DIGITAL CONTROL INCORPORATED DigiTrak Falcon F2 Operator’s Manual 1 Important Safety Instructions General The following warnings relate generally to the operation of DigiTrak locating systems. This is not an exhaustive list. Always operate your DigiTrak locating system in accordance with the manual and be aware of interference that may affect efforts to retrieve accurate data with this locating system. Failure to do so can be hazardous. If you have any questions about the operation of the system, please contact DCI Customer Service for assistance. Warning To prevent potentially dangerous conditions, all operators must read and understand the following safety precautions and warnings and must review this operator’s manual completely before using the DigiTrak Locating System. DigiTrak locating systems cannot be used to locate utilities. Failure to use the front and rear locate points technique described in this manual for locating the transmitter can lead to inaccurate locates. Serious injury and death as well as substantial property damage can result if underground drilling equipment makes contact with an underground utility, including natural gas lines, high-voltage electrical cable, or other utilities. DCI equipment is not explosion-proof and should never be used near flammable or explosive substances. Work slowdowns and cost overruns can occur if drilling operators do not use the drilling or locating equipment correctly to obtain proper performance. Directional drilling operators MUST at all times:  Understand the safe and proper operation of drilling and locating equipment, including proper grounding procedures and techniques for identifying and mitigating interference.  Ensure all underground utilities and all potential sources of interference have been located, exposed, and accurately marked prior to drilling.  Wear protective safety clothing such as dielectric boots, gloves, hard hats, high-visibility vests, and safety glasses.  Locate and track the transmitter in the drill head accurately and correctly during drilling.  Maintain a minimum distance of 20 cm from the front of the receiver to the user’s torso to ensure compliance with RF exposure requirements.  Comply with federal, state, and local governmental regulations (such as OSHA).  Follow all other safety procedures. Remove the batteries from all system components during shipping and prolonged storage. Failure to do so may result in battery leakage, which may lead to risk of explosion, health risks, and/or damage. Store and transport batteries using a suitable protective case that will keep batteries safely isolated from one another. Failure to do so may result in short circuits, which may lead to hazardous conditions including fire. See Appendix A for important restrictions on shipping lithium ion batteries. Use of this equipment is restricted to internal use at a construction site.
DIGITAL CONTROL INCORPORATED 2 DigiTrak Falcon F2 Operator’s Manual Pre-Drilling Testing Before each drilling run, test your DigiTrak locating system with the transmitter inside the drill head to confirm it is operating properly and providing accurate drill head location and heading information. During drilling, the depth will not be accurate unless:  The receiver has been properly calibrated and the calibration has been checked for accuracy so the receiver shows the correct depth.  The transmitter has been located correctly and accurately and the receiver is directly above the transmitter in the drill head underground or at the front locate point.  The receiver is placed on the ground or held at the correct height-above-ground distance, which has been set correctly. Always test calibration after you have stopped drilling for any length of time. Interference The Falcon Frequency Optimizer recommends frequency bands based on measured active interference at a given point in time and space. Interference can change, and performance may vary as a result. If performance drops while drilling, consider switching to the other selected band or using Max mode. Potential Interference Received Interference can cause inaccuracies in the measurement of depth and loss of the transmitter’s pitch, roll, or heading. Always perform a background noise check using your receiver (locator), as well as a visual inspection for possible sources of interference, prior to drilling. A background noise check will not identify all sources of interference, as it can only pick up sources of active interference, not passive interference. Interference, as well as a partial list of sources of interference, are discussed in the section Interference on page 34. Never rely on data that does not display quickly and/or remain stable. Potential Interference Generated Because this equipment may generate, use, and radiate radio frequency energy, there is no guarantee that interference will not occur at a particular location. If this equipment does interfere with radio or television reception, which can be determined by powering the equipment off and on, try to correct the interference using one or more of the following measures:  Reorient or relocate the receiving antenna.  Increase the separation between the receiver and affected equipment.  Consult the dealer, DCI, or an experienced radio/TV technician for help.  Connect the equipment to an outlet on a different circuit.
DIGITAL CONTROL INCORPORATED DigiTrak Falcon F2 Operator’s Manual 3 Battery Pack Storage If you plan to store the battery packs for any period of time, please follow these guidelines.  Do not store the battery pack at temperatures greater than 45° C.  Do not store the battery pack in a fully discharged state.  Do not store the battery pack in the battery charger.  Do not store multiple batteries together where their terminals or other loose conductive materials may contact one another and cause a short circuit. If a lithium-ion battery pack will be stored for an extended period of time, pre-charge the battery to a charge level of 30% to 50% (two or three LEDs illuminated on the meter). Do not store the battery pack for more than one year unless it is periodically recharged to the 30% to 50% level. Equipment Maintenance Turn off all equipment when not in use. Store the equipment in cases, away from extremes of heat, cold, and moisture. Test to confirm proper operation prior to use. Clean the glass screens on the receiver and remote display only with a cleaner specifically formulated to not harm the protective coatings on the glass. If in doubt, use only warm water and a microfiber cloth. Do not use household or commercial window cleaning products that include chemicals such as ammonia, alcohol, or any acidic liquid; these cleaners can contain microscopic abrasive granules that will damage the anti-reflective coating and may cause the display to spot. Clean equipment cases and housings using only a soft moist cloth and mild detergent. Do not steam clean or pressure wash. Inspect the equipment daily and contact DCI if you see any damage or problems. Do not disassemble or attempt to repair the equipment. Do not store or ship this equipment with batteries inside. Always remove the batteries from the equipment before shipping or periods of non-use. The battery charger provided with your DigiTrak locating system is designed with adequate safeguards to protect you from shock and other hazards when used as specified within this document. If you use the battery charger in a manner not specified by this document, the protection provided may be impaired. Do not attempt to disassemble the battery charger, it contains no user-serviceable parts. The battery charger shall not be installed into caravans, recreational vehicles, or similar vehicles.
DIGITAL CONTROL INCORPORATED 4 DigiTrak Falcon F2 Operator’s Manual General Transmitter Care Instructions Periodically clean the spring and threads inside the battery compartment as well as the spring and threads of the battery end cap to ensure a proper power connection with the batteries. Use an emery cloth or wire brush to remove any oxidation that has built up. Be careful not to damage the battery cap O-ring; remove it while cleaning if necessary. After cleaning, use a conductive lubricant on the battery cap threads to keep it from binding in the battery compartment. Note For better battery performance, all DCI battery-powered transmitters ship with both a special battery contact spring and a nickel-based anti-seize lubricant on the battery end cap to aid in electrical contact. Before use, inspect the battery cap O-ring for damage that may allow water to enter the battery compartment. Replace the O-ring if the one installed becomes damaged. Do not use chemicals to clean the transmitter. Placing tape around the fiberglass tube of the transmitter, if space allows, will keep the fiberglass protected from most corrosive and abrasive environmental wear. Falcon transmitters have a threaded hole (1/4”-20 thread) in the battery cap to allow the use of an insertion/extraction tool for installing and removing the transmitters in end-load housings. Ensure that this hole remains clear of debris. Send in the Product Registration Card or register online at access.DigiTrak.com for the 90-day Limited Warranty.
DIGITAL CONTROL INCORPORATED DigiTrak Falcon F2 Operator’s Manual 5 Getting Started Introduction Typical DigiTrak Falcon Locating System Congratulations on your purchase of a DigiTrak Falcon™ F2 walkover locating system, the most advanced method of active interference detection and avoidance available in the HDD industry today. Historically, locating systems have transmitted the underground signal on a single frequency. DCI pioneered this much-copied approach in the early days of the HDD industry. The inherent challenge has always been that because interference varies from jobsite to jobsite, a single frequency transmitter that performs well on one jobsite might not perform well on the next. This limitation creates variability in performance and compromises the success of the bore in areas with high interference. The Falcon Frequency Optimizer scans the bore site for interference on multiple frequencies in a matter of seconds. When optimization is complete, it assembles the frequencies with the lowest noise (least amount of active interference) into nine different frequency bands shown on a simple graph. Choose the band best for the job at hand—typically the band with the lowest noise level—pair the transmitter to the receiver with a simple infrared command, and in seconds, the Falcon F2 locating system is ready to drill. Assign a second optimized band as an alternate. At your next bore, re-scan and choose the best bands for the new job site. Now you can say goodbye to purchasing and keeping track of multiple transmitters—simply optimize your Falcon F2 dual wideband transmitter and drill with the lowest-noise frequencies every time.

If not, verify proper region is set on both devices. Transmitter 1. Compare the regional designation number in the globe on the transmitter with the number in the globe on the receiver startup screen. If they don’t match, contact DCI Customer Service. 2. Do not power on the transmitter until after running the Frequency Optimizer (see next section). 3. If you will be using the Frequency Optimizer, transmitter orientation while powering on does not matter. Batteries and Power On/Off Page 57
DIGITAL CONTROL INCORPORATED 8 DigiTrak Falcon F2 Operator’s Manual Jobsite Setup Getting started with Falcon is easy: run the Frequency Optimizer, choose a band, pair the receiver with the transmitter, calibrate, check range, and check for active interference. These tasks are described in detail starting with Receiver Menus on page 13. Using the trigger Page 10 Click the trigger to move between menu options. Hold briefly and release to make a selection. Do nothing in a menu for five seconds to return to the Locate screen. Run Frequency Optimizer 1. With the transmitter off (batteries not installed), take the Falcon receiver to the point along the intended bore that might create the biggest locating challenge, such as being the deepest point of the bore or an area with obvious active interference such as power lines, railway crossings, traffic lights, or transformers. 2. Power on the receiver and select Frequency Optimizer (FO) from the Main menu. Frequency Optimizer Page 14 3. With the FO results active, walk the entire intended bore path with the receiver and flag areas of high background noise (active interference). The higher a frequency band's bar is on the graph, the greater the interference. Note which band remains consistently low, since the band with the lowest level of interference will likely be the one you want to use. -90 to -72 dB Low interference levels -72 to -54 dB Moderate interference -54 to -18 dB Interference will become an issue as depth increases Repeat the above steps as necessary to help determine the lowest-noise frequency band to use. Choose a Band 1. Insert batteries in the transmitter, positive end first. 2. On the receiver, click to move the selector on the bottom of the Frequency Optimizer graph to the band you want to use and hold briefly to select. 3. Assign as the Up or Down band. 4. Optional: select and assign a second frequency band. 5. Select Pair . 6. Align the receiver and transmitter IR windows within two inches of each other and select the check mark to pair. A successful pairing is indicated by a beep and a check mark.
DIGITAL CONTROL INCORPORATED DigiTrak Falcon F2 Operator’s Manual 9 Are high frequency bands better than low frequency bands? Different bands are better for different kinds of interference. Lower frequency bands like 7 and 11 are typically better around rebar, passive interference, and salt water. Higher frequency bands can perform better in deeper bores, plus have longer Target Steering capability. Calibrate After a successful pairing the receiver continues to the Calibration screen as a reminder that with a new optimized frequency band, calibration is required. Perform a 1-point (1PT) calibration in a low-noise area with the transmitter in a housing. Always calibrate after assigning a new frequency band. Calibration Page 20 Above Ground Range Check Perform an Above Ground Range check on the new optimized frequency band before drilling. The AGR screen displays automatically after calibration. Perform an AGR test on both frequency bands Page 22 Calibrate each frequency band separately. Performing an AGR test on both frequency bands at every jobsite is just good practice. If the above-ground AGR distance at 15 m is not accurate, conduct a 15M calibration (which also uses only one point) to improve the accuracy of the above-ground distance measurement. A 15 m calibration is not necessary for drilling. Calibration Page 23 Interference Check Check for active interference on both frequency bands to verify it does not interfere with the transmitter's signal. Interference Page 34

DIGITAL CONTROL INCORPORATED 14 DigiTrak Falcon F2 Operator’s Manual Frequency Optimizer The Frequency Optimizer (FO) feature finds the lowest-noise (optimal) group of frequencies available in each of nine bands. When the results display in graph form showing the levels in each band, choose the one or two bands you want to use, pair, and you're ready to calibrate and start drilling. You can switch the transmitter between the two optimized bands at any time, either pre-bore or mid-bore. Start in the optimized band that works best for the normal-interference portion of the bore and switch to the other band that works better for the portion that has higher interference. Or use one optimized band for the whole bore, or start drilling in one optimized band and switch only if you need to. The choice is yours. Do I have to optimize every time I power the receiver on? Page 57 No, the receiver remembers both optimized bands until you pair it to a new band. Power the transmitter on horizontally to use the last active band. If my optimized band worked great at my last jobsite, can I keep using it at my next one? Because sources of interference differ at every jobsite, DCI recommends optimizing at every job site to obtain the best selection of frequencies for the current conditions. Some of my bands are missing on the optimizer. Is my Falcon F2 broken? No. A maximum of nine bands are available, but some country regulations limit the number of frequencies and bands available. To optimize and select a frequency band: 1. Ensure all transmitters are powered off or are more than 30 m away from the receiver. 2. From the Main menu, select Frequency Optimizer . The Falcon F2 receiver scans and measures the background noise (active interference) in multiple frequencies. The display will cycle through each band for about 15 seconds as shown below while it is scanning. Frequency Optimization Graph while Scanning Pair Current Up band Current Down band
DIGITAL CONTROL INCORPORATED DigiTrak Falcon F2 Operator’s Manual 15 When frequency optimization is complete, the receiver shows the background noise currently present in each of the nine frequency bands using an optimized selection of the lowest-noise frequencies within each band. The shorter the bar on the graph, the less interference present in that band. Frequency Optimizer Results 3. To measure noise readings from the entire intended bore, simply walk the bore with the frequency optimization results displayed. As the receiver continues sampling background noise, it marks the maximum noise reading of each band at the top of each bar. Before choosing a frequency band, consider not only which bands remained consistently low, but also which did not experience significant maximum noise readings. Optimize as often as you want. You can't wear it out. If you discover a significant source of active interference while walking the intended bore, select a frequency band that was performing well prior to this point, then select and assign the second band for the high-interference area. Or optimize again before assigning the second band. Optimize as often as you want before assigning a band. 4. Click to move the selector to the band you want to use and hold briefly to select. Typically this will be a band that remained at a low interference level and did not experience high maximum noise readings while walking the bore path. Band Number 7 11 16 20 25 29 34 38 43 Range in kHz 4.5–9.0 9.0–13.5 13.5–18 18–22.5 22.5–27 27–31.5 31.5–36 36–40.5 40.5–45 5.

Up Down Cancel Exit Band selector Maximum noise reading Median kHz of each band Current optimized noise readings
DIGITAL CONTROL INCORPORATED 16 DigiTrak Falcon F2 Operator’s Manual Note If the band number you want to use is already displayed at the right edge of the screen, reassign it anyway, as the newly optimized group of frequencies in that band will be different than those in the existing group. 6. Click to select a second band, then assign as the other band (Up or Down); changing both bands is optional. With two new bands, the receiver and transmitter will begin using the Down band first. 7. Select Pair . If you assigned two new bands, both will pair at the same time. 8. The receiver displays the transmitter pairing screen. Insert batteries in the transmitter, install the battery cap, and wait 15 seconds for the transmitter to fully power on. Transmitter Page 56 9. Hold the infrared (IR) port of the transmitter within 5 cm of and facing the IR window on the front of the receiver. 10. Select the check mark to pair the transmitter frequency band to the receiver. Transmitter Infrared (IR) Pairing Screen Hold the transmitter in place up to ten seconds for pairing. A circling icon indicates the receiver and transmitter are not yet connected; check alignment and proximity of the IR ports. Moving the transmitter after pairing begins may cause an error code to display on the screen; if this happens, simply restart the pairing process. Can I exit the pairing screen and go back to the optimizer results without running it again? Yes. Select Return to go back to the frequency optimization results, erase the maximum readings, and continue observing the noise readings of the last optimized frequency bands. Select X to return to the Locate screen. Pair Return to optimizer results Transmitter IR port
DIGITAL CONTROL INCORPORATED DigiTrak Falcon F2 Operator’s Manual 17 11. When the pairing is successful, the receiver/transmitter icon briefly changes to a check mark and the receiver beeps. Both the receiver and transmitter are now using the new optimized band you selected. If you assigned two new bands, the system is set to use the Down band first.  If the pairing is unsuccessful, the receiver/transmitter icon will briefly change to an X and then the Transmitter Pairing screen will reappear. Try pairing a second time. If still unsuccessful, remove and reinstall the transmitter batteries and battery cap, realign the two IR windows, and try again. If still unsuccessful, Return to the FO results and go back to step 4.  If the pairing doesn't complete, no new optimized frequency is stored in the receiver. Upon exiting the Frequency Optimizer screen, the receiver remains paired to the transmitter at the last optimized band used.  The second band can be paired to a completely different optimization. After pairing the first band, simply run the Optimizer at a new location, select a band, and assign as the other (Up or Down) band. 12. The receiver proceeds to the calibration screen as a reminder that with the selection of a new frequency band, the transmitter and receiver need to be recalibrated. After 10 seconds, the calibration failure notice displays. Click to acknowledge the notice, install the transmitter in the drill head, and select Calibration from the Main menu. Prior to calibration, "Calibration required" is indicated on the Locate screen by an exclamation mark in the roll indicator in place of the roll value. To change between bands mid-bore, both bands must be separately selected and calibrated prior to drilling. Calibration Page 20 Main Menu Page 13 The transmitter is now set to use the new optimized frequency band you just selected (or the Down band, if you assigned both) and is paired to the receiver. Before or during drilling, switch between bands any time if interference is compromising the current band. Changing Frequency Bands Page 61 The orientation of the transmitter when it powers on—up, down, or horizontal—determines the initial frequency band it will use. Installing Batteries / Power On Page 57 Power Off Select Power Off from the Main menu to turn the receiver off. The receiver automatically shuts down after 15 minutes of inactivity or after 30 minutes when in Target Steering mode. Is it okay to power off by just pulling the battery out? Yes, Falcon F2 can handle it.
DIGITAL CONTROL INCORPORATED 18 DigiTrak Falcon F2 Operator’s Manual Height-Above-Ground (HAG) Use Height-Above-Ground (HAG) to set a height measurement on the receiver so you don’t have to set it on the ground for a depth reading. Raising the receiver above the ground also provides separation from underground interference that might otherwise reduce the transmitter’s range or cause variable readings. To prevent incorrect readings, Falcon F2 always powers up with the HAG function off (disabled). HAG also automatically shuts off during calibration and when you change depth units, and is ignored during an AGR test and Target Steering. Until you enable HAG, the receiver must be placed on the ground for accurate depth readings. Calibration Page 20 AGR Test Page 22 Depth Units Page 24 Target Steering Page 51 I use HAG all the time; can I set it to turn on automatically? No. In the name of safety, HAG must be turned on manually for each use. However, the feature does remember the last height value used. To determine your desired HAG distance, hold the receiver comfortably at your side, maintaining 20 cm of separation from the front of the receiver to your torso as specified in the Safety section on page 1. Measure the distance from the bottom of the receiver to the ground. HAG may be set from 30 to 90 cm. The HAG menu has three options: Turn on, Turn off, and Set. Click the trigger to reach the desired option, then hold briefly to select. Turn HAG On The first screen shows either the default HAG value of 30 cm or the value that was most recently set. To set a different value for HAG or to turn it off, click the trigger to advance to the next screen and skip the rest of this section. Otherwise, continue below. This Turn HAG On screen shows the Falcon F2 receiver 30 cm above the ground. To turn on HAG using the height value displayed, hold the trigger briefly. The receiver beeps and confirms with a checkmark  to indicate HAG is now on, then returns to the Locate screen. Depth readings (holding the trigger) must now be taken with the receiver held at this height. Turn HAG On

DIGITAL CONTROL INCORPORATED 20 DigiTrak Falcon F2 Operator’s Manual Calibration and AGR Use the Calibration menu to calibrate the receiver to a transmitter and to verify the Above Ground Range (AGR). Calibration is required prior to first-time use and before using a different transmitter, receiver, drill head, or transmitter band. Calibrate each optimized band separately If you select an optimized band that has not been calibrated yet, appears in the roll indicator. Calibrate and verify Above Ground Range separately for each optimized frequency band prior to each job. Do not calibrate if:  You are within 3 m of metal structures, such as steel pipe, chain-link fence, metal siding, construction equipment, automobiles, etc.  The receiver is over rebar or underground utilities.  The receiver is in the vicinity of excessive electrical interference, as shown by high background noise readings on the Frequency Optimizer results.  The transmitter is not displaying transmitter data.  The signal strength from the transmitter is less than 300 points (too low) or greater than 950 points (too high). Outside this range, a calibration failure screen will indicate low or high signal strength (see step 6 on page 22). Frequency Optimizer Results Page 15 Installing Batteries / Power On Page 57 The transmitter must be installed in a drill head during calibration. During calibration, HAG is automatically turned off. After calibration, HAG must be turned back on manually. 1. Place the receiver and the transmitter (in a drill head) parallel to each other on level ground, with both devices powered on. 2. With the receiver at the Locate screen, verify that roll and pitch values are being displayed and that a steady signal is being received from the transmitter. Record the transmitter’s signal strength at the 3 m calibration distance so it can be compared to future signal strength values. A change in signal strength can indicate you are currently in an interference environment or there is a problem with your equipment.
DIGITAL CONTROL INCORPORATED DigiTrak Falcon F2 Operator’s Manual 21 3. At the Main menu, select Calibration and then 1PT (1-point) calibration. Receiver Calibration Screen 4. Use a tape measure to ensure the distance from the center of the transmitter to the inside edge of the receiver is 3 m as shown below, then click to begin the calibration. Calibration Prompt If you wait longer than about 15 seconds to click the trigger, the calibration terminates and the Above Ground Range (AGR) screen displays (see next section). 5. The display counts down to zero while the receiver records the calibration point. Do not move the receiver. Trigger click prompt (flashes)
DIGITAL CONTROL INCORPORATED 22 DigiTrak Falcon F2 Operator’s Manual 6. A successful calibration yields a checkmark above the transmitter icon and four beeps. An unsuccessful calibration yields an X above the transmitter icon and two beeps. The symbol indicates low signal strength, and indicates high (excessive) signal strength. Calibration will fail when the signal from the transmitter is below 300 or above 950 points. Why do I keep getting calibration errors? Carefully review the items under "Do not calibrate if" at the beginning of this section. Try calibrating in a different location. Make sure the transmitter is on and paired (data showing on the Locate screen). If you're still having trouble, give us a call, we'll get you going. Above Ground Range (AGR) After successfully completing a 1-point calibration, the receiver displays the Above Ground Range screen, an active measurement between the transmitter and receiver. Use this screen along with a tape measure to verify calibration of the transmitter at different distances. With the transmitter level, the depth readings should be within ±5% of the measured distance. Note To perform an AGR check without re-calibrating the transmitter, follow the 1-point calibration instructions in the previous section up to step 3, but do not click the trigger to perform the calibration . The procedure will time out to the AGR screen after several seconds. Above Ground Range (AGR) Note that because AGR intentionally does not consider pitch when calculating range, it displays a symbol indicating "Warning, pitch is unknown, assume zero". It also ignores any HAG setting. Locate Screen Page 29 Pitch assumed zero Unsuccessful Successful
DIGITAL CONTROL INCORPORATED DigiTrak Falcon F2 Operator’s Manual 23 Use AGR at least daily, and ideally in both frequency bands, to verify proper depth (distance) measurements. After Calibration If necessary, turn Height-Above-Ground (HAG) back on. Height-Above-Ground (HAG) Page 17 15 m Calibration (Optional) This feature is only used for verifying above-ground AGR distance measurements beyond 12.2 m. A 15M (15 meter) calibration does not affect depth readings on the Locate screen. Only a 1PT 3 m calibration is necessary for below-ground depth readings. Above-ground distances beyond 12.2 m may read shorter than normal due to what is known as "surface effects." Varying amounts of conductivity in the surface of the earth make distance readings read shallower than actual, with the amount of error varying with ground conditions. If you have completed a 1PT 3 m calibration and AGR distances beyond 12.2 m are reading short, perform a 15M calibration (which also uses only one point) to refine the AGR measurement. Note If the AGR reading at 15 m is less than 13.7 m or greater than 15 m, this calibration will fail. The 15M calibration does not properly correct for active or passive interference. 1. Follow the same procedure as described for 1PT calibration in Calibration and AGR on page 20, but at the calibration screen mentioned in step 3, select 15M instead of 1PT. 2. Follow the remainder of the procedure, including conducting an AGR test. Do I have to do a 15M calibration before I can drill? No. A 15M calibration only helps with above-ground measurements. Use it if the AGR test reveals shorter than actual distance readings beyond 12.2 m. After the 15M calibration, use the subsequent AGR test to verify the adjusted distance readings.

Due to the nature of the extreme depth and/or high-interference environment where use of Max mode will typically occur, the risk of obtaining unreliable data is increased. Never rely on data that does not display quickly and remain stable. Max mode is never a substitute for prudent operator judgment. The purpose of Max mode noise filtering is to stabilize erratic roll/pitch data, depths, and locates when drilling at the very limit of the ability of the transmitter due to extreme depth or interference, which will vary by jobsite.

Receiver Depth Screen with HAG Enabled (not at FLP, RLP, or LL) Interference Interference can compromise a transmitter's signal even when drilling with an optimized frequency band. It is important to the success of your bore that, after pairing your transmitter at a newly optimized frequency, you check how the transmitter's signal will perform along the intended bore path. Warning To best overcome interference, find and deal with it above ground, before you start drilling. What is Interference? Interference can reduce the transmitter’s range or cause variable readings and possibly result in job slowdowns. Interference is classified as either active or passive. Active interference, also known as electrical interference or background noise, can have varying effects on locating equipment. Most electrical devices emit signals that can inhibit the ability to locate the transmitter accurately or get good roll/pitch readings. Examples of active interference include traffic signal loops, buried dog fences, cathodic protection, radio communications, microwave towers, cable TV, fiber-trace lines, utility data transmissions, security systems, power lines, and phone lines. Interference at the remote display may also occur from other sources operating nearby on the same frequency. The following section describes how to use the receiver to test for the presence of background noise. Slanted line indicates receiver is not at FLP, RLP, or LL
DIGITAL CONTROL INCORPORATED DigiTrak Falcon F2 Operator’s Manual 35 Passive interference can reduce or increase the amount of signal received from the transmitter, which results in incorrect depth readings, a completely blocked signal, or locates in the wrong position. Examples of passive interference include metal objects such as pipes, rebar, trench plate, chain-link fence, and vehicles. Two other examples are saltwater/salt domes and conductive earth, such as iron ore. The receiver cannot test for the presence of passive interference. Conducting a thorough site investigation prior to drilling is the best method of identifying passive interference sources. To familiarize yourself with the interference potential along your intended bore path, check for background noise as discussed in the following section. Warning A receiver cannot detect sources of passive interference; this can only be accomplished with a visual inspection of the jobsite. A background noise check can only find active interference. I thought the Frequency Optimizer did all this for me? The Frequency Optimizer finds the lowest-noise frequencies to use in each band. You choose which bands to use and pair the transmitter. As best practice, now test those bands above ground to ensure the receiver receives data for the intended portion of the bore. A good background noise check is vital to a job free of interference surprises. Checking for Interference To check for active interference, walk the intended bore path with the receiver in the frequency band you intend to drill with. Do this with the transmitter off, while taking note of the signal strength on the Locate screen. With no transmitter on, this “signal strength” is in fact background noise (active interference). In the following figure, the red flag area denotes an increase in background noise detected while walking the intended bore path with the receiver. One-Person Background Signal Strength Check (Transmitter Off) Now return to the area of highest interference (between the red flags above), turn on the transmitter, and place it the same distance to the side of the receiver as the intended bore depth. Verify that the roll/pitch data is consistent and correct in the flagged area. The transmitter’s signal strength should generally be a minimum of 150 points greater than the LLIntended bore path Background noise signal Red flag area
DIGITAL CONTROL INCORPORATED 36 DigiTrak Falcon F2 Operator’s Manual background interference reading. For example, if this area of greatest interference produced a signal strength reading of 175, the reading with the transmitter on at this location, and at a distance from the receiver equal to the maximum intended bore depth, should be a minimum of 325 (175 + 150). Note that the transmitter’s signal strength will be slightly higher in this test than while drilling because it is currently not encased in the drill head, which will diminish the signal strength slightly. Areas where the background noise level is too high may make it difficult to obtain roll and pitch data and accurate locates and depth. If the receiver signal strengths were not strong, conduct a roll/pitch check as described in the following section. Roll/Pitch Check With a strong signal, this test isn't always necessary If the receiver signal strengths are well above the minimum, a roll/pitch test isn't entirely required. But as best practice, or if sections of the bore produce significantly decreased signal strength, this is an important check prior to drilling. At the exit end of the bore path, turn the receiver to face the launch point and install batteries in the paired transmitter to turn it on. Have a coworker hold the transmitter and stand beside you. Walk together in parallel back toward the launch point, keeping the receiver over the bore path and the transmitter at a distance of 1 to 1.5 times the current intended bore depth; where the bore is deeper, your coworker will be farther away. Periodically stop and change the transmitter’s roll and pitch orientation so you can verify the speed and accuracy of these readings on the receiver. It is good practice to also have a coworker monitor the readings at the remote display at the same time. Note any locations where the receiver or remote display information becomes erratic or disappears. If roll/pitch data or signal strength become unstable, hold the trigger to see if Max Mode can stabilize the data.

Set the receiver and remote display to use a different telemetry channel. An optional extended-range telemetry antenna may also help overcome some forms of interference. Never rely on the receiver as the sole means of communication between the receiver operator and drill operator. In cases where data is not available on the remote display, both operators must be able to communicate with each other. Locate Points (FLP & RLP) and Locate Line (LL) The Falcon F2 receiver locates the transmitter by detecting three specific places in the transmitter’s magnetic field: the front locate point (FLP) ahead of the transmitter, the rear locate point (RLP) behind the transmitter, and the locate line above the transmitter itself. The locate points are indistinguishable from one another by the receiver as they represent similar points in the transmitter’s field in front of and behind the transmitter (see Appendix C on page 67 for more information about the transmitter’s magnetic field). The locate line (LL) extends 90° to the left and right of the transmitter (perpendicular) when the transmitter is at 0% pitch. It represents the location of the transmitter between the FLP and RLP. If you think of the transmitter being the body of an airplane, its wings are the locate line. Locate line does not equal the location of the transmitter Being over the locate line does not mean you are over the transmitter, which may be left or right anywhere along the locate line. You must find the front and rear locate points to find the transmitter, as is detailed on the next couple pages.
DIGITAL CONTROL INCORPORATED 38 DigiTrak Falcon F2 Operator’s Manual The most accurate tracking requires the use of all three locations to determine the position, heading, and depth of the transmitter. A line passing through the FLP and RLP reveals the heading and left/right position of the transmitter. The LL determines the position of the transmitter when the receiver is properly aligned between the FLP and RLP (on the line). Geometry of FLP, RLP, and LL from Top (Bird’s-Eye) and Side Views Note how the RLP and FLP are equal distances from the LL when the transmitter is level. The line marked LL in the bird’s-eye view image suggests the receiver will display a locate line any time it is positioned on this plane. To prevent inaccurate locates and potentially dangerous conditions, it is imperative to first find the front and rear locate points. Do not rely on the peak signal along the locate line. Note Whenever the transmitter is pitched, the position of the locate line will be somewhat slightly ahead of or behind the transmitter’s actual position. This slight fore/aft offset will increase with depth (see Appendix C). In these cases, the depth displayed on the receiver is referred to as the projected depth.

DIGITAL CONTROL INCORPORATED DigiTrak Falcon F2 Operator’s Manual 39 Effects of Depth, Pitch, and Topography on Distance Between FLP and RLP The deeper the transmitter is, the farther apart the FLP and RLP will be. The distance between the FLP and RLP with respect to the location of the LL is also a function of the transmitter pitch and the topography. When the transmitter pitch is negative, the FLP will be farther from the LL than the RLP. When the pitch is positive, the RLP will be further from the LL than the FLP. If the ground surface or topography slopes significantly, the locations of the FLP and RLP will also be affected with respect to the LL even if the transmitter itself is level. Effect of Pitch on Distance Between FLP, RLP, and LL For a detailed explanation of how to track the transmitter when it is steep and deep, read the information provided in Appendix C: Projected Depth Versus Actual Depth and the Fore/Aft Offset on page 67.

DIGITAL CONTROL INCORPORATED 40 DigiTrak Falcon F2 Operator’s Manual Marking Locate Points The locate points (FLP and RLP) and the locate line (LL) must be found and accurately marked during the locating procedure. To mark a locate point, stand with the receiver level at the locate point. Look down the vertical axis that runs through the center of the display to project a plumb line to the ground. Mark where this plumb line hits the ground. Plumb Line for Marking Locate Points Locating the Transmitter Falcon F2 can locate the transmitter and its heading while it moves, whether in front of the transmitter, behind it, or beside it. It can locate the transmitter while facing toward or away from the drill rig. The standard method described in this section guides the receiver to the transmitter while standing in front of it, facing the drill rig. This is the recommended method for locating. As you continue to drill or as the bore path curves, you may be facing the last marked locate point rather than the drill rig.

Finding the Front Locate Point (FLP) The locating procedure described here assumes that (a) you are facing the drill, (b) the transmitter is below ground and between you and the drill, and (c) the FLP is in front of you. 1. Start with the receiver on and in Locate mode. 2. Stand in front of the drill head at a distance of approximately the drill head depth. 3. Observe the position of the locating ball ( ) relative to the receiver box on the display. The figures below show the FLP ahead of and to the left of the receiver; as the drill head gets deeper, the FLP will be found farther in front of the transmitter.

When the ball is centered in the box (Ball-in-the-Box™), hold the trigger for at least one second so the receiver can “lock” onto the reference signal. The “R” symbol will appear at the top of the Depth screen. The locate line (LL) will not display later without this reference. Receiver Depth Screen at FLP with HAG On Actual Position of Receiver and Transmitter Warning When setting a reference signal, do not hold the trigger unless you are Ball-in-the-Box™ at the FLP. If you are ahead of the FLP, you could set an incorrect reference that causes a ghost locate line. This typically happens when the head is shallower than 1 m. In this case, you must reference again at the FLP. If you hold the trigger for longer than five seconds, the receiver will enter Max mode, which performs differently than a normal depth reading. Max Mode Page 31 The depth value given at the FLP is the predicted depth, which is the depth the transmitter is calculated to be at when it reaches the location beneath the receiver. If the pitch or heading of the transmitter changes before it reaches the location under the receiver, the predicted depth reading will no longer be accurate. Quick receiver self-check To verify that the signal is balanced through the receiver’s antenna, carefully rotate the receiver 360° about the center of the display while keeping the receiver level. The locating ball should stay centered in the box. If it does not, do not continue to use the receiver and contact DCI Customer Service. 6.

Keep the locating ball on the vertical crosshair and observe that the signal strength is increasing. Receiver Locate Screen, Moving Toward LL, FLP Behind If the signal strength decreases, you may actually have just located the RLP. Position yourself farther away from and facing the drill to locate the FLP. 8. When the locating ball reaches the bottom of the screen, the locate line appears and the ball turns solid black to indicate your focus should now be on the LL. If the locate line does not appear and the ball flips to the top of the screen, hold the trigger while moving the receiver in a forward/backward direction over where the ball flips. This action should re-reference the receiver to the transmitter’s signal and bring up the locate line. If it does not, return to the FLP to re-reference (see step 1).

Use off-track locating when it is not possible to walk above the transmitter due to a surface obstruction or interference. Using the locate line’s perpendicular relationship to the transmitter, it is possible to track the transmitter’s heading and also determine if it is maintaining its intended depth. The off-track locating method is only effective when the pitch of the transmitter is 0% (0°) and traveling under flat ground. To explain how the off-track locating method works, consider the example of an obstruction that is on the intended bore path, as shown in the figure below. The transmitter is about to go under the obstruction. 1. Stop drilling and find the locate line (LL) of the transmitter by putting the line in the box. 2. While holding the receiver in the same orientation, step to the side until you reach a predetermined distance (P1). Move the receiver forward and backward until the ball jumps between the top and bottom of the screen, then mark this location.

DIGITAL CONTROL INCORPORATED 50 DigiTrak Falcon F2 Operator’s Manual Preparing for Off-Track Locating 3. While still holding the receiver in the same orientation, step to the side another predetermined distance (P2) farther away. Move the receiver forward and backward until the ball jumps between the top and bottom of the screen, then mark this location. 4. While still holding the receiver in the same orientation, step to the side of the drill head another predetermined distance (P3) farther away. Move the receiver forward and backward until the ball jumps between the top and bottom of the screen, then mark this location. 5. Connect points P1, P2, and P3 with a line. This is the locate line. Because the LL runs perpendicular (at a 90° angle) to the transmitter when the transmitter is level, you can determine the heading of the drill head. By comparing the signal strength at the predetermined distances of P1, P2, and P3, as the drill head progresses, you can verify it is moving away from or maintaining the intended bore path. It is important to monitor the pitch of the transmitter to ensure the drill head is maintaining the desired depth. 6. As drilling continues, steer the drill head to maintain a constant signal strength at each of the points P1, P2, and P3. If the signal strength decreases, the drill head is moving away; if it increases, the drill head is moving toward the side position. Differences in pitch and topology elevations will also affect the signal strength and LL position as the drill head progresses.

DIGITAL CONTROL INCORPORATED DigiTrak Falcon F2 Operator’s Manual 51 Target Steering The Target Steering locating method allows the Falcon F2 receiver to be placed ahead of the drill head and used as a steering target. In general, Target Steering should be used to maintain a bore path, not to bring a significantly off-course bore back on track. If needed, use front and rear locate methods to get back on course. Locate Points (FLP & RLP) and Locate Line (LL) Page 37 Note After learning the concepts of Target Steering, practice its use before using on a jobsite where time and money are at a premium. A Look-Ahead Locating animation is also available at www.youtube.com/dcikent. If you need further assistance, please contact DCI Customer Service. The Falcon Compact Display supports Remote Steering, which provides left/right steering guidance but not depth. For Target Steering at the drill, DCI recommends the Aurora touchscreen remote display. Using the receiver for Target Steering requires a stable signal from the transmitter. Target Steering will not work properly with passive interference in the vicinity of the bore. Interference Page 34 Feasible Target Depth The maximum distance the receiver can be placed ahead of the drill head for Target Steering is 10.7 m. Beyond this distance, depth information becomes less accurate. Within this range, starting with the drill head approximately level, the following parameters apply to depth data:  The maximum depth change is approximately 1.2 m.  The maximum pitch change is approximately 14%. For the most conservative Target Steering operation, assume the ideal drill path is a circular arc with a radius that accommodates the bend radius of most drill strings and products being installed. As shown in the diagram below, the feasible steering area is limited to the shaded region bounded by the two circular arcs.

DIGITAL CONTROL INCORPORATED 52 DigiTrak Falcon F2 Operator’s Manual The Target Steering procedure requires correct placement of the receiver at less than 10.7 m in front of the transmitter, on the bore path, with its back end (where the battery pack is inserted) facing the drill. When used to provide only the right/left Remote Steering signals accepted by the Falcon and Aurora remote displays, the distance between receiver and transmitter is limited only by the range of the transmitter. Use the three screens in the Target Steering menu on the receiver to turn Target Steering On, turn Target Steering off, or set the target depth, as described in the following sections. Turning Target Steering On Use the first screen in the Target Steering menu to turn remote steering on at the target depth displayed, which is either the default value of 0.50 m or the most recently-set value. The target depth is the depth at which you want the transmitter when it passes under the receiver. To change the target depth, click twice and skip to Setting the Target Depth on page 53.

If you think you're getting a great online deal on a substitute Falcon transmitter, you are being scammed for a device that does not exist. Just saying. If you purchase a "remanufactured" transmitter, do so with the following considerations: (1) You must be willing to bet an entire day's work on thermally abused transmitter components that would likely fail a bench test. (2) You must have a good reason ready for the boss for why DCI customer service will not provide assistance when your transmitter that is registered to someone else fails on your job mid-bore. And, (3) you must be willing to risk bodily harm, property damage, and the potential financial devastation of your company just to save a few bucks on an inferior, potentially dangerous, recycled device that is a lawsuit waiting to happen.

Starting the Frequency Optimizer will not change the transmitter's optimized frequency bands until the receiver and transmitter are paired. Once paired, the transmitter automatically begins using the new optimized frequency band. With two new bands, the receiver and transmitter will begin using the Down band first. Transmitter Battery Strength The battery strength icon at the bottom of the receiver’s Depth screen indicates the battery life remaining for alkaline batteries. It also appears at the bottom left of the Locate screen for the first five minutes the transmitter is powered on. Until the transmitter is installed in a housing and therefore drawing normal current, this strength reading will not be accurate. Warning Because the battery status for a SuperCell battery will appear full until just before it is fully depleted, you must track its hours of use. Transmitter Current Draw Warning Transmitter over-current—drawing too much current from the batteries, which shortens battery life—may occur due to weak or used batteries or use of an incompatible drill housing. Excessive current is indicated by a lightning bolt over the transmitter battery strength icon on the Locate screen. 1.5 V 1.5 VSuperCell 3.6 V1.5 V 1.5 VSuperCell 3.6 V
DIGITAL CONTROL INCORPORATED DigiTrak Falcon F2 Operator’s Manual 59 The Falcon F2 transmitter only performs this current draw test for five minutes after powering on. The transmitter must be installed in the drill head for this test to be valid. Different drill heads and slot arrangements will affect current draw and battery life. Sleep Mode All battery-powered DigiTrak transmitters go into sleep mode and stop transmitting to conserve battery power if they are stationary for longer than 15 minutes. To awaken the transmitter, rotate the drill string a half turn; a transmitter will not awaken if it lands on the same roll position at which it went to sleep. A small amount of charge will continue to drain from the batteries while the transmitter is in sleep mode so it can monitor roll position. To conserve battery life, do not leave batteries in the transmitter when they can be easily removed. Always remove batteries when the transmitter is not being used to turn it off. Note A transmitter will continue sending data for up to 10 seconds after the batteries are removed. If you have removed the batteries and intend to restart the transmitter in another frequency, wait until data has stopped displaying on the receiver before reinstalling the batteries. Transmitter Drill Head Requirements For maximum transmitter range and battery life, the slots in the drill head must meet minimum length and width requirements and be correctly positioned. DCI transmitters work best with three slots that are equally spaced around the circumference of the drill head for optimal signal emission and maximum battery life. The slots must be at least 1.6 mm wide. For accuracy, slot measurements must be taken on the inside of the drill head. A Minimum B Maximum C Falcon F2 Wideband 22.9 cm* 2.5 cm* 38.1 cm * Ideal measurement. The DCI standard slot length of 21.6 cm and B distance of 5.1 cm remains acceptable. A transmitter must fit snugly in its drill head. It may be necessary to wrap the transmitter with tape or O-rings and/or to use a drill head adapter for larger drill heads. Contact DCI Customer Service for more information. The index slot in the front end cap of the transmitter should fit onto the anti-roll pin (key) in the drill head for proper alignment.

Temperature Status and Overheat Indicator All DigiTrak transmitters are equipped with an internal digital thermometer. The temperature displays on the bottom right of the receiver and remote display screens next to the transmitter temperature symbol . Normal drilling temperatures range from 16 to 40° C. Suspend drilling when temperatures exceed 36° C to permit cooling. Note Because the digital thermometer is inside the transmitter, temperature increases due to external drilling conditions will take time to transfer to the transmitter. Resolve increases in temperature quickly to avoid irreversible damage. If the temperature reaches 48° C, the thermometer icon will change to show that the transmitter is becoming dangerously hot . The transmitter must be allowed to cool immediately or it will be damaged. To cool the transmitter, stop drilling and retract the drill bit a few feet and/or add more drilling fluid. Transmitter Temperature Warning Tones The Falcon F2 receiver and remote display emit the following audible tones to indicate increases in the transmitter temperature: Icon Temperature Warning Tones Below 16° C None 16–36° C Double-beep sequence (beep-beep) for every 4° C increase in temperature. 40–44° C Two double-beep sequences (beep-beep, beep-beep) for every 4° C increase in temperature.

Cooling is critical to avoid irreversible damage. flashing Above 60° C Three double-beep sequences every 5 seconds on the remote display, and every 20 seconds on the receiver. This warning signifies dangerous drilling conditions; irreversible damage may have already been done to the transmitter. 104° C None: transmitter overheat indicator (temp dot) turns black.
DIGITAL CONTROL INCORPORATED DigiTrak Falcon F2 Operator’s Manual 61 Transmitter Overheat Indicator (Temp Dot) Each transmitter has a temperature overheat indicator (temp dot) on the front end cap. The temp dot has an outer yellow ring with a 3 mm white dot in the center. The white dot will change color if the transmitter is exposed to excessive heat. Transmitter Temp Dot If the temp dot changes to silver or gray, the transmitter has been exposed to heat but not in excess of specifications. If the temp dot is black, the transmitter has been exposed to excessive temperatures (over 104° C) and can no longer be used. The DCI warranty does not cover any transmitter that has been overheated (black dot) or had its temp dot removed. Avoid transmitter overheating by practicing proper drilling techniques. Abrasive soils, clogged jets, inadequate mud flow, and improperly mixed mud all contribute significantly to the over-heating of a transmitter. Changing Frequency Bands Use these procedures to switch between the two optimized frequency bands, such as when performing an AGR test in both bands with the transmitter in the drill head prior to drilling. Installing Batteries / Power On Page 57 Above Ground (Pre-Bore) Tilt Method Do not roll the transmitter more than two clock positions (CP) during this procedure. 1. Place the transmitter on an approximately level surface (0±10°) for at least five seconds with the receiver at the Locate screen and transmitter data being displayed. 2. Tilt the transmitter up at approximately 65° (over 100%, or nearly vertical). 3. Hold the transmitter steady for 10–18 seconds. 4. Return the transmitter to level within 10 seconds. 5. After 10–18 seconds, all transmitter data disappears from the receiver’s screen, indicating the transmitter frequency has changed. 6. Select the new frequency band in the receiver's Transmitter Options menu. The new band displays at the top of the Main menu. It may take up to 30 seconds for the transmitter to begin sending data on the new frequency; return to the Locate screen and verify that transmitter data appears on the display.

DIGITAL CONTROL INCORPORATED DigiTrak Falcon F2 Operator’s Manual 67 Appendix C: Projected Depth Versus Actual Depth and the Fore/Aft Offset What Happens When the Transmitter Is Steep and Deep The signal field emitted by the transmitter consists of a set of elliptical signals, or “flux lines”. The flux lines indicate the position of the transmitter. When the transmitter is level with respect to the ground, the locate line (LL) is directly over the transmitter, the depth displayed on the receiver is the actual depth, and the locate points (FLP and RLP) are at equal distances from the transmitter. The location of the LL is found at the intersection of the ground and the horizontal component of the flux field; the FLP and RLP are found where the vertical components of the flux field intersect with the ground. Some of the horizontal and vertical components are identified below by short yellow lines. Side View of Flux Field and Geometry of FLP, RLP, and LL Due to the shape of the transmitter’s signal field, when it is at a pitch greater than ±10% (±5.7°) and/or a depth of 4.6 m or more, the position of the locate line will be some distance ahead of or behind the transmitter’s actual position. In this case, the depth displayed on the receiver becomes what is called the projected depth. The transmitter’s distance ahead of or behind the locate line is called the fore/aft offset. The projected depth and fore/aft offset must be accounted for when the transmitter is steep and/or deep. See Table C1 and Table C2 to determine the actual depth and fore/aft offset when you know the displayed (projected) depth and pitch of the transmitter. FLP LL RLP
DIGITAL CONTROL INCORPORATED 68 DigiTrak Falcon F2 Operator’s Manual Side View of Actual Depth due to Fore/Aft Offset When Steep and Deep The above figure shows a transmitter positioned in a drill string that is drilling at either a positive or a negative pitch—the pitch is positive if you are drilling left to right, negative if you are drilling right to left. The transmitter’s signal field is also pitched at the same angle as the transmitter. The locate line (LL), which is where the depth measurement is taken, is the horizontal component of the transmitter’s signal field flux lines. That is, the LL is found where the flux lines are horizontal, illustrated by short horizontal yellow lines above. The locate points (FLP and RLP) are also shown above. These points are located at the vertical components of the signal field illustrated by short vertical yellow lines above. Note how the locate points are not the same distance from the LL when the transmitter is pitched. Again, this situation requires compensation for the projected depth and the fore/aft offset. Using the following tables to find:  actual depth based on the receiver’s depth reading (projected depth) and the transmitter pitch – Table C1  fore/aft offset based on the receiver’s depth reading (projected depth) and the transmitter pitch – Table C2  projected depth that you will see on the receiver during drilling if you know the required depth (actual depth) of your installation – Table C3  conversion factors for determining the projected depth from the actual depth, or the actual depth from the projected depth at various transmitter pitches – Table C4 These "steep and deep" calculations for projected depth are important when using a bore plan that has specified target depths on steeper and deeper bores.

For example, if you have a required (actual) depth of 7.32 m and want the receiver’s projected depth reading at a 30% (17°) pitch, use the first row of conversion factors to select the corresponding value for a pitch of 30%, which is 1.06. Multiply this value by the required depth of 24. The result, 7.75 m, is what the receiver’s projected depth reading should be at the locate line. Using the projected depth displayed on the receiver, you can calculate the actual depth of the transmitter using the second row of conversion factors. For example, if your pitch is 30% and your projected depth reading is 7.32 m, multiply depth 24 by conversion factor 0.943. The result, 6.90 m, is the actual depth of the transmitter.
DIGITAL CONTROL INCORPORATED DigiTrak Falcon F2 Operator’s Manual 71 Appendix D: Calculating Depth Based on Distance Between FLP and RLP If you know the transmitter pitch, the positions of the front locate point (FLP) and the rear locate point (RLP), and if the ground surface is level, you can still estimate the transmitter depth even if the depth information displayed on the receiver becomes unreliable. To estimate the transmitter depth, first measure the distance between the FLP and the RLP. The pitch of the transmitter must also be reliably known. Using the Depth Estimation Table below, find the divider that most closely corresponds to the transmitter pitch. Then use the following formula to estimate the depth: Depth = Distance between FLP and RLP / Divider For example, if the transmitter pitch is 34% (or 18.8°) then the corresponding divider value (from the table) is 1.50. In this example, the distance between the FLP and the RLP is 3.5 m.

In addition, DCI warrants that each DCI software product will perform in substantial accordance with the specifications set forth in the documentation for such software for the Warranty Period specified below. The following limited warranty (“Limited Warranty”) is made solely to and for the benefit of the first end-user (“User”) purchasing the DCI product from either DCI or a dealer expressly authorized by DCI to sell DCI products (“Authorized DCI Dealer”) and is not assignable or transferable. The foregoing Limited Warranty is subject to the following terms, conditions and limitations: 1. A Warranty Period of twelve (12) months shall apply to the following new DCI products: receivers/locators, remote displays, battery chargers and rechargeable batteries, and software programs and applications.

User agrees to carefully evaluate the suitability of the DCI product for User’s intended use and to thoroughly read and strictly follow all instructions supplied by DCI (including any updated DCI product information which may be obtained from the DCI website).

User agrees that the following will render the above Limited Warranty void: (i) alteration, removal or tampering with any serial number, identification, instructional, or sealing labels on the DCI product, or (ii) any unauthorized disassembly, repair or modification of the DCI product. In no event shall DCI be responsible for the cost of or any damage resulting from any changes, modifications, or repairs to the DCI product not expressly authorized in writing by DCI, and DCI shall not be responsible for the loss of or damage to the DCI product or any other equipment while in the possession of any service agency not authorized by DCI.

DIGITAL CONTROL INCORPORATED 2 DigiTrak Falcon F2 Operator’s Manual - Warranty DCI reserves the right to make changes in design and improvements upon DCI product from time to time, and User understands that DCI shall have no obligation to upgrade any previously manufactured DCI product to include any such changes. THE FOREGOING LIMITED WARRANTY IS DCI’S SOLE WARRANTY AND IS MADE IN PLACE OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, IMPLIED WARRANTY OF NON-INFRINGEMENT, AND ANY IMPLIED WARRANTY ARISING FROM COURSE OF PERFORMANCE, COURSE OF DEALING, OR USAGE OF TRADE, ALL OF WHICH ARE HEREBY DISCLAIMED AND EXCLUDED. If DCI has substantially complied with the warranty claim procedures described below, such procedures shall constitute User’s sole and exclusive remedy for breach of the Limited Warranty. Limitation of remedies and liability In no event shall DCI or anyone else involved in the creation, production, or delivery of the DCI product be liable for any damages arising out of the use or inability to use the DCI product, including but not limited to indirect, special, incidental, or consequential damages, or for any cover, loss of information, profit, revenue or use, based upon any claim by User for breach of warranty, breach of contract, negligence, strict liability, or any other legal theory, even if DCI has been advised of the possibility of such damages. In no event shall DCI’s liability exceed the amount User has paid for the DCI product. To the extent that any applicable law does not allow the exclusion or limitation of incidental, consequential or similar damages, the foregoing limitations regarding such damages shall not apply. This Limited Warranty gives you specific legal rights, and you may also have other rights which vary from state to state. This Limited Warranty shall be governed by the laws of the State of Washington. Warranty claim procedures 1. If you are having problems with your DCI product, you must first contact the Authorized DCI Dealer where it was purchased. If you are unable to resolve the problem through your Authorized DCI Dealer, contact DCI’s Customer Service Department in Kent, Washington, USA at 1.800.288.3610 (or, for international markets, the corresponding telephone number for that market) between 6:00 a.m. and 6:00 p.m. Pacific Time and ask to speak with a customer service representative. Prior to returning any DCI product to DCI for service, you must obtain a Return Merchandise Authorization (RMA) number. Failure to obtain an RMA may result in delays or return to you of the DCI product without repair. 2. After contacting a DCI customer service representative by telephone, the representative will attempt to assist you in troubleshooting while you are using the DCI product during actual field operations. Please have all related equipment available together with a list of all DCI product serial numbers. It is important that field troubleshooting be conducted because many problems do not result from a defective DCI product, but instead are due to either operational errors or adverse conditions occurring in User’s drilling environment. 3. If a DCI product problem is confirmed as a result of field troubleshooting discussions with a DCI customer service representative, the representative will issue an RMA number authorizing the return of the DCI product and will provide shipping directions. You will be responsible for all shipping costs, including any insurance. If, after receiving the DCI product and performing diagnostic testing, DCI determines the problem is covered by the Limited Warranty, required repairs and/or adjustments will be made, and a properly functioning DCI product will be promptly shipped to you. If the problem is not covered by the Limited Warranty, you will be informed of the reason and be provided an estimate of repair costs. If you authorize DCI to service or repair the DCI product, the work will be promptly performed and the DCI product will be shipped to you. You will be billed for any costs for testing, repairs and adjustments not covered by the Limited Warranty and for shipping costs. In most cases, repairs are accomplished within 1 to 2 weeks. 4. DCI has a limited supply of loaner equipment available. If loaner equipment is required by you and is available, DCI will attempt to ship loaner equipment to you by overnight delivery for your use while your equipment is being serviced by DCI. DCI will make reasonable efforts to minimize your downtime on warranty claims, limited by circumstances not within DCI’s control. If DCI provides you loaner equipment, your equipment must be received by DCI no later than the second business day after your receipt of loaner equipment. You must return the loaner equipment by overnight delivery for receipt by DCI no later than the second business day after your receipt of the repaired DCI product. Any failure to meet these deadlines will result in a rental charge for use of the loaner equipment for each extra day the return of the loaner equipment to DCI is delayed. Product demonstrations DCI personnel may be present at a jobsite to demonstrate basic usage, features, and benefits of DCI products. User acknowledges that DCI personnel are present only to demonstrate a DCI product. DCI does NOT provide locating services or other consulting or contracting services. DCI does not assume any duty to train User or any other person, and does not assume responsibility or liability for the locating or other work performed at a jobsite at which DCI personnel or equipment are or have been present.
