Signal Knight Brand Ultra-thin Cellphone Jammer

Model: SK-6 Ultra-thin Cellphone Jammer

Introduction:

SK-6 cellphone jammer is more and more popular used in examination halls, examination rooms, test rooms, libraries and so on. The cellphone jammer is the best instrument can help examiners to prevent students cheating with cellular phones in the examinations. SK-6 cellphone jammer is the latest electronic product which transmits low power radio signals to block the communication signal bandwidths in GSM, CDMA, PHS, DCS, IDEN, UMTS, GPS, WiFi, Bluetooth, etc. Beijing Signal Knight is a professional cellphone jammer manufacturer based in China Beijing; we can design and develop any types of cellphone jammers for different clients’ demands. Nowadays, the cellphone jammer has become the necessity for schools, universities, testing centers, and so on.

Features of SK-6 Cellphone Jammer

• Show the working power on the shell with green lights
• Prevent cheating by using cellphone in the examinations
• Keeping you away from the noise or disturbance of unexpected cellphone calls or SMS in the class time or meeting time.
• Mini-size medium power cellphone jammer
• Low weight and Nice texture and color
• To block wireless phone communication links within an effective area.
• No transmissions or receptions of cellphone call in coverage area.
• All specified frequency bands will be blocked simultaneously.

Specification: 

 *The mentioned jamming distances are based on the base station signal strength; actual jamming distance will be varied depending on the strength and type of cellular system.  

How to Install:

1.     Install this device at the height about 1.5-1.7m will get the best jamming result, keep all the antennas in vertical.

2.     Never install this device close to the wall; the wall will affect the interference signals. Put this device 30-50cm away from the wall.

3.     One set of this device can block all types of cellular system including analog (AMPS, TACS, NMT) and digital (GSM, DCS, PDC, TDMA, PHS, PCS, iDEN, CDMA, WCDMA) signals up to 30m radius, covers an individual room of around 2800 square meters.

4.     To cover an area bigger than 2800 square meters, please install multiples of this device to ensure better jamming effect, e.g. in an individual space of 3500 square meters, you should need to install 2 or more devices working together.

5.     This device is not able to cover different spaces divided with walls. Install individual jammers in different partition of a building to ensure the best jamming effect.

How to operate the SK-6 Cellphone Jammer:

1.     Install the antennas fully correctly in vertical firstly.

2.     Plug the power adaptor into the electricity outlet (110V-240V)

3.     Before turn on the power switch, always check if the antennas are installed securely. If you turn on the power switch without the antennas installed on this device, it shall heavily damage this device. Never remove the antennas when the device is working; otherwise you will void the warranty.

 Notice of Use SK-6 Cellphone Jammer:

Be sure to connect all the antennas firstly before the power supply is switch on. Please do not take off antennas when the machine is working. Otherwise, it should cause heavy damage to the device and cause the device out of work. It will also void warranty.

Antennas shall be used vertical to the ground, working more efficiently.

Please don’t put the jammer in the water and fire to avoid using in the bad. Condition of over-wet, over-hot, high-voltage and high magnetism.

Use several units in the same place will get bigger coverage area.

For better performance indoors, use this device in an individual space. The device is not able to cover different spaces divided with walls. Install individual jammer in different partition of a building to ensure the best jamming result.

The jamming area is influenced by the location of the cell tower and the obstacles between cell tower & the cell phone jammer. It means that in normal condition if the distance is close between the cell tower & the cell phone jammer, it will have very less jamming area. Likewise, if there are obstacles & walls between the cell tower & the cell phone, the cell phone jammer will give less jamming area.

Usually, at the same place, you will get longer jamming distance indoor, because the wall and floor will reduce the base station signal strength.

Any ruin and disrepair caused by incorrect operation and disassembly will exclude from the repair with free of charge.

1.     Unauthorized repair or dismantle of this device will void all the warranties.

2.     Antennas shall be used vertical to the ground, working more efficiently.

3.     Please do not take off antennas when the machine is working. Otherwise, it should cause heavy damage to the device and cause the device out of work. It will also void warranty.

4.     Install the antennas before switch on the device, otherwise will heavy damage the jammer.

5.     Persons with Pacemaker implants are prohibited from using this device.

6.     Avoid water; over-wet, over-hot, high-voltage and high magnetism.

7.     Do not store this device in an excessively hot place.

8.     Avoid knocks or dropping this device.
