OPERATION

Real Time Clock Battery

An internal CR2032 coin cell battery provides power for the real time clock function and for maintaining
saved user settings. The Real Time Clock (RTC) battery should provide years of service. In the event that
the clock on the ORION 2.4 stops functioning or user settings are no longer saved, the Real Time Clock
battery will need to be replaced.

To replace the Real Time Clock battery:

1) Open the battery door and remove the product’s Lithium Ion

Battery.

2) Remove the Phillips head screw in the panel above the battery

compartment.

3) Slide the battery tray that rests above the battery

compartment out of the unit. Do not disconnect the cable

attached to the circuit board.

4) Locate the CR2032 battery on the right side of the battery tray

circuit board.

5) Remove the old CR2032 battery from the battery

clip and replace with a new CR2032 battery.

Observe the battery polarity marking on the holder

clip when replacing the battery; the positive (+) side

should be facing up, away from the circuit board.

6) Replace the battery tray and secure with the Phillips

head screw. Be careful not to pinch the attached

OPERATION

After taking the ORION 2.4 out of the case, follow these simple steps to
begin using it:

1. Place one of the provided rechargeable batteries in the battery compartment

2. Rotate the head for easy viewing

3. If preferred, extend the telescoping pole to a convenient length

Procedure

When the ORION 2.4 is turned on, it scans and displays the Transmit, 2nd Harmonic, and 3rd Harmonic
spectrums. If the Frequency Mode is set to automatic (see page 22), the unit will also automatically
select a quiet frequency avoiding any interference. The operator may also manually select frequencies.
Two test tags are included with the ORION 2.4. One is a semiconductor diode to simulate an electronic
device. The second is a steel wool pack, to simulate a corrosive metal-to-metal junction. These tags can
be used to verify the proper operation of the ORION 2.4.

There are two basic procedures to using any Non-Linear Junction Detector:

1. Detecting a non-linear junction and

2. Discriminating between electronics and false detection

The ORION 2.4 can be configured multiple ways to aid in these two processes.

APPENDIX

APPENDIX

The ORION 2.4, designed and built by the engineers at Research Electronics International, is the latest
advancement in Non-Linear Junction Evaluation. The ORION 2.4 can be used to locate electronic devices
whether in furniture, walls, ceiling fixtures or elsewhere. The ORION 2.4 detects semiconductor
junctions, to alert in the presence of electronics.

It is important to note that due to the variations in electronic circuitry, the unit will respond differently
to different electronic circuits. Therefore, the manufacturer makes no guarantee about the performance
of the unit when attempting to detect hidden electronic devices.

Background Theory

The ORION 2.4 radiates RF energy at frequency f0 and receives energy at 2f
signal at f0 encounters a non-linear junction, some of the energy is re-radiated back at f
the non-linear characteristic of the junction that generates 2f
respectively). By observing the presence of returned signals at 2f0, 3f0, the user can detect the presence
of a non-linear junction.

Where i is the current of the signal, Is the leakage current, q equals the electron charge, v is the voltage,
K equals Boltzman’s constant, and T is the temperature in Kelvins.

For small signals across the diodes terminals, we can reduce this to the first three terms,



In Eq. 3, the second term is responsible for generating the 2nd harmonic and the third term is responsible
for generating the 3rd harmonic.

Electronic devices typically have many different non-linear junctions (diodes, transistors, etc.) linked by
wires or printed circuit board traces. Therefore energy can be radiated in and out of the device through
complex paths. Typically the 2nd harmonic signal is stronger than the 3rd harmonic signal. However,
some circuits can re-radiate strong 3rd harmonic signals.

Other situations can also produce harmonic signals. Two dissimilar metals, joined or touching, and
corroded metals return harmonic signals (passive intermodulation). These we will refer to as false
junctions (Sometimes called “rusty bolt effect” or “environmental diodes”.)

APPENDIX

Semiconductor Junction

Characteristics

False Junction

Characteristics

The junctions in electronic devices and those in false junctions are quite different. The junctions in
electronic devices are well defined, but those created by false junctions are not as well defined or as
clean a physical junction. Imagine two perfect cubes joined—this would be a junction found in
electronic devices. False junctions are more like two irregularly shaped items touching in places, but not
in a smooth, regular pattern.

http://en.wikipedia.org/wiki/File:Rust_Bolt.JPG

Although there are various different types of semiconductor junctions (PN, PIN, JFET, MOSFET, etc.),
they all produce clean, predictable junction characteristics. For the junctions found in electronic devices,
this equation produces a predictable, but unsymmetrical curve. False junctions produce a less regular
curve, one that is noisy and unpredictable, yet they are typically symmetrical: their curve is mirrored for
negative values. The current/voltage characteristics are illustrated below.

31

APPENDIX

This level of regularity in the junction results in differences in the harmonic signals. When the
ORION 2.4 radiates a signal that is returned by the junction in electronics, it results in a strong 2nd
harmonic signal and a weak 3rd harmonic. A false junction returns a very weak 2nd harmonic and a
strong 3rd.

A B

ORION 2.4 COMPARISON OF HARMONIC LEVELS

(A – Semiconductor, B – False Junction; Bargraphs on the right are the 2nd and 3rd harmonic levels)

As mentioned earlier, some semiconductor circuits re-radiate a strong third harmonic signal. For
example with two diodes connected back to back (see below), the shape of the voltage curve resembles
the symmetry of a false junction and produces a stronger third harmonic than does a single diode.
