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 3
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)
Fig. 14

NR-CHP Operation Manual 15
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.

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.
