MNG 300 Skeller
Noise generator
The MNG-300 Skeller creates an additional barrier interference which masks your speech. It is when a certain noise level is reached that listening devices will record or transmit information, it is extremely difficult, or impossible, to extract the speech component from this noise. Since the generator creates a "white" noise, which is distributed throughout the speech range of the spectrum of human voice, cleaning of the noise is not possible, if the level of noise is sufficient.
The housing of the unit is made from a very reliable material and is extremely durable, guaranteeing a long life for the device. The size of the MNG-300 Skeller is comparable to a pack of cigarettes and can even be carried inside one in order not to attract attention, although an attractive leather case is supplied.
Features
The MNG-300 Skeller will allow you to improve the security of your negotiations and protect you against listening and recording devices. When used in the correct manner the MNG-300 Skeller will protect you from:
- voice recorders (tape and digital)
- microphones
- wireless microphones
- stethoscopes, laser window stethoscopes
- GSM-transmitters, etc.
Usage
MNG-300 Skeller is a tool, which complements and reinforces the measures taken to protect you from eavesdropping and recording. First of all the security of your conversation depends on yourself, and then from the device. Therefore, during sensitive negotiations it is important not to increase the volume of your voice. Imagine that you are sitting in a crowded coffee shop and do not want to be heard by the people at the next table; that means your speech should not be too loud. If possible, lean forward towards your interlocutor or sit closer to each other, then place the generator on the table between you. Please note: it is not possible to use only one MNG-300 Skeller if the number of participants is more than 4. In this situation, it may be necessary to use additional devices from the Skeller + series.
Also, while in use do not hide your generator, e.g. in your pocket or a bag! Your conversation should be "drowned" in noise; therefore the unit should be as close to the speakers as possible. Do not decrease the volume of the MNG-300 Skeller; always use it at maximum volume and speak quietly.
If your companion has a recorder about his person, he will record himself, but not you, as long as your voice is not 'over' loud.
Modern digital recorders use a compression of sound during the recording process. Such a procedure "shrinks" unnecessary pauses and removes irrelevant sounds. Thanks to this noise cleaning procedure during the process of recording digital voice recorders are more resistant to noise generators. Therefore, the recorder must "hear" more noise than speech, and therefore you must comply with the low volume of conversation and keep the generator closer to the potential location of a "bug".
Analog transmitters (radio microphones) use a classical scheme of sound processing, which clogs the noise much easier than that of digital voice recorders. I.e. wireless microphones are suppressed easier than recorders.
The MNG-300 Skeller is powered by a 9V battery and can work from 5 to 10 hours. Replace the battery by turning the screw on the underside of the housing. Turn the screw and shake the unit slightly to open the battery compartment.
If the recorder can be in an undisclosed location, somewhere around you, you may need to use an additional generator. Place 2 generators between the interlocutors, placing them in different directions, or one between the interlocutors, and the second - somewhere behind you or to one side.
