abnormal noise. Pick up the device and shake it left and right to listen for any abnormal sounds. If a clear abnormal noise is heard, it is initially judged that some internal components of the device have fallen off. (3) If the device is relatively close to the operator's transmitting base station tower and the signal field strength is -50dBM, the shielding distance of the device will be short.
II. Precautions
Please keep electronic products away from water.
The power supply of the device shall be in accordance with regulations, and the recommended operating voltage is AC220V. Before installation, ensure that the user's power supply system is within this range. Exceeding the maximum voltage of the device will cause damage to the device.
The product is equipped with a power-on protection circuit, and there will be an interval of 1-2 seconds after the power switch is turned on.
When the ambient temperature exceeds the normal operating temperature range, it is recommended to cut off the power.
In case of abnormal situations, do not attempt to repair the device by yourself. The manufacturer shall not be liable for damages caused by built-in high-voltage original accessories or disconnecting the connections between components.
Product Installation and Operation Process
Equipment Installation (1) Check the Equipment Inspect whether the appearance of the equipment is in good condition and whether the relevant accessories are complete.
(2) Equipment Installation
Determine the installation location:
Installation: For temporary use, the main unit can be placed on the tabletop; for fixed use, it can be mounted on the wall. The installation position 180-250 cm above the ground is recommended for better performance.
Equipment Usage The operation of this machine is controlled by the power supply. Connect the power supply, manually turn on the power switch; the device will start and operate. Turn off the power switch, and the device will stop working.
1 - Power cord: Used to connect the device to the power source and supply power to the device. 2 - Main power switch: Used to control the overall power on/off of the device. 3 - Power indicator light: Used to display the power status of the device. Usually, when the light is on, it indicates that the device is powered on. 4 - Remote control switch: The device can be turned on or off through a remote control, which is convenient for users to control the device from a distance.
