Things you don’t know about mobile phone signal jammers
Effectively signal jammers various walkie-talkie signals, blocks (interferes with) the communication between the walkie-talkie and the receiver, and prevents various wireless stealth headsets (including anti-shielding and anti-detection headsets) grafted to the walkie-talkie system from working properly (strong noise or no sound) )
It only blocks the intercom signal and does not affect the normal operation of other electronic equipment.
Environmental protection, the amount of electromagnetic radiation has been strictly tested by the Environmental and Health Related Product Safety Research Institute of the Chinese Center for Disease Control and Prevention. The measured values of electromagnetic field intensity at each sampling point are far lower than the "Electromagnetic Radiation Protection Regulations" (GB8702-88) and are not harmful to the human body. Influence.
Low power consumption, it only blocks the intercom or receiving signals in the examination room, and does not interfere with the built-in switching power supply of intercom outside the examination room, ensuring the stability and accuracy of the signal.
The operation is simple, the antenna is installed correctly, and it operates automatically when it is turned on.
Technical indicators:
Effective shielding range: 20 meters (the emitting 5W walkie-talkie is 100 meters away from the examination room)
The smaller the power of the intercom and the further away from the examination room, the greater the shielding range.
Transmission frequency range: full frequency band.
Transmitting power: 3W.
Ambient temperature:-20-+55℃..
Relative humidity:35-85%
Power adapter: input AC160-240V50/60Hz.
Body size: 210mm*139mm*50mm.
Net weight: 1Kg.
