Page 5: Application
Operation Manual 1. APPLICATION Non-linear Junction Detector NR- (hereinafter referred to as Detector) is intended for concealed electronic devices detection which contains semi-conducting elements (that can be both enabled or disabled). Detector can detect typical targets in every operational mode: active, stand-by or even switched-off. Detector ensures efficient searching and precise target items localization in building envelope elements (floor, ceiling and walls), interior elements and pieces of furniture, clothes and... -

Page 8: Function
Operation Manual 4. FUNCTION NR- Detector represents a portable tool that consists of antenna system, transmitter and two receivers adjusted for double and triple frequency of the transmitter’s signal. In a ‘search’ mode the probing signal is converted into a poly- harmonic one on the radiated nonlinear elements (semi-conductive items or corroded metal-oxide-metal junctions) and retransmitted, better say –... -

Operation Manual 8. OPERATION CONDITION AND RESTRICTIONS After long-term exposure to a low temperature keep Detector packed in a standard packing at least 2 hours for evening up its temperature with the environment. Operating NR-T keep corresponding safety measures. Safety precautions for an open RF emitter: - Do not direct NR-T antenna to the human eyes from the distance less than one meter. -
Page 16: Getting Started
Operation Manual 9. GETTING STARTED. Unpack NR-T Detector set. Connect remote loudspeaker to the corresponding jack on the Main unit body (see fig.2 for reference). Install two fully charged Li-Ion Soshine 18650 cells into Detector’s battery compartment. Pay attention to their polarity referring the label on the Main unit front wall. -
Page 17: Nr-T Workability Test
Operation Manual Use ATT button to adjust maximum receiver sensitivity. Turn antenna unit at various directions to estimate noise condition at the device receiving frequencies. Choose the direction with minimum interference level. Carry out Detector workability test: 10. NR-T WORKABILITY TEST Press PWR button to set minimum probing signal power confirmed by corresponding LED (item 2 at the fig.4). -
Page 18: Practical Operation
Operation Manual 11. PRACTICAL OPERATION Switch-on Detector and carry out its functional test referring item at the page 17. WARNING: NR-T detector is a high-sensitive radio electronic device. Before operation, please, make sure to remove all semiconductor-containing items from your clothing and munitions. NOTE: The practical probing signal level and receivers sensitivity are defined by the interference environment right on spot of the operation. -
Page 19: Emergency Action
Operation Manual The detected target origin can be identified by comparing the levels of input signals of the 2 and 3 harmonics - use "SND" pushbutton to switch over between these modes. USEFUL HINTS: If the 2 harmonic input signal is much higher than the 3 harmonic reply, this can testify to a good chance of detecting semi-conducting elements within the search range of the Detector. -
