EO-J
DISCREET SIGNAL JAMMER
The EO-J discreet signal jammer interferes with cellular and
Wi-Fi networks in range, including 5G. It also protects against
eavesdropping and GPS tracking. With no external antennas,
it doesn't attract unwanted attention. The device provides
discreet protection of your office from confidential information
leakage. The range of the jammer is 5-20 meters.
Protects against position
tracking.
EO-J cancels cellular and wi-
fi networks including 2G, 3G,
4G and 5G signals.
Interferes with all commonly-used
local cellular network bands,
including 5G.
Blocks the two most commonly
used Wi-Fi frequencies
in the range, making it impossible
to transmit audio and video
via hidden Wi-Fi cameras.
Protects against eavesdropping
with wireless Bluetooth
headphones.
Protect Your Trade Secrets
Listening devices are now a widely available
and increasingly used part of the competition. Your
confidential meetings can be eavesdropped on by mobile
phones, installed GSM modules, or even Bluetooth
headsets. Not only are you at risk of information leakage,
but you may also lose the trust of your customers and
business partners. Protect your know-how with
the powerful EO-J signal jammer.
Prevents data transmission over
GSM, LTE, and 5G networks.
The jammer is completely
discreet due to its design
and does not attract any
unwanted attention.
Prevents eavesdropping by
wireless bluetooth
headphones.

TIP: For a high degree of protection, we recommend using the EO-
J jammer in combination with the EO-1 speech protector. For truly
comprehensive protection against unwanted audio recordings, see
the EO-1M speech protector and signal jammer. It provides all-in-
one protection of your privacy due to its combination of both
technologies.

Parameters
Safety information Important
Avoid contact with water and areas of high humidity at all times.
The device should not be exposed to dripping and/or splashing
water. When cleaning the device use dry materials only. Make
sure to protect the equipment from rain.
Do not use the device in areas with extreme temperatures.
We recommend using it in an environment with temperature
between 0° and 45°. Do not install the device near heat sources.
Avoid contact with parts that conduct electricity. Please, do not
remove the cover or casing of the device in any way to avoid
the risk of electric shock.
In case there is a ventilation opening on the device, make sure
it does not get blocked.
Use only accessories that were specified and supplied
by the manufacturer.
Make sure to not place the device on top of other electronic
devices or place electronic equipment on top of the supplied
device.
Do not place the device close to your ears. It emits high
frequency sounds that may damage your hearing. Prolonged
use of the device at high volume may cause hearing damage.
Use the device only when necessary and at the appropriate
volume.
Do not tamper with the power cord in any way. If the power
cord is mechanically damaged, stop using the device
immediately. Mechanically damaged cables, ruptured insulation
or frayed cables pose a risk of electric shock and also risk
of fire.
If necessary, have the equipment serviced by qualified
personnel and do not attempt to repair the device yourself.
Be wary of open flame – the equipment is made of flammable
materials. Never bring it close to an open fire.
Make sure that the supply voltage corresponds to the voltage
specified in the documentation.
For the best possible protection, we recommend using the acoustic
noise function which allows you to record your own voice in your own
language and overlap your conversation with it. The recorded voice is
then randomly generated to create a sound barrier against
eavesdropping via a stethoscope and laser microphones. Additionally,
it protects against the most cutting-edge forensic cleaning
technologies.
Although the device does not guarantee a 100% jamming
effectiveness, it greatly outperforms competing solutions.
Due to its configuration, it can guarantee high effectiveness when
used against microphones on devices such as dictaphones, wiretaps
and seismic microphones, computer microphones, headsets, cameras
and mobile phones.

The electrical plug must remain easily accessible in case
of an emergency shutdown. Do not overload the sockets
with the plugged device.
If the devices include a battery, do not expose the battery
to excessive heat, fire, etc., as there is a risk of explosion. Also, do not
subject the battery to high altitudes or low air pressure. Always use
batteries recommended by the manufacturer. Wrong batteries may
interfere with the proper functioning of the product.
When using the ultrasonic noise generator to overwhelm
all microphones in the vicinity, certain limitations may arise due
to the laws of physics. Some of the microphone designs may be more
susceptible to be jammed than others. Therefore, the effectiveness
may be different for each of the designs. The maximum effective
range of the generator can therefore also vary by up to several times
depending on the type of the microphone. Additionally, the generated
ultrasonic noise can bounce off different surfaces and is unable
to penetrate most materials to any greater depth. It is recommended
to use a sufficient number of devices and then position them
appropriately in the room to ensure the best possible protection
of privacy during meetings.
