This Manual is intended

for explanation

“NR-CHP” Non-linear Junction Detector

design & principle of operation

as well as directions for its use.

For proper equipment use,

study this Manual in depth.

NR-CHP Operation Manual

The Device has an open UHF radiator

of electromagnetic energy.

In active mode it represents

a source of active interference

that could cause certain malfunction

of radio-electronic equipment

located in close proximity

It is the responsibility of the User

to comply with the corresponding

Radio Communication Regulations

of the country where ‘NR-CHP’ NLJD

is being used

1. APPLICATION

NR-CHP Non-linear Junction Detector (fig. 1) is intended for

searching concealed electronic devices that contain semi-conductor components.

This Detector can be successfully utilized for suspect person inspection at a certain check point.

NR-CHP can detect typical target in every operational mode: active,

stand-by or even switched-off.

2. FUNCTION NR-CHP represents a portable tool that consists of antenna system,

transmitter and two receivers adjusted for double and triple frequency of transmitter’s probing signal. Both transmitter and receivers are placed in a Main unit body.

Main unit is fabricated as mono-block in a compact plastic body with an easy-to-use handle and control panel on the back side of the body.

The UHF probing signal is converted into a poly-harmonic one on the radiated nonlinear elements (semi-conductive items or corroded metal-oxide-metal junction) and retransmitted, better say – ‘scattered’ into ambient space.

Retransmitted 2nd & 3rd harmonics of the probing signal are received and processed simultaneously by receivers.

The received signals levels are reproduced in an audio form and its volume is proportional to the received signal level while its tone corresponds to an appropriate harmonic.

If necessary the received signals level can be reduced by ATT buttons (see Main unit control panel below) and monitored by corresponding LED indication.

NR-CHP OPERATION

OPERATION CONDITION AND RESTRICTIONS

After long-term exposure to a low temperature keep the device packed in a standard packing at least 2 hours for evening up its temperature with the environment.

NOTE: Operating NR-CHP keep corresponding safety measures.

Safety precautions for the open RF emitters:

- Avoid prolonged presence of personnel in a Main lobe of NR-

CHP antenna’ diagram.

NOTE: Probing signal power density at the distance of 1 meter along the maximum of NR-CHP antenna directional radiation pattern does not exceed Russian State Standard 12.1.006-84 (Russian State Sanitary Norm) for UHF-equipment serviceman under continuous 8-hours operation.

GETTING STARTED

Take NR-CHP components out of standard packing.

Open battery compartrment at the back side

of the Main unit.

Insert two fresh rechargeable cells (fig.10)

into the cell holder keeping cells polarity

specified on the holder side wall (see an

arrow). Install it into the battery

compartment.

Close the battery compartment cover and lock it.

1. Push (‘On”) button to switch on Detector (fig.11).

The following mode is set on default confirmed by corresponding LEDs:

– transmitter is on, – receivers are on, – input signals

attenuation is at -10 dB

2. Use ATT button to adjust maximal receiver sensitivity (fig.12).

3. Aim antenna at various directions and evaluate noise background in that particular point.

Choose the direction without any noise reaction for Detector workability test.

NR-CHP WORKABILITY TEST

Place test-unit (imitator) at a chosen direction 0.5…0.7 m from antenna cap.

At that a tonal signal should be heard. Detector is ready for operation

SEARCHING OPERATION

NR-CHP Detector represents a high sensitive radio-electronic device. Getting started remove from the your pockets and outfit any items that contains semi-conductive components.

Carry out searching operation with maximal receiver sensitivity. Use ATT button to activate this mode (see fig. 10 for reference).

The receivers sensitivity is determined by real noise environment situation right on spot, for instance, by extraneous emission activity and/or non-lineal junctions that cannot be removed from the area under control.

USEFUL HINT: If necessary, depending on the noise/ interference situation adjust an adequate received signal attenuation by means of ATT-button.

For instance, -20dB (see fig.14)

By the end of operation – switch off Detector. Remove battery from the body and pack complete set in a Carry bag

(fig.9).

EMERGENCY ACTIONS

- In case of the equipment malfunction that cannot be

corrected by the operator, Detector operation should be stopped.

- If Detector was exposed to an external mechanic,

electromagnetic or climatic impact and temporarily lost its workability, then before restoring the operation it is required to carry out its visual checks and a corresponding functional test referring this Manual.

OPERATION OF THE FAULT DETECTOR

IS NOT ALLOWED.

10. BATTERY CHARGING (fig. 15).

Insert 2 or 4 cells (pos.3) into Soshine Charger chamber (if necessary slide ‘minus’ spring contact) Pay special attention to cells polarity referring indication on the charger chamber Couple AC power adapter or DC 12V car adapter to the socket on a side wall of the Charger (pos. 2). Connect AC power adapter to the Mains (100-240V, 50/60 Hz) or Сar adapter to a corresponding cigarette lighter socket. After switching on the power the Charger will check every charging channel operability and initiate the charging mode.

Charger operation precautionary measures

- Do not try to charge primary cells! That can initiate an explosion and provoke the fire. Acceptable elements should have an inscription “Rechargeable”.

- Do not block vent holes on the bottom of the charger housing.

For instance, don’t place it on a soft, fleecy surface (carpet, blanket, seat covering and etc.).

- Charger is intended for indoor use only. Protect the device from

moisture and perspiration water. Do not switch on the charger and/or power adapters with the obvious presence of moisture inside the device.

- Do not try to disassemble or modify the device. Do not use it as a

surrogate power source for a certain gadget. The device terminals are intended for charging appropriate cells only.

- Charger is an electronic device with high frequency circuits and

violent operating current. The wrong operation could cause an electrical shock.

- Do not leave the charger and/or AC power adapter coupled to the

Mains unattended for a long time. In spite of several protection circuits used in the charger circuit there is certain probability of abnormal mode that will cause the fire.
