output power of low frequency 100-800MHZ can be as high as 10W,
high-frequency 800-2700MHZ single output power of 5-8W.
Innovative technology of manufacturers, full-band wireless signal
shielding equipment, wireless headset, Bluetooth, interphone signal
The full-band wireless signal shielding apparatus is a high-tech,
new-type information security and security product that has been
successfully developed by our company in response to the detailed
requirements of various wireless signal plagiarism tools in the
current examination room in response to the requirements of the
National Education Ministry's standardized examination room
construction. The device effectively blocks all cell phone signals
(CDMA, GSM, DCS, PHS, TDSCDMA, CDMA2000, WCDMA), walkie-talkies,
wireless, bone conduction headsets, 2.4G (WLAN, WIFI, Bluetooth),
cameras, and built-in LED display digits in the examination room
Transmission and reception tools (rubber files, watches, rulers,
pens, glasses probes) and other wireless copy tool signals.
Selected in the list of relevant equipment for the standardized
examination room of the Ministry of Education Examination Center.
Installation and usage instructions
1 installation steps and methods
1.1 Remove the shielded instrument host from the box.
1.2 Hang the shielding instrument on the wall or place it in the
appropriate position. The optimal installation height is 1-1.8
1.3 Insert the AC input of the power supply into the mains socket,
and then turn on the power switch. The work indicator light on the
power supply is on.
1.4 For large and small space installation location point method,
as shown below
Example 1: Indoor Space (less than 200 square meters)
Example 2: Indoor space (greater than 200 square meters, multiple
units must be used)
Example 3: Outdoor large space (greater than 1000 square meters,
with multiple cellular effects best)
2.1 The machine is a built-in antenna and the antenna does not need
to be installed. Power on the host and turn on the switch.
2.2 The effective coverage area of the shielded instrument is a
circular area centered on the shielded instrument. Therefore, when
using it, make sure that the shielded instrument is properly
positioned so as not to produce a blind corner.
2.3 The Inner Directional Antennas 10 Bands Cell Phone Signal Jammer should be placed in a well ventilated place, try to avoid the
obstruction of large objects, avoid strong heat source and strong
electromagnetic source. To ensure the shielding effect and
long-term stable work.
2.4 When shielding the instrument, do not stack other items on it
and disassemble the antenna so as not to affect the shielding
effect and damage the machine.
2.5 When the instrument is not used, the power should be cut off in
time to avoid affecting the normal operation of the mobile phone.
2.6 When using shielded equipment outdoors, pay attention to
2.7 When the area of the used site is larger than the effective
shielding range, it is recommended to use multiple shielding
devices for honeycomb installation to ensure the shielding effect.
2.8 Keep away from corrosive gases and liquids, and do dust and
moisture protection so as not to accelerate the aging of the
internal components of the equipment.
2.9 When placing outdoors or in the wild, care should be taken to
install additional protective devices in the presence of
destructive animals such as rats and ants.
2.10. The equipment must remain upright.
2.11 The power cord must be fully open so that the power supply is
as far away from the equipment as possible.
2.12 Keep dry, do not invade any liquid, do not get near fire.
2.13 Please attach the product model mark to the area to be
Do not disassemble without authorization from the manufacturer.
3.1 This shielded instrument is a maintenance-free device and does
not require maintenance
3.2 When wiping the surface, do not use chemical solvents and avoid
water in the machine.
3.3 Screening When not in use, the instrument should be stored in a
dry and ventilated place to avoid prolonged exposure to salt spray
and harmful gases.
