The NLJD “LORNET-24” automatically finds the best receiving frequency channel free of noise and distortion providing flawless operation even in the complicated electromagnetic environment. - Page 4 The frequency tuning algorithm implemented in “LORNET-24” automatically selects the RF probing signal frequency such that the noise level in 2d harmonic receiving channel is held minimal, while digital processing of a demodulated signal gives maximum sensitivity. There are two types of radiated signals: •...

Page 8: Appearance
4. Appearance The appearance of the device is shown in Fig. 1, where: 1- LED indicator; 2- ransceiver antenna unit; 3- control panel with a power section and battery (fixed derneath). Fig. 1 Wireless earphones, chargers and additional batteries are not shown. - Page 9 5. Purpose of the Detector Basic Units 5.1. The transceiver antenna unit with built-in LED indicators (shown in Fig. 2) is used for: Fig. 2 • Analysis of distortion and interference in the instrument receiving path, which is made each time the detector transmitter is switched on.
- Page 10 • Reception and digital processing of the 2nd and the 3rd frequency harmonics. Simul- taneous display of the 2nd and the 3rd harmonics levels gives the opportunity to dis-tinguish with a high reliability between signals of artificial semiconductors integrated in electronic devices and natural corrosive ones which may appear at oxidized junc-tion points of various metals.
- Page 11 Fig. 3 Fig. 3: 1- Fixing device; 2- Hinge joint. 5.3. The control panel is used to control operation of the detector. It consists of the case combined with a battery and fixed on the arm. The control board, buttons for operation modes control and display LEDs are placed in the package.

- Page 13 The following buttons refer to the «AUDIO» group: 1- LEDs and LSTN button for switching of acoustic indication to the output of the 2nd or 3rd harmonics. 2- LEDs and OUT button for switching acoustic output to earphones or a built-in loud-speaker. 3- LEDs and RF button for switching between types of the radiated signal (CW –...
- Page 14 Fig. 5 9,10- Volume buttons for volume control (↑ – high, ↓ – low). Functions of control panel indicators: continuous light of any indicator corresponds to “on” position, absence of light – to “off” position. Simultaneous flickering of all indicators on the panel shows that the battery is discharged and needs to be replaced.
- Page 15 5.5. Battery charging is to be made with a power adapter and a battery charger sup-plied with the instrument only. Using other chargers is not allowed. For charging it is necessary to connect a low-voltage connector of the power adapter to the socket placed underneath the front side of the control panel.
- Page 16 In case of a failure (charging is not complete within five hours) a charger switches off automatically, both LEDs will go out. 5.6. Wireless telephones consist of a receiving device and earphones. Appearance of the receiving device and position of control units are shown in Fig.7 Device operation order: •...

30 minutes. 7.2. To start operation set the battery and turn «LORNET-24» on by the power switch placed on the control panel (Fig.5). The 2nd and 3rd indicators on the control panel will light up, indicating that the... - Page 19 detector has been powered on. One yellow LED should be lighting on the antenna unit (a circle scale of the probing signal power indicator). Its initial position corresponds to the maximum power of the probing signal. The probing signal transmitter is off (it is turned on after pressing PWR button only).
- Page 20 To switch over to the manual mode of the probing signal power control (MNL indicator lights up) press one of LEVEL buttons after the probing signal transmitter has been turned on. Turn the probing signal transmitter off and then turn it on for a reverse switch over. If it is necessary to tap the third harmonic response turn on mode 3–RD using LSTN button on the control panel.
- Page 21 Attention: 1) Do not direct the antenna towards the operator and people nearby. 2) While operating the device constantly monitor batteries state replacing them in-time (by the indicators signal). The batteries must be kept fully charged. 3) Charging should be done with a charger supplied with the instrument only.

8. Search Recommendation 8.1. If possible remove electronic devices from the room examined. If it is impossible, examination should be done at a decreased radiated power. 8.2. Set maximum radiated power level and one of the operation modes of the receiver. 8.3. - Page 23 8.7. Remove the antenna unit from the surface examined or decrease output power and repeat measurements stated in 7.4. of the present manual. For a more accurate location as well as for protection of receiving devices from overload it is possible to de-crease the signal level using attenuators.
