2.1.4. Do not cover or block the front panel while the Device is operating.
2.1.5. Children must not use the Device!
2.1.6. Most of the pets (dogs, cats, rodents, etc.) rather painfully react to ultrasonic waves, so please
avoid using the Device in their presence when possible.
2.2. Device usage
2.2.1. ON/OFF:
-
Connect the external power source to the Device. Then power indicator will start to flash (item 3 in
Figure 2);
-
Press
button on the remote control. Then green operation on/off indictor will start to flash (item 4
in Figure 2). The Device starts generating inaudible ultrasonic interference;
-
Set the necessary speech-like interference volume level by turning the rotary knob (item 5 in Figure 2);
-
Press
button on the remote control in order to switch the Device off.
2.2.2. Point the Device’s transducers in the direction of assumed eavesdropping devices (microphones,
dictaphones, spy bugs etc.). Optimal range is up to 2 meters (7 feet) from the transducers. Speech-like
interference volume should be adjusted so as to hear your interlocutor well. Talking in a low voice is
preferrable.
2.2.3. Do not switch speech-like interference on for inconspicuous use of the Device. However, the
Device’s protection level decreases if used without speech-like interference.
The manufacturer cannot
guarantee that if you use only ultrasonic signal (or insufficient level of acoustic speech-like signal volume) all
voice recorders and recording devices will be jammed.
3. MAINTENANCE
Maintenance requires cleaning the surface of the Device.
