ANDRE Packages
The ANDRE is available in three packages (Basic, Advanced, and Deluxe) with varying probes, antennas,
and accessories. Below is a chart showing which probes, antennas, and accessories are included in each
package (note that this is subject to change). Additional information can be found in the Probes,
Antennas, and Accessories section on the following pages.
EQUIPMENT DESCRIPTION
12
Probes, Antennas, and Accessories
Whip / Dipole Antenna (30MHz - 6 GHz)
The Whip / Dipole is a general purpose, omnidirectional, near-field probe used for locating RF
transmitters up to 6 GHz.
Concealed Antenna (750 MHz - 6 GHz)
The Concealed Antenna is omnidirectional and is used for covert detection of devices. When the
concealed antenna is connected, the ANDRE will automatically switch to Covert Mode. This mode could
be used to conduct a covert search by connecting the concealed antenna and then hiding the unit in, for
example, a jacket pocket, walking around the room and relying on the haptic feedback for alerts. Covert
mode automatically disables any alerting features. It turns the speaker off, enables haptic feedback
mode, and shuts off the display and the power LED.
Locator Probe (20 MHz - 6 GHz)
The Locator Probe is an omnidirectional probe and is attenuated for use in high RF environments and for
locating an RF signal within a few inches.
EQUIPMENT DESCRIPTION
13
VLF Loop Antenna (10 kHz - 30 MHz)
The VLF Loop Antenna is an omnidirectional antenna used for locating low frequency signals below 30
MHz.
Acoustic Leakage Detector (ALD)
With the Acoustic Leakage Detector, the operator can determine the vulnerability of acoustic leakage by
placing the probe against structural objects such as walls or windows. The Acoustic Leakage Detector
connects to the Audio Input on the ANDRE.
Audio Transformer (300 Hz - 20 kHz)
The Audio Transformer is a balanced audio coupler to
provide electrical isolation for audio testing. A 3.5 mm
Stereo to 3.5 mm Stereo cable is included with the
ANDRE to connect the audio transformer to the ANDRE.
Two push buttons provide positive and negative bias
voltage to the two banana jacks on the audio
transformer. The control knob on the audio transformer
adjusts the level of the applied bias voltage from 0 to 22
volts. An included set of banana jack test leads with bed-
of-nail alligator clips allow the audio transformer to be
used on 66 blocks or other wires.
EQUIPMENT DESCRIPTION
14
Carrier Current Probe (100 kHz to 60 MHz)
The Carrier Current Probe can be used to test for carrier current signals on any pair
of conductors less than 250 volts. Before testing an unidentified pair of power
conductors, a voltmeter should be used to measure the voltage across the
conductors. If this voltage exceeds 250 volts, do not test with the Carrier Current
Probe. Two power plugs are included for connection to US style or Euro style
outlets. The included alligator clip cable assembly should only be used on 50V or
less. Measurements can be made with three different pair configurations using the
switch on the front of the carrier current probe: Hot/Neutral, Neutral/Ground, and
Hot/Ground.
Due to power line noise and the broad frequency range that ANDRE searches, every outlet in an area
should be inspected.
Note: the frequency counter is disabled when using the Carrier Current Probe and the operator should
rely on the detected signal strength when using the carrier current probe. No frequency will be
displayed while using the Carrier Current Probe, nor will any signals be added to the signal list.
Log Periodic Antenna (500 MHz - 6 GHz)
The directional antenna is a log periodic antenna which can be used for improved detection in the 500
MHz to 6GHz range.
EQUIPMENT DESCRIPTION
15
Directional Antenna (70 MHz - 500 MHz)
This flag-shaped antenna provides directional coverage for lower frequency signal detection. It is a
powered probe and must be used with one of the powered connector cables (see page 33).
Down Converter Directional Antenna (500 MHz - 12 GHz)
The Down Converter Antenna is a directional antenna that operates in two user selectable bands (see
page 34):
Band 1: 500 MHz – 6 GHz
Band 2: 6 GHz – 12 GHZ
When using Band 2, the Down Converter Antenna converts signals occurring above the standard 6 GHz
threshold so they can be detected and displayed on the ANDRE. For details on operation, see page 34.
EQUIPMENT DESCRIPTION
16
The down converter antenna is a powered probe and must be used with one of the powered
connector cables (see page 34).
Ultrasonic Probe (15 kHz - 80 kHz)
The ultrasonic probe detects sound waves operating above the upper limit of human hearing
capabilities. The ultrasonic probe connects to the ANDRE with the provided audio patch cable. For
details on Ultrasonic probe operation see page 34.
Nitecore Dual Bay Battery Charger
The Dual Bay Battery Charger allows the user to externally charge two of the ANDRE Lithium Ion
batteries.
Note: The Dual Bay Battery Charger is available with the ANDRE Advanced and Deluxe models. It can
also be purchased separately by contacting REI or an Authorized REI reseller.
OPERATION
17
OPERATION
The ANDRE has been designed for quick and easy deployment. Depending on your application some
adjustments to the default setting may need to be made.
The ANDRE is a broadband RF detector and is used to locate transmitters by monitoring the RF signal
strength. When searching for unknown transmitters, it is advised to remove or disable any known
transmitters from the target sweep area (i.e. unplug, turn off, or remove any wireless transmitting
devices including Wi-Fi and Bluetooth devices, laptops/PCs, mobile phones, wireless transmitting
devices, etc.), as any transmitting devices can affect the RF noise floor and hinder detection of unknown
transmitters.
Also, the process of connecting a probe or changing the settings on the ANDRE may cause inaccurate
signal levels or other abnormal behavior and may result in the addition of unwanted, invalid signals to
the signal list. REI recommends the following process for using the ANDRE in a sweep:
1. Configure the ANDRE for use (set attenuation/gain, adjust trigger level, set chart audio, set
haptic style, etc…)
2. Connect a probe and confirm correct input source.
3. Clear the signal list (see page 25) and data log (if enabled) (see page 43).
4. Begin sweep.
Battery Usage
Lithium-Ion rechargeable batteries have been included with your unit. The ANDRE will operate with just
one charged battery inserted; however, use two batteries for the longest run time.
To insert or switch out a new battery:
1. Locate the battery door on the back of the unit.
OPERATION
18
2. Using both thumbs, slide the battery door open in the directions of the arrows engraved in the
plastic. The battery door will slide open just a couple of millimeters, but can then be flipped up.
3. Labels inside the battery compartment indicate the correct polarity of the batteries.
4. After inserting the batteries, close the battery door by flipping it back down and sliding the
battery door back in the opposite direction of the arrows.
The ANDRE has a built-in battery charger. To charge the battery in the unit:
1. Locate the included AC adapter and USB cable. Connect the USB cable to the AC adapter.
2. With the battery already inserted in the unit, connect the AC adapter to an AC source and the
USB cable end to the USB Port on the ANDRE. The battery will begin charging. Charging is
automatic; it will stop when the battery is fully charged. While the battery is charging, the
power LED will flash green; the flash rate will be proportional to the charge level.
Note: To keep the batteries in good working condition, they should be removed from the ANDRE for
long term storage of 90 days or more. Even when powered off, the operating system of the ANDRE
continues to use a low stand-by current that in some cases could cause a deep discharge and possible
damage to the battery, preventing a normal recharge. To extend battery life it is recommended that the
batteries are charged every three months when unused for long periods.
OPERATION
19
Included with the ANDRE Advanced and Deluxe models is a Dual Bay Battery Charger. To use this
external battery charger:
1. Unwind the connected USB cable from the charger base.
2. Flip the battery charger over and flip the base up. Remove the USB A connector from this port.
3. Connect the USB micro end of the cable into the port on the side of the charger. Connect the
USB A end to the included AC power adapter, a PC, or other standard USB output port.
4. Insert the batteries to be charged being sure to observe the polarity markings on the charger.
5. After battery installation, the charger will run a quick battery test before charging. If a problem
is detected (for example, the batteries are installed backwards), charging will stop and "EE" will
be displayed on the LCD to notify the user.
6. When batteries are fully charged, 5 power level indicator bars and "100%" will illuminate steady
on the LCD display.
Two or more external battery chargers can be serially-connected together to perform cascade charging;
as one set of batteries finishes charging, the second set will automatically begin charging. To perform
cascade charging:
1. Connect the first charger in the chain to a power source using the steps above.
2. Take a second USB A to USB micro cable and connect the USB A end to the charging port under
the base of the first charger.
3. Connect the USB micro end of the 2
nd
cable to the USB micro port on the side of the 2
nd
battery
charger.
4. The switch labeled "USB Battery" on the side of charger determines the charging priority. If the
switch on the first charger is set to "Battery", the charger will first charge the inserted batteries.
Once the inserted batteries are at full charge, the device will automatically begin charging the
batteries inserted in the downstream charger. If the switch on the first charger is set to "USB",
then the batteries in the downstream charger will charge first. Once these are at full charge,
then charging will switch to the batteries inserted in the first charger.
OPERATION
20
Audio Transformer Batteries
The audio transformer, which is an accessory probe included with the ANDRE Advanced and Deluxe
models, requires two A23C batteries, which are customer replaceable.
To replace the audio transformer batteries:
1. Using a Phillips head screwdriver, remove the two screws from the back of the audio
transformer.
2. Locate the two A23C batteries and replace, being careful to observe the polarity marked on the
unit.
OPERATION
