INTRODUCTION
DETECTIV is a sophisticated search tool integrating four
detection sensors to provide a more complete and robust
method of detecting electronic eavesdropping devices.
Four tried and tested detection methods: Harmonic receiver, broadband detector, Non-linear
junction detector and metal detector are integrated into one compact, easy to use unit.
Combining four complementary sensor systems together means more effective and efcient
search capability. With just one physical sweep of a target area four separate searches are carried
out. DETECTIV automatically switches between the four sensors using each detection method
in turn, ve times a second, allowing a continuous display of all detector activity.
Each sensor provides information which combines to provide a comprehensive picture of
any concealed targets. DETECTIV presents the multisensor information in a simple, easily
understood bar graph display. Additional expert screens give access to more detailed information
for each of the sensors. Using multiple detector information in this way improves detection and
gives more accurate identication between false alarms and real targets.
The Unit
The DETECTIV unit, shown opposite, is a hand-held case with a paddle shaped search head on
an extendable arm. Controls are grouped next to the handle for convenient thumb operation and
information is presented on a tilt-able TFT LCD touch-sensitive screen.
The input and output ports are grouped together under the tail of the unit along with the battery
compartment. The On /Off switch, audio output and headphone socket are conveniently located
at the top of the unit tail.
Handling
The extendable search head contains all the DETECTIV sensors and during a sweep search
needs to be passed close to all parts of a target area. Rotatable on two axis the head can be
twisted to provide the best attitude and position for searching most surfaces. The extendable arm
provides convenient access for the difcult to reach parts of a typical target area, for example,
ceilings and under desks. To minimise strain the unit has provision for a shoulder strap allowing
DETECTIV to be handled like a guitar and is designed to be balanced with the search head arm
extended approximately half way. The tail of the unit is also designed to provide a convenient
handle to control the unit when searching high surfaces.

Charging the battery
The DETECTIV battery packs are supplied without being charged. To operate the DETECTIV
you must rst charge the internal battery.
 Remove the battery door from the unit and insert the battery, (the end with the four
contacts goes in rst), into the battery compartment.
 Replace the battery compartment door and place the unit on charge by connecting an
appropriate AC/DC adaptor to the Charger socket. When successfully connected to a
live power supply the red LED next to the On/Off switch lights to indicate the battery
is being charged.
Note It is not necessary to switch DETECTIV On to charge the battery.
When the battery is fully charged, the red LED turns off and the green LED lights. The unit is now
ready for use.
Battery
The Internal rechargeable Lithium Ion battery pack gives approximately 2 hours continuous use;
Automatically recharged when external power is applied to the DETECTIV via an external AC/
DC Adaptor. Internal protection circuitry protects the battery. If for any reason the battery suffers
any transient fault such as short-circuit, overcharging or deep discharge, the pack will shutdown. It
will remain in this state until reactivated by connection of an external AC/DC Adaptor.
When the battery charge is low a battery icon is displayed on the display screen . This will
indicate there is approximately enough power to keep DETECTIV operating for a further 10
minutes. If the battery is completely exhausted the display will icker and fail.

DETECTIV User Manual
AUDIOTEL INTERNATIONAL MN400872 Issue 1 (08/04) 13
BASIC OPERATING METHODOLOGY The basic operating method for using the DETECTIV follows three sequential steps.
DETECT
With the DETECTIV displaying either the Main menu or the Detect display (Select DETECT
from the main menu) move the DETECTIV unit around the area to be secured.
Note DETECTIV is intended to nd suspicious devices within a target area. To avoid
excessive interference the sensors are optimised to limit the range at which
devices are detected. To search effectively the search head needs to pass closely
to all possible hiding places.
The DETECT mode utilises all the DETECTIV detectors simultaneously and should ensure that,
as the unit search head is swept over areas of likely concealment, the opportunities for detecting
a target are maximised.
When a large response is noted from one or more of the detectors it can be investigated further
using the Identify features for the appropriate detector.
IDENTIFY
The IDENTIFY stage involves using the various tools built into each one of the DETECTIV
detectors to try and identify whether or not the detected response is a possible threat.
If it seems likely that the detected response is a threat then the unit can move into the LOCATE
mode.
LOCATE
The LOCATE stage involves moving the DETECTIV around the suspect area using both the
display and the audio output to locate the source of the detected response.

AUDIOTEL INTERNATIONAL MN400872 Issue 1 (08/04) 15
From the Main menu select DETECT by either:
 Touch the DETECT icon on the screen
or
 use the Left and Right controls on the keypad to highlight the DETECT icon, then
press the  button to select.
The DETECT screen is displayed.
This is the basic mode of operation for the DETECTIV unit. In this mode all four detectors
are active at the same time. Each detector is designed to detect a specic type of target and is
represented with a vertical bar graph which increases or decreases in height in relation to the
detected signal(s).
The detectors are divided into 2 groups: Transmitter detectors and Device detectors
Transmitter Detectors
On the left of the screen these detectors respond to active radio transmissions.
Broadband CW will respond to continuous transmissions both narrow band (e.g. analogue
‘bug’) and broadband continuous transmissions (e.g. analogue video
transmissions)
Broadband Burst will respond to intermittent or burst transmissions (e.g. digital mobile
phones or frequency hopping devices)
Note because these two detectors are broadband in nature they only
indicate the strongest signal detected.
Harmonic Receiver will respond to continuous transmissions with better sensitivity than the
Broadband detectors, the harmonic receiver will also have the ability to
cancel out background signals and allow signals other than the strongest
signal to be captured.

Device Detectors
On the right of the screen these two detectors respond to electronic devices whether they are
active or inactive.
Metal detector will respond to inactive well screened metal targets with a reasonable cross
sectional area (6cm x 6cm) at a range of approx. 10cm through brick and
CELCON block.
NLJD will respond to electronic targets (active / inactive) provided they are not
well screened against the NLJD signals. The Bar graph display shows both
2nd (red) and 3rd (green) harmonic return signals
Selecting a Detector
To select a detector, either
 Touch the relevant detector icon on the screen
or
 use the Left and Right controls on the keypad to highlight the relevant detector icon.

Alternatively press the  control to deselect the sound selection.
Transmitter Detector Alarms
The transmitter detector bar graphs include alarm thresholds. These are indicated as red bars
across the vertical bar graphs.
To set an alarm threshold:
 select the relevant transmitter detector
 Use the UP and DOWN controls on the keypad to increase or decrease the alarm
threshold.

16 AUDIOTEL INTERNATIONAL MN400872 Issue 1 (08/04)
DETECTIV User Manual
AUDIOTEL INTERNATIONAL MN400872 Issue 1 (08/04) 17
When the level for any of the transmitter detectors exceeds the corresponding alarm threshold
the relevant bar graph will turn RED for approx. 5 seconds, this is accompanied by the alarm icon
for the relevant detector also being displayed in the top right hand corner of the screen also for
approx. 5 seconds.
If a multimedia card has been installed (see under Multi-media memory card in the Getting Started
part of this manual ) a time and date stamped entry of the alarm is also automatically registered in
the EVENT LOG (see the Event Log section later in this manual for further details).
NLJD Display
The NLJD bar graph shows two bars. These indicate the return signals received at the 2nd and
3rd harmonic frequencies.
The red bar indicates the 2nd harmonic signal and
the green bar shows the 3rd harmonic signal. The relative strengths of these two returns is used
as an indicator of the type of Non-Linear junction being detected.
Enabling / Disabling the NLJD
The TRIGGER control can be used to enable / disable the NLJD in both the DETECT screen and
the NLJD IDENTIFY screen.
To enable / disable the NLJD detector
