1.4.2. The device runs under command of micro controller with embedded software.
1.4.3. Device’s transducers emit special high frequency sound waves (pattern of the sound is determined by
software in accordance with the specially developed algorithm) with the sound pressure reaching 120 dB at 1 m
distance from the transducers. Additionally, the speaker produces an acoustic speech-like signal with adjusted
volume.
1.4.4. The device is powered by the installed batteries or by the supplied external power source (battery
charger).
1.4.5. The installed batteries are charged by the supplied external power source (battery charger).
2. INTENDED USE.
2.1. Operating restrictions
2.1.1. Ultrasonic pressure level of the operating device at a distance of 1 meter or less may exceed the
maximum safety level of emission for people according to Sanitary Regulations and Norms 2.2.4/2.1.8.582-96
that may cause damage to your health!
2.1.2. Do not hold the running device in close proximity to person’s ears - this may cause headaches and
temporary hearing loss.
2.1.3. Do not damage the ultrasonic transducers that are located behind the grid by foreign objects. Damage
of the transducer may cause improper operation of the device or render it unusable!
2.1.4. Do not cover or block the ultrasonic transducers or holes in housing cover by your hand or piece of
clothes while the device is in operation!
2.1.5. Use only the supplied external power source (battery charger) for charging the installed batteries.
2.1.6. Children should not use the device!
2.1.7. Most of the pets (dogs, cats, rodents, etc.) rather painfully react to ultrasonic waves, so please avoid
the use of the device in their presence when applicable!
2.1.8. Store the device with fully charged batteries. Monitor the batteries charge level, do not let them be
fully discharged! In this way the batteries life will be extended.
2.2. Device usage.
2.2.1. ON/OFF. In order to switch ON the device, turn the volume controller (item 6) clockwise (in volume
increasing direction) until you hear a click. Then power indicator will start to flash (item 5). Speech-like signal
appears and accelerates upon further turning of the volume controller. In order to switch OFF the device, turn
the volume controller (item 6) counterclockwise (in volume decreasing direction) until you hear a click
2.2.2. TURBO Mode *. In this mode, the effectiveness of tape recorders jamming is achieved by application
of the additional ultrasonic transducer that produces frequency signals. In order to switch ON/OFF the mode
press the button (item 3). Yellow flashing indicator (item 3) shows that the device is operating in TURBO
Mode.
*
NOTE in this mode, ultrasonic signal modulates the audio signal that becomes slightly audible to human hearing,
even at zero volume of acoustic speech-like signal. This somewhat complicates the possibility of completely hidden use of
the device.
2.2.3 Installed batteries charge indication.
