System Assembly & Startup: Section 2 on page 2 discusses in detail the step by step procedure for assembling the Conquest DE system and connecting the transducer module to it. Troubleshooting: Section 3 on page 5 presents some simple steps the user should go through when the transducer is not working as it should. Care and Maintenance: Section 4 on page 7 discusses procedures for the care and maintenance of your Conquest DE transducer module. 2-System Assembly Conquest DE Transducer Module System Assembly The modular design of the Conquest DE GPR makes the system very flexible and readily fieldportable. There are three essential components to the radar system: the transducer module, the Digital Video Logger (DVL) and an AC mains power source. The transducer module is connected to the DVL via the transducer cable and the power source is connected to the DVL (Figure 2-1). Power Cable AC Mains DVL Transducer Module Transducer Cable Figure: 2-1 Complete setup of the Conquest DE system. Conquest DE Transducer Module 2.1 2-System Assembly Connecting up the System Refer to Figure 2-1. a) Connect the Transducer Module to the female end of the Transducer Cable. Figure: 2-2 Connecting the Transducer Cable to the Transducer Module. b) Connect the male end of the Transducer Cable to the back of the DVL. c) Connect the Power Cable to the back of the DVL. d) Connect the 4 pin male end of the to Power Cable to AC Mains cable. When the DVL is receiving power the upper red LED on the front of the DVL will be illuminated. When the Transducer Module is receiving power the red and green LEDs will illuminate. e) Turn the DVL ON by pressing any button on the front. As the DVL boots up, the lower red light will come on. 2-System Assembly 2.2 Conquest DE Transducer Module Transducer Module Control Buttons The Transducer Module has a number of buttons on the top to control data collection. The 4 arrow buttons allow the operator to scroll up, down, left and right through menus on the display monitor (DVL or other) and the Enter button selects the current option. Left, Right, Up, Down Arrow Buttons Enter Button LEDs Star Button Odometer Wheel Speaker Figure: 2-3 Features of the Transducer Module. Conquest DE Transducer Module 3-Troubleshooting Troubleshooting The Transducer Module is designed to minimize user problems; however, all electronic devices are subject to possible failure. The following are troubleshooting hints if your system fails to operate. If the radar is not running properly, an error message will be displayed indicating the possible cause of the problem. Check Connections: If a problem occurs during system initialization, the first step is to check the connections. Make sure that cable connections are tight and that they have “clicked” into place. Reset the System by Powering Down: If the connections are OK but the error persists, try powering down the system completely. Then power everything back on and see if the system runs. 3.1 Power Supply Another common problem that can occur while trying to run a system is insufficient power. There may be a problem with the AC power supply or adapter. 3.1.1 DVL Power Requirements The DVL and pulseEKKO PRO control module are designed to operate from a 12 volt DC, 3 to 4 amp source such as batteries or AC Mains power supply. The input voltage tolerance is 10.2 volts to 15 volts. If there is enough power to run the DVL, the upper red LED on the front of the DVL will light up when the power source is plugged into the system. If this light is on and the DVL boots up, runs and displays the main menu then there is sufficient power for the DVL. If the voltage is less than about 10.2 volts, the DVL may not turn on and the upper red LED will flash or not illuminate. 3.1.2 Transducer Module Power Requirements The Transducer Module does not require a separate power source for operation. It is powered by the same 12 V battery that powers the DVL and Control Module (see above). Power is sent to the transducers through the transducer cable. 3.2 Transmitter Problem: No Signal on Screen If the pulse cannot be found do the following checks: 1) Make sure the system is properly powered and connected. 3-Troubleshooting Conquest DE Transducer Module 2) Check the condition of the transducer cable, looking for any signs of stress or damage. Replace or repair if needed. 3) Check that the pins at the connections of the transducer cable. Make sure that they are straight and clean to ensure proper contact. If the signal is still not found, contact Sensors & Software Inc. 3.3 Contacting Sensors & Software Inc. If you develop problems with your GPR system, contact your agent or Sensors & Software Inc. Sensors & Software Inc.’s hours of operation are 9:00 AM to 5:00 PM Eastern Standard Time, Monday to Friday.

Version number of the data acquisition software. The error number or message appearing. A brief description of when the error is happening and the operating conditions (temperature, humidity, sunshine, system and survey setup, etc.). Conquest DE Transducer Module 4.1 4-Care and Maintenance Care and Maintenance General To operate the Transducer Module equipment in a field environment, the user should exercise the normal care afforded other field instrumentation. Items that require specific maintenance procedures are listed below together with detailed descriptions of the procedures. The interior of the transmitter and receiver can become very hot very quickly if exposed to strong, direct sunlight. High temperatures can affect system electronics and may lead to failures. If a suspected heat failure does occur, stop the system and allow it to cool down before retrying. 4.2 Cable Care 1) The cable connectors as well as the connectors on the DVL need to stay clean and free of dust and moisture. Use a brush or air spray to clean dust, lint and other foreign particles from these connectors. 2) When the system is not being used, make sure the connections are done up to prevent dust and moisture from collecting inside. If the connectors are exposed, cover them with some sort of dust cap. 3) Cables are designed to be as tough as practical. 4) Careless use of cables making them carry loads that they are not designed for can cause internal damage. 5) Connectors are weak points in any system. With the use of this product in rough, dusty and outdoor environments, users can minimize potential down time if they care for cables and treat connectors with respect. 6) Cables and connectors are not designed to suspend or tow or otherwise carry the weight of systems. They are part of the electronic circuit and should be treated accordingly. When not in use they should be placed in their storage box. 4-Care and Maintenance Conquest DE Transducer Module Conquest DE Transducer Appendix A: Health & Safety Certification Appendix A: Health & Safety Certification Radio frequency electromagnetic fields may pose a health hazard when the fields are intense. Normal fields have been studied extensively over the past 30 years with no conclusive epidemiology relating electromagnetic fields to health problems. Detailed discussions on the subject are contained in the references and the web sites listed below. The USA Federal Communication Commission (FCC) and Occupational Safety and Health Administration (OSHA) both specify acceptable levels for electromagnetic fields. Similar power levels are mandated by corresponding agencies in other countries. Maximum permissible exposures and time duration specified by the FCC and OSHA vary with excitation frequency. The lowest threshold plane wave equivalent power cited is 0.2 mW/cm2 for general population over the 30 to 300 MHz frequency band. All other applications and frequencies have higher tolerances as shown in graphically in Figure A-1. Figure A-1: FCC limits for maximum permissible exposure (MPE) plane-wave equivalent power density mW/cm2. All Sensors & Software Inc. pulseEKKO, Noggin and Conquest products are normally operated at least 1 m from the user and as such are classified as “mobile” devices according to the FCC. Typical power density levels at a distance of 1 m or greater from any Sensors & Software Inc. product are less than 10-3 mW/ cm2 which are 200 to 10,000 times lower than mandated limits. As such, Sensors & Software Inc. products pose no health and safety risk when operated in the normal manner of intended use.

The objective is to assure that one apparatus or device does not interfere with any other apparatus or device in such a way as to make the other apparatus non-functional. Sensors & Software Inc. extensively test their pulseEKKO, Noggin and Conquest subsurface imaging products using independent professional testing houses and comply with latest regulations of the USA, Canada, European Community, and other major jurisdictions on the matter of emissions. GPR instruments are considered to be UWB (ultra wideband) devices. The regulatory regimes worldwide are devising new rules for UWB devices. Sensors & Software Inc. maintains close contact with the regulators to help guide standard development and assure that all products conform. You should continually monitor the "News" link on our website (www.sensoft.ca) for updates on standards. Electronic devices have not always been designed for proper immunity. If a GPR instrument is placed in close proximity to an electronic device, interference may occur. While there have been no substantiated reports of interference to date, if any unusual behavior is observed on nearby devices, test if the disturbance starts and stops when the GPR instrument is turned on and off. If interference is confirmed, stop using the GPR. Where specific jurisdictions have specific GPR guidelines, these are described below. B-1 Appendix B: GPR Emissions, Interference and Regulations B-1 Conquest DE Transducer FCC Regulations This device complies with Part 15 of the USA Federal Communications Commission (FCC) Rules. Operation in the USA is subject to the following two conditions: (1) this device may not cause harmful interference and (2) this device must accept any interference received, including interference that may cause undesired operation. Part 15 – User Information This equipment has been tested and found to comply with the limits for a Class A digital device, where applicable, and for an ultrawide bandwidth (UWB) device where applicable, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. WARNING Changes or Modifications not expressly approved by Sensors & Software Inc. could void the user’s authority to operate the equipment. Certification of this equipment has been carried out using approved cables and peripheral devices. The use of non-approved or modified cables and peripheral devices constitutes a Change or Modification outlined in the warning above. Operating Restrictions Operation of this device is limited to purposes associated with law enforcement, fire fighting, emergency rescue, scientific research, commercial mining, or construction. Parties operating this equipment must be eligible for licensing under the provisions of Part 90 of this chapter. FCC Interpretation of Operation Restrictions issued July 12, 2002 (FCC Order DA02-1658, paragraph 9) The regulations contain restrictions on the parties that are eligible to operate imaging systems. 1 Under the new regulations, GPRs and wall imaging systems may be used only by law enforcement, fire and emergency rescue organizations, by scientific research institutes, by commercial mining companies, and by construction companies. Since the adoption of the Order, we have received several inquiries from the operators of GPRs and wall imaging systems noting that these devices often are not operated by the users listed in the regulations but are operated under contract by personnel specifically trained in the operation of these devices. We do not believe that the recent adoption of the UWB rules should disrupt the critical safety services that can be performed effectively only through the use of GPRs and wall imaging systems. We viewed these operating restrictions in the broadest of terms. For example, we believe that the limitation on the use of GPRs and wall imaging systems by construction companies encompasses the inspection of buildings, roadways, bridges and runways even if the inspection finds no damage to the structure 1. See 47 C.F.R. §§15.509(b), 15.511(b), and 15.513(b) B-2 Conquest DE Transducer Appendix B: GPR Emissions, Interference and Regulations and construction does not actually result from the inspection; the intended purpose of the operation of the UWB device is to determine if construction is required. We also believe that the GPRs and wall imaging systems may be operated for one of the purposes described in the regulations but need not be operated directly by one of the described parties. For example, a GPR may be operated by a private company investigating forensic evidence for a local police department. FCC Permitted Mode of Usage The GPR antenna must be kept on the surface to be in compliance with FCC regulations. Use of the antenna is not permitted if it is lifted off the surface. Use as a through-the-wall imaging device is prohibited. GPR Use Coordination FCC regulation 15.525(c) requires users of GPR equipment to coordinate the use of their GPR equipment as described below: a) UWB imaging systems require coordination through the FCC before the equipment may be used. The operator shall comply with any constraints on equipment usage resulting from this coordination. b) The users of UWB imaging devices shall supply operational areas to the FCC Office of Engineering and Technology, which shall coordinate this information with the Federal Government through the National Telecommunications and Information Administration. The information provided by the UWB operator shall include the name, address, and other pertinent contact information of the user, the desired geographical area(s) of operation, and the FCC ID number and other nomenclature of the UWB device. If the imaging device is intended to be used for mobile applications, the geographical area(s) of operation may be the state(s) or county(ies) in which the equipment will be operated. The operator of an imaging system used for fixed operation shall supply a specific geographical location or the address at which the equipment will be operated. This material shall be submitted to the following address: Frequency Coordination Branch., OET Federal Communications Commission 445 12th Street, SW Washington, D.C. 20554 ATTN: UWB Coordination The form given on the following page is a suggested format for performing the coordination.

Details on individual country requirements for licensing are coordinated with this standard. For more information, contact Sensors & Software’s technical staff. B-5 Conquest DE Transducer Appendix B: GPR Emissions, Interference and Regulations B-6 Conquest DE Transducer Appendix C: Appendix C: Instrument Compatibility Instrument Compatibility Immunity regulations place the onus on instrument/apparatus/device manufacturers to assure that extraneous interference will not unduly cause an instrument/apparatus/device to stop functioning or to function in a faulty manner. Based on independent testing house measurements, Sensors & Software Inc. systems comply with such regulations in Canada, USA, European Community and most other jurisdictions. GPR devices can sense electromagnetic fields. External sources of electromagnetic fields such as TV stations, radio stations and cell phones, can cause signals detectable by a GPR which may degrade the quality of the data that a GPR device records and displays. Such additive signal is unavoidable but sensible survey practice and operation by an experienced GPR practitioner can minimize such problems. In some geographic areas emissions from external sources may be so large as to preclude useful measurements. Such conditions are readily recognized and accepted by the professional geophysical community as a fundamental limitation of geophysical survey practice. Such interference being present in the GPR recordings is not considered as an equipment fault or as a failure to comply with immunity regulations. C-1 Appendix C: Instrument Compatibility Conquest DE Transducer C-2 Conquest DE Transducer Appendix D: Safety Around Explosive Devices Appendix D: Safety Around Explosive Devices Concerns are expressed from time to time on the hazard of GPR products being used near blasting caps and unexploded ordnance (UXO). Experience with blasting caps indicates that the power of Sensors & Software Inc.’s GPR products are not sufficient to trigger blasting caps. Based on a conservative independent testing house analysis, we recommend keeping the GPR transmitters at least 5 feet (2m) from blasting cap leads as a precaution. Some customers do experimental trials with their particular blasting devices to confirm with safety. We strongly recommend that GPR users routinely working with explosive devices develop a systematic safety methodology in their work areas. The UXO issue is more complex and standards on fuses do not exist for obvious reasons. To date, no problems have been reported with any geophysical instrument used for UXO. Since proximity and vibration are also critical for UXO, the best advice is to be cautious and understand the risks. D-1 Appendix D: Safety Around Explosive Devices Conquest DE Transducer D-2
