AUDIO JAMMER

INSTRUCTION MANUAL

ABOUT THE AJ-34

Size: 4.25@ x 2.5@ x 1.5@
Weight: 7 oz.

Battery: Use only a 9 volt alkaline battery.
The alkaline battery should be good for several hours of use, depending on the
volume setting.

THEORY

All types of bugging devices transmit or record every sound generated within its detection
range. The AJ-34 generates a sound that will mask the human voice. As long as the
volume of the conversation is lower than the volume of the AJ-34 no bugging device can
separate the conversation from the masking noise.

AJ-34 AUDIO JAMMER INSTRUCTIONS

The AJ-34 protects your conversations from eavesdropping by generating an
unfilterable masking sound which randomly varies in frequency and amplitude. All the
eavesdropper will hear is a loud hissing noise.

The AJ-34 is effective against any microphone based eavesdropping device including RF
transmitters (bugs), tape recorders, shotgun microphones and hard-wired microphones. It
will also protect against microwave and laser reflection types of eavesdropping which

monitors the sound waves reflecting off of glass surfaces such as windows.

USING THE AJ-34

The AJ-34 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 AJ-34.

Keep in mind that the larger the room is the higher the volume will need to be. The
AJ-34 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.

AUDIO JAMMER PLACEMENT

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 where 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.
