  • Keep your private conversations private! TKS-213.B protects your sensitive room conversations by generating a random masking sound which desensitizes any near-by microphone. Effective against any microphone based eavesdropping device including tape recorders, transmitters, hard-wired microphones (including contact type) and shotgun microphones. It also protects against microwave or laser reflection pickups. Because the sound from the jammer varies randomly in frequency and amplitude, it cannot be easily filtered and the only sound the eavesdropper will hear is the jammer noise.
  • The convenient end-mounted control lets you select the level of protection for your situation. One unit will protect up to 150 sq. ft. For protecting rooms larger than this, we recommend and additional jammer for each 150 sq. ft. of area. The illustrated instructions show suggested jammer placement for different types of rooms and situations so that you can use the jammer effectively.
  • This product should be placed in the center of the conversation area with the speaker facing up. Turn the unit on and adjust the volume control to an appropriate level. Remember that for maximum protection you must talk lower than the sound generated by the TKS-213.B.
  • Keep in mind that the larger the room is the higher the volume will need to be. The TKS-213.B should provide a masking noise over an area of 150 square feet at full volume. For very large rooms, we recommend an additional audio jammer for each 150 square feet of area.
  • Because bugs can be hidden just about anywhere, try to conduct your conversations without any devices such as telephones, lamps, radios, etc. between you and the person you are talking with.
  • When choosing where to place the audio jammer, pay close attention to the layout of the room. In a small room with no windows placement in the center of the room would work best.
  • For an office with a window, placement should be were both the window and the desk are covered.
  • In large rooms or rooms with multiple windows more than one jammer will be needed to cover both the windows and the rest of the room.
