6 AUDIOTEL INTERNATIONAL MN400872 Issue 1 (08/04) DETECTIV User ManualAUDIOTEL INTERNATIONAL MN400872 Issue 1 (08/04) 7INTRODUCTIONDETECTIV 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 UnitThe 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.HandlingThe 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.

8 AUDIOTEL INTERNATIONAL MN400872 Issue 1 (08/04) DETECTIV User ManualAUDIOTEL INTERNATIONAL MN400872 Issue 1 (08/04) 9Charging the batteryThe 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.BatteryThe 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.Inserting the batteryConnecting an AC/DC adaptor

DETECTIV can be operated without a multimedia memory card installed although you will be unable to save screen shots or any log records. Note DETECTIV should be off when a ash memory card is inserted into the memory card slot. The contacts on the memory card should be facing away from the accessory socket when inserting the Mulitmedia card.The number of screen Snapshots that can be stored is displayed in a Snapshot counter sc in the upper section of the display on all DETECT and IDENTIFY screens. If no memory card is installed the Snapshot counter is crossed out in red sc .Switching the unit ON (and Off) To switch the unit ON press and hold the ON / OFF switch for a second or two. The Unit performs an initialising sequence displaying the message 'Please Wait'. Note During the initialising sequence the various detectors are calibrated. To ensure the best performance from DETECTIV the search head should be kept clear of any potential targets during this calibration.Once the initialising sequence is completed the Main Menu is displayed. To switch the unit OFF press and release the On/Off switch. The back light will turn off immediately although a residual image may linger on the screen for a few moments.Inserting a memory cardCard contacts on side away from accessory socket
10 AUDIOTEL INTERNATIONAL MN400872 Issue 1 (08/04) DETECTIV User ManualAUDIOTEL INTERNATIONAL MN400872 Issue 1 (08/04) 11Using the controls and selecting optionsTo navigate around the various screens and select options a combination of keypad controls and on-screen buttons are used. ControlsThe navigation controls are arranged up, down, left and right in the centre of the keypad. Their use depends on the current screen and the screen item selected. Usually the left and right controls change the current selection left or right and the up and down controls adjust levels (alarm levels, power levels, etc.) The  control is primarily used to toggle between setting the sound volume and the current selection. Sound volume can only be set on those screens that display the sound icon in the DETECT and IDENTIFY modes (see under Setting the Unit volume in the DETECT mode section of this manual).. Note On those screens where setting the sound volume is not applicable, for convenience, this control also duplicates the most common screen option.The 3control is used to return back up to the parent screen of the current screen.The p control is used in the IDENTIFY mode to pause the display and capture screen images for later analysis. Press p once to Pause the display ' >>> P a u s e d <<< ' appears on the screen display press p a second time to save a screen shot to the Snapshot Log To cancel the Pause press the 3control.Screen OptionsThe touch sensitive screen is used to select items in the main menu and choosing a detector in the Detect screen as well as operating various screen buttons that appear at the bottom of the screen. The NLJD Trigger control is used to turn the NLJD On or Off. (See under Enabling /Disabling the NLJD later in this manual).

12 AUDIOTEL INTERNATIONAL MN400872 Issue 1 (08/04) DETECTIV User ManualAUDIOTEL INTERNATIONAL MN400872 Issue 1 (08/04) 13BASIC OPERATING METHODOLOGY The basic operating method for using the DETECTIV follows three sequential steps.DETECTWith 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.IDENTIFYThe 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.LOCATEThe 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.
14 AUDIOTEL INTERNATIONAL MN400872 Issue 1 (08/04) DETECTIV User ManualAUDIOTEL INTERNATIONAL MN400872 Issue 1 (08/04) 15From 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 DetectorsOn 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.DETECT MODEDETECT mode iconDetector selectionIndicator bar graphsSound Volume (see under setting the unit Volume)Snapshot counterHarmonic receiver mode indicator Alarm icons appear hereIDENTIFY mode button LOCATE mode button
14 AUDIOTEL INTERNATIONAL MN400872 Issue 1 (08/04) DETECTIV User ManualAUDIOTEL INTERNATIONAL MN400872 Issue 1 (08/04) 15Device DetectorsOn 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 signalsSelecting a DetectorTo 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.The currently selected detector is identied in the upper part of the DETECT screen and highlighted by a RED box around the detector icon.

This increases or decreases the rate at which the display scrolls.The audio output in this mode is broadband AM. Alarm thresholds remain active in this mode and can be adjusted using the up and Down controls. When the alarm threshold is exceeded the appropriate alarm icon is displayed in the top right hand corner of the display and an entry is made in the EVENT LOG. In addition this mode also compares the received signals against a library of known signal signatures. If the signal is recognised the signal type (e.g.: GSM) is also displayed in the top left hand side of the screen.
20 AUDIOTEL INTERNATIONAL MN400872 Issue 1 (08/04) DETECTIV User ManualAUDIOTEL INTERNATIONAL MN400872 Issue 1 (08/04) 21Harmonic Receiver IDENTIFY screenThe Harmonic Receiver Identify screen displays the radio frequency spectrum in a compressed form. To change the span of the Spectrum displayed use the Zoom In and Zoom Out on-screen buttons. The current zoom level is indicated in the upper part of the screen above the spectral display.As in the broadband Identify screens the Alarm thresholds remain activeListening to a captured radio signal - Auto TuningWhen Auto Tune is selected the cursor (and hence the listening receiver) is automatically tuned to the highest level signal on the screen. To turn Auto tuning On or Off press the Auto Tune on-screen buttons. Auto tune is ON when the button appears down (the Auto Tune text appears black) and the tuning cursor is displayed in blue. Note Manual tuning is inactive in Auto Tune.Manual TuningThe audio output for the Harmonic Receiver Identify stage is FM (Frequency Modulation). The actual signal being listened to is identied with green tuning cursor cross-hairs. To select a particular signal to listen to either: Touch the display screen on the required signal peak or  Use the LEFT and RIGHT controls to move the cursor left or right respectively.The cursor can also be dragged using a nger to drag across the touch screen Note: The harmonic receiver captures the RF spectrum (10MHz to 10GHz) in four bands (approx. 2.5GHz wide), therefore when scanning rapid clicking will be heard as the receiver switches through the bands in sequence.
20 AUDIOTEL INTERNATIONAL MN400872 Issue 1 (08/04) DETECTIV User ManualAUDIOTEL INTERNATIONAL MN400872 Issue 1 (08/04) 21 To improve the audio quality of a captured radio signal press the P control on the keypad to pause the receiver. This pauses the receiver on the band of the captured signal. The background clicking will know cease and the audio quality will improve.Scanning in DIFFERENCE modeThe Diff On on-screen button selects and deselects the Difference mode. Difference mode is ON when the Diff On button appears down (the Diff On text appears black) .When Difference mode is selected the current scan display is stored as a reference scan, all subsequent scans are compared with this reference scan and the differences between the two are displayed. This allows the user to take a scan of background RF activity prior to entering the target area and effectively cancelling out background signals from the display. This will help in highlighting signals peculiar to the target area that will require investigation.Previous scans from a target area can also be used as reference scans allowing changes in RF activity between sweeps to be highlighted quickly. These stored reference scans are captured when the p control is used and held in the EVENT LOG - reference list. Uploading stored scans is covered later in this manual in the EVENT LOG section.Measuring a signal frequency Note This facility is only available in Spectrum mode with Auto Tune selected.To measure the frequency of a captured radio signal Press the p control on the keypad.This pauses the display and also attempts to measure the real RF frequency of the signal indicated by the blue cursor cross-hairs. The value is displayed above the main spectrum display. Note DETECTIV takes four measurements. The result is only displayed if a consistent result is obtained in three of the four attempts.
