Be sure to verify the contents shown on the packing list and inspect the equipment for any loose parts or other damage. All packing material should be preserved in the event that any damage occurred during shipping. Any claims for shipping damage should be filed to the carrier. Any claims for missing equipment or parts should be filed with Mala GeoScience. 1.2 Repacking and Shipping If original packing materials are unavailable, the equipment should be packed with at least 80 mm of absorbing material. Do not use shredded fibers, paper wood, or wool, as these materials tend to get compacted during shipment and permit the instruments to move around inside the package. 4 2 Start up and Hardware Description ___________________________________________________________ The RAMAC X3M/EasyLocator is an integrated radar control unit, mounted directly on the shielded antennas and powered externally. X3M is compatible with the RAMAC/GPR shielded antennas 100, 250, 500 and 800MHz. EasyLocator has it own family of shielded antennas; DEEP, MID and SHALLOW. The built-in electronic design makes it a low weight and compact size system, easier to assemble and operate. No fiber optic cables are required since the unit communicates directly with the laptop. Based on the flexibility and the modularity of the RAMAC/GPR, the RAMAC X3M is fully compatible with the Windows based acquisition software Ground Vision, while the EsayLocator has it own acquisition software: EasyVision. The built-in default autostacking function secures the best data quality at maximum survey speed, in both units. This section will give a short overview of how the GPR (Ground Penetrating Radar) systems work. 2.1 Layout of the RAMAC X3M /EasyLocator Figure 2.1a. Layout of the X3M The different number in Figure 2.1 corresponds to the following: 1: Connector for kill switch 2: Power button 3: Connector for encoder, 9 pin d-sub (wheel or hip chain) 4: Connector for parallel cable to a PC, 25 pin d-sub 5: Securing screws for mounting on antennas 6: Power cable connection Figure 2.1.

ON/OFF 6 2.3 Power cable When the X3M/EasyLocator is mounted on the antenna connect the Power cable from your battery. Look for the countersink and place it towards the mark on the connection. Push lightly. If you have it in the correct position it should connect smoothly. To disconnect: Pull out, holding the milled part of the connection. 2.4 Distance measuring devices The X3M/EasyLocator can be used together with the standard MALÅ GeoScience distance measuring devices (hip-chain and measuring wheels). The encoder cable is connected as shown below (Figure 2.4) 2.5 Connection to computer Add the computer to the system by connecting the parallel port cable between the computer and the X3M/EasyLocator (Figure 2.5). Use an IEEE 1284 compatible parallel cable that is less than or equal to three meters long. Figure 2.4. Encoder Figure 2.3. Power cable Figure 2.5. Parallel port 7 2.6 Kill switch The kill switch is attached to a handle that can either be handheld or snapped onto a RAMAC/GPR Cart (Figure 2.6 top). The X3M/EasyLocator will not be operational without the kill switch. The button has to be pushed down at all times during measurements. If the button is released the transmitter will stop transmitting. Connect the kill switch to the bayonet holder on the X3M/EasyLocator by pushing lightly and turning the bayonet socket clockwise (Figure 2.6 bottom). To disconnect: Turn the bayonet socket counterclockwise and pull out. 2.7 Start up and power button To start the X3M/EasyLocator press and hold the start button for approximately two seconds. The light in the center of the button will start to flash (Figure 2.7). Next start the acquisition software, GroundVision or EasyVision, in your computer. During t…

Fletcher, Heald & Hildreth, P.L.C. 1300 North 17 th Street 11 th floor Arlington VA 22209 703-812-0400 (voice) 703-812-0486 (fax) MITCHELL LAZARUS 703-812-0440 [email protected] February 26, 2004 Mr. Edmond J. Thomas Chief, Office of Engineering and Technology Federal Communications Commission 445 12th Street SW Washington DC 20554 Re: Certification Applications FCC ID QLA100MHZ EA546722 Dear Mr. Thomas: The above-referenced applications, filed by Mala GeoScience AB, seek certifications for ground-penetrating radar (GPR) devices. The applications show compliance with the Commission's Rules and do not require waivers. We request that certain photographs showing the interior of the devices be withheld from public disclosure. The Commission has previously granted confidentiality under the same conditions to the following applications: FCC ID QLA250MHZ EA586775 FCC ID QLAMID EA364767 FCC ID QLA500MHZ EA369105 FCC ID QLA800MHZ EA813498 Factual Basis for Confidentiality Request Ordinarily the Commission denies confidentiality to photographs of a device on the ground that the information they contain is freely available to a competitor, simply by purchasing the device and (if necessary) unscrewing the cover. But the devices in question are different. The interior is sealed, and its appearance is inaccessible to the purchaser. To gain access to the views shown the interior photographs, a competitor would have to purchase the device and then carry out the following steps: 1. Use a drill to dismantle all the rivets securing the cover. A competitor has no way of knowing the correct drill size, or where to begin dismantling. Mr. Edmond J. Thomas February 26 , 2004 Page 2 Use of the wrong drill, or starting with the wrong rivets, will require replacing all mechanical parts. 2. Destroy the loading of the transmitter. Absorbers are glued to the transmitter elements and cannot be removed undamaged. The antenna flares are connected to the RF absorbers, as well as to the metallic shields with thin layers of absorbers glued in place. These strips cannot be loosened without destroying them. A competitor is unlikely to have access to the right material, or even to know what grade of materials to use. 3. Use a screwdriver to dismantle the shields and the top plate. 4. De-solder the sampler head, so as to remove the electronics. But high- performance, temperature-sensitive Schottky bridges are placed directly at the soldering point connecting the sampler head to the preamp transmission line. Efforts to remove the electronics are thus likely to cause serious damage. Mala Geoscience has never released instructions on how to disassemble its units, and does not answer questions on how to do so. This information is kept internal to the company. If a unit arrives at the company's repair facility showing evidence of such tampering, the company does not repair it, but charges the customer for a new unit plus freight costs. The Commission's posting of the photographs would allow a competitor to bypass this difficult and expensive disassembly. From the photographs, a competitor can estimate: 1. the costs of manufacturing of the breadboards and mechanical housing; 2. the man-hours required to assemble the device; 3. any compatibility problems the manufacturer will have in designing new systems; and 4. the age of the electronic design (which gives valuable competitive information on upgrade and R&D efforts). Interior photographs that comply with the Commission's requirements would almost permit a competitor to conduct a complete reverse engineering, to the point of producing a schematic. Mr. Edmond J. Thomas February 26 , 2004 Page 3 We respectfully submit that manufacturers should not be required to hand over to competitors the fruits of years of expensive engineering. Legal Basis for Request The Freedom of Information Act (FOIA) protects from disclosure "commercial or financial information obtained from a person and privileged or confidential." 1 Information is confidential if it is "the kind of information 'that would customarily not be released to the public by the person from whom it was obtained,'" 2 and would cause "substantial harm to the competitive position of the person from whom the information was obtained." 3 The D.C. Circuit in Worthington Compressors addressed the specific issue underlying the present request: the "additional wrinkle that the requested information is available, at some cost, from an additional source." 4 Here, of course, the "additional source" is the acquisition and destruction of a specimen unit, and the cost is that of repairing or replacing it following access to the interior. According to the Worthington court, availability of the information through alternate sources triggers two additional inquiries: (1) the commercial value of the information, and (2) the cost of acquiring the information through the other means. 5 The court acknowledges that the submitting party can suffer competitive harm if the information has commercial value to competitors. 6 That is the case here. As explained above, the interior photographs disclose a great deal of expensive (and proprietary) engineering. 1 5 U.S.C. Sec. 552(b)(4). 2 McDonnell Douglas Corp. v. NASA, 180 F.3d 303, 304-05 (D.C. Cir. 1999), quoting Critical Mass Energy Project v. NRC, 975 F.2d 871, 879 (D.C. Cir. 1992) (en banc). See also Nat'l Parks & Conservation Ass'n v. Morton, 498 F.2d 765, 770 (D.C. Cir. 1974). 3 Worthington Compressors, Inc., v. Costle, 662 F.2d 45, 51 (D.C. Cir. 1981), citing National Parks & Conservation Ass'n v. Morton, 498 F.2d 765, 770 (D.C.Cir.1974). 4 Id. (italics in original). 5 Id. (italics in original). 6 Id. Mr. Edmond J. Thomas February 26 , 2004 Page 4 Once commercial value is established, the court turns next to the cost of acquiring the information by means other than agency disclosure. If competitors "can acquire the information [by other means] only at considerable cost, agency disclosure may well benef…

Re: FCC ID QLA100MHZ Applicant: Mala GeoScience AB (publ) Correspondence Reference Number: 26606 731 Confirmation Number: EA546722 1. What is the pulse width? As can be seen in the figure below, the pulse with is approximately 6ns, measured with a small antenna probe, in air. 2. Internal and external photo's of the transmitter X3M unit. The X3M unit is not part of the UWB-transmitter. Nevertheless, external photos on this unit were filed in the original filing and internal photos have been uploaded on your web. 3. Provide a block diagram that shows the frequencies, signal path, oscillators per 2.1033(b)5. 2.1033(b)5 is actually not applicable in this case since this isn’t a radio receiver with oscillators, mixers and tuned stages. This is a digital system with one crystal controlled oscillator (7.94 MHz)and a frequency divider, all mounted in a shielded metal box. 4. A letter of approval for the request of confidentiality. A confidential request as well as motivation for it has been filed. So far we have not received any answer on this, please advice.
