Use Scene of Nonlinear Junction Detector

Government Secrecy Department
State government organs such as public security, justice, prisons, education, troops, largescale central enterprises and secret-keeping units have very strict requirements on information security and leak prevention. Prior to the major meetings, the secret-keeping departments must conduct security tests on high-level conference rooms,head leader’s meeting offices, foreign guests; reception rooms and secret-keeping places, so as to prevent the hiding of illegal equipment such as eavesdropping and secret shooting from being inappropriate places. Findings eventually lead to the leakage of conference information, major confidential information and technology, and irreparable economic losses to the state and units.
Security Inspection of Large-scale Activities
In order to ensure the personal safety and information security of politicians, business leaders and participants, the organizing committee needs to appoint a professional security inspection team to conduct security inspection in all places ahead of time and strictly block them. Nonlinear Junction Detectors are used to detect eavesdroppers and secret photograph equipment, recording equipment, remote control explosive devices and other illegal equipment to ensure the safety of the activity site.
Confidentiality Inspection of Commercial Organizations
Large commercial organizations such as listed companies, multinational corporations, trade associations and so on, in order to ensure that business secrets are not leaked, need to carry out strict information security checks on internal high-level conference rooms, chairman’s offices and business negotiation venues, to prevent mobile phones, eavesdroppers and other SIM card
Cheating Prevention In Education Industry Examination
In places such as college entrance examination, high school entrance examination, civil servant examination and college marking, non-linear junction detectors can be used at the entrance of the examination room to prevent cheating devices from being brought into the examination room by hiding in the examinee’s ears, glasses or other parts of the body, so as to ensure the fairness and fairness of the open selection.
Privacy Protection Inspection of Personal Residence or Hotel Room
In order to ensure the safety of personal privacy, non-linear junction detectors can be used to detect the security of the surrounding environment in private spaces such as personal residence, Hotel room, shopping mall changing room, toilet, and entertainment places, to ensure that there are no hidden pinhole cameras, eavesdroppers, recording pens and other electronic devices to ensure the safety of personal privacy

Operation guide

Power button:
- switch on by long press 3 seconds, switch off by long press 3seconds, there is indicator light built-in button;
Txbutton:
- transmitting power adjustment button,including high,medium and low three levels,built-inindicator lights;
Rxbutton:
- receiving sensitivity adjustment keys, including high,medium and low three levels ,built inindicator lights;
Sound button:

Screen

The screen interface mainly displays the battery power, alarm mode, and transmitting power level and received second and third harmonic signal strength. The detecting process and result are as below: iSecus DT-820Plus
Portable Non-linear Junction Detector 4

Battery status display
Audible alarm mode indicator
Indicates that an electronic product has been detected
Vibration alarm mode
Headphone mode indicator
Indicates that the device is in the process of detection
Transmitting power intensity indicator
Indicates the received second harmonic signal strength
Indicates the received third-order harmonic signal strength

When a suspicious electronic device is detected in the target area, the second harmonic signal strength is significantly stronger than the third harmonic signal strength, and the electronic product icon is displayed on the screen.

Charging instructions

The device supports charging using the Type C interface.The indicator light of power button will always be orange when charging, and battery icon will be shown as charging status on screen if device is on.

FAQ

Q: Can’t boot when I press the power key, how to deal with it?
- A: Normal booting requires long press of the power key for more than 3s; if you press and hold the power key for 3s, it still cannot be turned on. It may be caused by the battery being exhausted. You need to connect the power adapter to charge.
Q: How to detect target electronic products that are far away?
- A: Increase the TX Power; or increase the RX Gain
Q: Electronic products have been detected but there is no sound alarm, how to deal with?
- A: It is possible to set the machine to silent mode, and you need to exit the silent mode to generate an audible alarm;
- Turn up the sound;
- Check the horn for blockage.
Q: When the machine will auto shut down?
- A:After the machine head is folded, it will auto shutdown after 5 seconds;
- If the machine detects that it has not moved for 5 minutes, it will auto shutdown;
- When the battery power is lower than 10%, the machine will auto shut down.
Q: After the box is transported or stored for a long time, there may be a phenomenon that it cannot be opened or deformed. How to deal with it?
- A: This situation is caused by the change of the air pressure difference inside and outside the box. The pressure reducing valve can be rotated to make the internal and external air pressures uniform, then the box can be opened, and then the pressure reducing valve can be tightened to avoid water leakage.
