Overview - 4 2450GR Operator’s ManualOverviewCMW3. Antenna Digital radar transmitter/receiver that uses two frequencies to detect buried pipes. High frequency (700MHz) has shallow penetration. Best in conditions with good radar conductivity, such as ice, sand, concrete, or rock. Low frequency (250 MHz) has broad, deep penetration. Better in conditions with poor radar conductivity, such as clay, salt, or wet soil.The 2450GR scans and records both frequencies simultaneously at all times. 4. Battery Provides 12V DC to control unit. Recharge when battery drops below 10V, or as indicated by acquisition software. 5. Wheel position sensorMeasures the distance traveled by the cart. Located in the left rear wheel. 6. Control Unit Receives data from the antenna and the wheel position sensor and translates it to the tablet PC. 7. Battery Charger To recharge battery, connect charger to battery. Allow about 3 hours for battery to charge. Item Description Notes
2450GR Operator’s Manual Overview - 5Intended UseCMWIntended UseThe 2450GR is a ground penetrating radar system that detects metallic and non-metallic pipes and cables buried underground. Following standard radar principles, the 2450GR uses a high performance electromagnetic sensor equipped with electromagnetic transmitters and recievers to identify underground utilities and transmit the location data to a portable computer where specialized software maps the location site. The unit is designed for operation in conditions typically experienced in earth moving and construction work environments. Provisions may be required to operate in extreme temperatures. Use in any other way is considered contrary to the intended use. The 2450GR should be used with genuine Subsite Electronics components. It should be operated, serviced, and repaired only by persons familiar with its particular characteristics and acquainted with the relevant safety procedures.Any changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment.This equipment is sensitive to the presence of external electromagnetic fields, which may reduce its performance.About This ManualThis manual contains information for the proper use of this machine. Cross references such as “See page 50” will direct you to detailed procedures.Bulleted ListsBulleted lists provide helpful or important information or contain procedures that do not have to be performed in a specific order.Numbered ListsNumbered lists contain illustration callouts or list steps that must be performed in order.

The FCC/NTIA coordination report shall identify those geographical areas within which the operation of a 2450 GR requires additional coordination or within which the operation of a 2450 GR is prohibited. If additional coordination is required for operation within specific geographical areas, a local coordination contact will be provided. Except for operation within these designated areas, once the information requested on the 2450 GR is submitted to the FCC no additional coordination with the FCC is required provided the reported areas of operation do not change. If the area of operation changes, updated information shall be submitted to the FCC following the procedure in paragraph (b) of this section.The coordination of routine UWB operations shall not take longer than 15 days from the receipt of the coordination request by NTIA. Special temporary operations may be handled with an expedited turn-around time when circumstances warrant. The operation of the 2450 GR system in emergency situations involving the safety of life or property may occur without coordination provided a notification procedure, similar to that contained in CFR 47, Section 1.405(a) through (e) is followed by the equipment user.WARNING: this equipment is designed for use in industrial environments (Class A apparatus). This apparatus generate radio interference in residential, commercial and light industry environments and the user may be required to take appropriate countermeasures during operation.

Prepare - 30 2450GR Operator’s ManualSurvey the SiteCMWSurvey the SiteConsider the following when preparing to work at a survey site:• Gain permission to access pedestrian zones, interrupt traffic flow, etc.• Determine site accessibility.• Determine space available for cart.• Observe traffic levels.• Observe presence of parked cars.• Observe presence of architectural obstacles.Inspect VisuallyMake a visual check of the site for signs of buried cables such as:• recent trenching• buried cable markers• overhead lines that run down the pole and underground• gas meters• valve sights• drains or manhole coversAcquire Utility MapsVarious companies produce technical maps of existing utilities. While some maps may be very generic, they are an important tool for gathering and interpreting data at the survey site. The maps provide general schematics of the type and position of the utilities managed or constructed by those companies. Request maps by contacting the utility’s cartographic or planning office. Specify the street names and areas of interest. Request maps well in advance of the actual survey. Types of utilities to consider are:• public street lighting• low, medium and high voltage electric cables• water supply• gas• telephone cables• sewers

Operation - 36 2450GR Operator’s ManualSetupCMWSetupPosition 2450GR at jobsite and release rubber keeper to lower antenna to ground. Launch Acquisition SoftwareThe 2450GR software allows scan data to be acquired, saved, and viewed directly in the field. 1. Set the control unit power switch to ON.2. Turn on the tablet PC. (See manufacturer’s instructions for more information.)3. Click the 2450GR icon to launch the software. 4. Monitor progress of software self-tests. If one or more self tests fail: • Check that the control unit power switch is set to the ON position. • Verify that the 2450GR battery is fully charged. • Verify that the tablet PC battery is fully charged. (See manufacturer’s instructions for more information.)• Check all cable connections. Calibrate SystemIMPORTANT: For an accurate survey, calibrate the system at the start of a scan and any time ground conditions change, for example, when moving from grass to concrete, or from concrete to asphalt.To calibrate, open the Radar Setup Window is open: 1. Press START CALIBRATION.2. Push the cart a short distance, 10-15 ft (3-5 m). The unit will calibrate and automatically save the processing parameters and open the Acquisition Selection Window. 3. Enter a job name in the text window and press NEW ACQUISITION.To skip calibration, press SKIP CALIBRATION. Note: If you skip calibration, you will only be able to view pre-existing acquisition maps. IMPORTANT: Once a new survey is named a data file is created and saved in the C:\2450GR\mission directory. All files containing acquired data will be stored in this directory.
2450GR Operator’s Manual Operation - 37ScanCMWScanAcquire Scan Data Ensure that the New Acquisition Window is open. 1. Press START SCAN and push or pull the cart to acquire survey data.2. A radar map will appear on the computer display. Select Shallow, Deep, or Dual to set frequency viewing preference. 3. Watch radar map for signs of buried objects, which appear as hyperbolas on the radar map. Note: The 2450GR can be either pulled or pushed to acquire survey data; however, the entire acquisition must be conducted in the same direction. Follow a grid pattern to scan the survey area. Note: The manufacturer recommends viewing dual frequencies to best detect buried objects.
Operation - 38 2450GR Operator’s ManualScanCMWMark Objects1. When a hyperbola (1) is appears , move the cart in the opposite direction. A vertical white line (2) will display on the radar map. Move the cart until the white line is in the center of the hyperbola. 2. Mark the ground: Use spray paint to mark the location on the ground (shown). A red arrow on the side of the antenna corresponds to the white line on the radar map. 3. Mark the acquisition map: • Using the Up/Down buttons (4), position the red horizontal cursor (3) at the top of the hyperbola. • Press the MARK button (5) to open the Mark Window. (See next page.)

Press the FITTING button (2), then Use the UP and DOWN buttons (3) to adjust the curve to match the hyperbolas. This sets the correct propagation speed to accurately calculate object depth. 2. Select an icon to label the type of pipe you suspect. 3. Press GROUND TRUTH SKETCH (1) to note exact depth of cable or pipe, if known. This information is obtained from outside sources such as technical maps, by opening manhole covers, or by potholing.4. To continue scanning, move 2450GR in original direction. IMPORTANT: The GPR system does not identify what type of pipe or cable is buried. This information can be determined from opening manholes or consulting technical maps.
