*effectively shielding CDMA / GSM / DCS / PHS / 3G / 4G / 5G and Wi-Fi signals.

*with network jamming module, remote control all the jammers via computer in one blocking system.

1) network control, which can remotely monitor equipment voltage, current, power, equipment temperature and change working status;

2) time switch machine, energy saving and environmental protection, extending equipment life cycle;

3) the device displays voltage, current, power and equipment temperature in real time (optional);

4) the internal motherboard integrates overvoltage and undervoltage protection functions. When the voltage reaches the upper and lower limits, the motherboard is powered off and alarmed.

5) the internal motherboard integrates the temperature detection function. When the temperature reaches the upper limit, the motherboard is powered off and alarmed.

6) the working time can be freely set by the user according to the actual use requirements in the blocking software.

*built-in high gain directional antenna, easy hidden use, not easy to find out, and avoid affect surrounding signals.

*low noise, good cooling system with 4 cooling fans inside the jammer, can support 24 hours continuously working.

*with triangle bracket holes, easy to place anywhere as you need.

4. Operation Instructions

*open the package, take out the jammer and its accessories.

*hang the jammer onto the wall with hanging height for 1.5-2 meters, choose a best place where its 4 fans with good cooling condition, do not shield and affect the fan space.

*the installation location in the space of different sizes can be decided according to the following fig.

Ex1: indoor small space (less than 200 square meter)

Ex2: indoor big space (more than 200 square meter, preferably by the cellular mode)

Ex3: outdoor big space (more than 1000 square meter, preferably by the cellular mode)

*when the jamming range coming to dwindle, it means the angel the device installed is not the best position, please change and try other different angels, please keep in mind, do not point the device to base station.

*since the valid scope covered by the jammer is a round area with the isolator as the center.

*please keep away strong electromagnetic sources with heat sources to ensure high isolation affect and stable operation for a long time.

*switch off the device in time when not using it, lest the normal operation of mobile phones be affected.

*while using the isolator outdoors, be sure to keep it away from water or damp.

*keep away from caustic gases and liquids, and be sure to make it dust-proof and moisture-proof, lest the aging of the components inside should be accelerated.

█Smart Jammer System software usage precautions

(1) The order in which the software is used for the first time is:

1) “Registration”: The user sends the PID information to RICE GROUP’s customer service, and the customer service will use the unique registration code generated by the unique PID to feed back to the user. The user only needs to input the registration code correctly to start using the intelligent management system software.

2) "Position Manage": Set the installation location for subsequent installation selection of the device;

3) "Working Hours": set the time period for the subsequent working hours of the equipment to be selected;

4) "Device Manage": Set the unique number of the device, unique IP address, installation location, working hours.

(2) The IP address of the same device must be the same as the IP address of the TCP/IP module.

(3) The timing system is a 24-hour system. If there is a cross-day situation when setting the switch working period, you should set a more time period. For example, in order to prevent students from playing mobile phones to affect sleep, set the smart screen of the dormitory to 23 o'clock to turn off the phone at 3 am, in this case should be set to: time period 23:00:00 - 23:59:59 , time slot 20:00:01 - 03:00:00

6. Application Area

Suitable to be used in prison, jail, government, meeting room, conference room, museum, gallery, theater, concert hall, church, temple, restaurant, classroom, training center, factory, bank, train, car bus etc, at the places where mobile phone is prohibited to use, to provide you a safe environment.
