Only block mobile phone signals, does not affect the normal operation of other electronic devices
Within the examination room only shielded cell phone signal, no interference on the phone outside the examination room, nor will it interfere with the base station
Shielding only the base station transmit frequency without affecting the uplink downlink frequency
Green, the electromagnetic field intensity is far below national standards, without any impact on the human body
Simple, properly installed antenna, power supply can be run automatically
Industrial grade power supply, all stainless steel body heat, can be super long hours
Soft-start circuit design to effectively avoid the phenomenon appears when the ignition
Selection of Hitachi High-performance integrated circuits, 902M VCO and chip components, imported automatic placement machine and reflow machine processing, assembly line production, quality, performance and stability, not more than 2% repair rate. cell phone jammer could be used in public security.
CM-808P mobile phone jammer (explosion proof)
CM-808P mobile phone signal jammers mainly foreign advanced technology, mainly for the national college entrance examination for adult college entrance examination, self-examination and various universities in the examination process,
the phone can not play and the answer, but and does not interfere with other electronic teaching equipment work, leave the phone off the range, you can resume normal use. Also a clean school, a Ning also meeting the net.
This mutation of the radiation signal, the light interference of precision instruments and equipment around the work, such as in hospitals, will affect pacemakers, ECG recorders, and other similar sophisticated equipment, leading doctors to diagnose errors. In severe cases, cause a static spark, ignition of combustible gases, the gas station, filling stations, chemical storage, oil refineries, hazardous materials storage yards and other areas of significant security threat. And people have adjusted the  cell phone jammer  set already.The cell phone signal jammers can be formed in a specified position within the magnetic shield (ie the mobile phone can not receive this signal), the mobile phone (including China Telecom, China Unicom and various PHS) within the specified range can not be played and access, will not be able to form the radiation signal mutation, so as to achieve the purpose of mandatory disabled mobile phone, the security of the above sites offer great protection.
Features:
Effective shielding CDMA (China Unicom), GSM (China Mobile, China Unicom), SCDMA (China Netcom large well-informed), DCS (1800MHz), PCS (1900MHz), PHS (PHS telecommunications) all mobile phone signals
