How to Use the Laser System Laser Powering the Laser Batteries Depending on the laser system configuration that you purchase, the laser is shipped with either rechargeable nickel-cadmium (Ni-Cd) or nickel/metal-hydride (Ni-MH) batteries. Even if you buy a laser that uses Ni-Cd batteries, you can upgrade to Ni-MH batteries. The upgrade installation, however, must be performed by an authorized service center. Alkaline batteries can also be used as a backup; however, rechargeable batteries should be reinstalled in the laser as soon as possible. To let you know when the batteries are getting low, the status LED flashes. When the status LED flashes yellow, the laser has less than one hour of running time. When the status LED remains on solid yellow, the batteries have less than five minutes running time. After shipment, the batteries may not have enough power to operate the system. Be sure to recharge the batteries before use. The intelligent recharger maximizes battery life and reduces the time before battery replacement by precisely controlling the recharging/discharging cycle and by not overcharging the batteries. The maximum time to achieve a full charge is six hours. Recharging the Batteries Note: Do not recharge alkaline batteries. Trying to recharge them does not damage the laser but the batteries do not recharge. 1. Plug the 4-socket plug into the laser and tighten the retaining collar. 2. Plug the supplied grounded electrical power cord into the battery-recharger. 3. Plug the grounded electrical power cord into an appropriate outlet. Note: The recharging status is indicated on the recharger. Left LED Right LED Recharging Status Off Off No connection or no batteries
Off On Recharging is in progress Flashing Off Recharging is complete Flashing Flashing Recharging error Note: The laser will not operate while the batteries are recharging. Note: Some countries or local areas have regulations regarding the disposal of rechargeable batteries. Please be sure to follow the regulation in your area. Installing/Removing the Batteries CAUTION: The batteries should be removed when storing the laser more than 30 days. 1. Remove the four screws from the battery housing. Remove the battery-housing compartment. 2. Install/remove the batteries. Note: When installing the batteries, be sure to note the positive (+) and negative (-) diagram inside of the housing. Note: The laser has reverse polarity protection. If the batteries are put in wrong, no damage occurs to the laser but it does not work. Allow it one minute to recover after the batteries have been installed correctly. 3. Put the battery-housing compartment in place and reinstall the four screws. External Power Cable The laser system also includes an external power cable so you can operate the laser in case the internal batteries become discharged. The internal batteries will not recharge, however, while you’re using the external power cable. Connecting/Disconnecting the External Power Cable CAUTION: To avoid damaging the laser, make sure the laser is off before connecting/disconnecting the external power cable to/from the laser. 1. Connect the alligator clips to a 12-V dc automotive or motorcycle battery noting the correct polarity (red = positive, black = negative). 2. Plug the 4-socket plug into the laser and tighten the retaining collar. 3. To disconnect the external power cable from the laser, loosen the retaining collar, unplug the 4-socket plug from the laser, and remove the alligator clips from the battery.
Learning Basic Laser Functions Turning On/Off the Laser 1. Press the power button to turn on the laser. Note: The laser always powers up in the automatic self-leveling mode. If the laser is out of its self-leveling range and remains out of it for more than 30 minutes, the laser shuts down completely. Note: When the laser is initially turned on, the LCD shows the approximate charge of the batteries, the laser beam’s rotation speed, and manual axis-alignment position if it’s other than zero. After the LCD shows this information, the last-entered grade immediately appears in the LCD. The status LED flashes green to indicate that the laser is self-leveling. After the laser has self-leveled at the indicated grade, the laser beam rotates and the status LED stops flashing. Note: After the laser has been level for more than 30 minutes, the HI alert activates. If the laser is disturbed (tripod bumped, etc.) so that when it re-levels the laser beam elevation changes by more than 1/8 in. (3.1 mm), the HI alert shuts down the laser and rotor, and the status LED flashes red two times per second (twice the manual-mode rate). 2. To turn off the laser, press and hold the power button for three seconds. Selecting the Rotation Speed The laser has three laser beam rotation speeds—300, 600, and 900 rpm. The rotation speed can be changed at any time to meet your job-site conditions. Use 600 rpm for held-held receivers and most machine-control systems. 1. Repeatedly press and release the rotation-control button until the desired rotation speed appears in the LCD. Note: The selected rotation speed briefly appears in the LCD. After a few seconds, the selected percentage of grade appears in the LCD. Changing the Grade Value The grade value for both axes can be changed using two methods—standard and quick-change. The standard method is used for entering small changes in the grade value. The quick-change method is used for setting grade to zero and entering large changes in the grade value.
Standard Method Note: The grade value can be quickly set to 0.000% by simultaneously pressing and releasing the up and down buttons for the axis you want to change. 1. Press and hold the up or down button for the axis you want to change until the correct grade value appears in the laser’s LCD. Note: The speed of the grade value change increases with the amount of time the button is held down. Note: Grade values from -0.500 to 9.999% are displayed in thousandths of a percents. Grade values greater than 10% are displayed in hundredths of a percent. Note: All changes to the axis-alignment rotation made prior to changing the grade value using the standard method are retained. Quick-Change Method Note: The grade value can be quickly set to 0.000% by simultaneously pressing and holding the up and down buttons for the axis you want to change 1. Simultaneously press and hold the up and down buttons for the axis you want to change to set the grade value to 0.000%. Note: The grade value for the ∠ axis increases in 1.00% increments. The grade value for the ∠ axis increases in 5.00% increments. 2. Continue pressing and holding the up and down buttons until the correct grade value appears in the laser’s LCD. Note: When the grade value for either axis reaches its highest amount, the grade value switches to the lowest value for that axis. In the ∠ axis, for example, the value switches from +10.00% to –10.00%. In the ∠ axis, the value switches from 25.00% to -0.500%. For steep-grade lasers, the value switches from 110.00% to -0.500%. Note: All changes to the axis-alignment rotation made prior to changing the grade value using the quick-change method are cancelled. Activating/Deactivating Manual Mode Manual mode bypasses the laser’s automatic self-leveling mode so you can use the laser in vertical mode. Manual mode also allows you to tilt the laser
beyond its built-in sloping capability so you can perform steep-sloping horizontal applications. 1. Make sure the laser is on and in the orientation appropriate for your application needs (horizontal or vertical). 2. Press the manual mode button. Note: When manual mode is activated, the status LED flashes red once per second and scrolling horizontal segments appear in the LCD. 3. To resume automatic self-leveling mode, press the manual button again. Rotating the Axis Alignment Manually The axes-alignment buttons allow you to electronically rotate the laser so that the grade of the laser beam properly aligns to the job-site grade. 1. To make coarse adjustments, look through the sighting guides on top of the laser and turn the laser on the tripod until it is properly aligned. 2. To make fine adjustments, press and hold the axis-alignment button that corresponds to the direction you want to rotate the laser’s axis until the desired rotation has been reached. Note: A vertical line in the LCD moves to the left or right to give you a rough indication of the rotation position.
One-Way and Two-Way Radio Remote Controls (Available for Radio-Equipped Lasers Only) Powering the Radio Remote Control Batteries CAUTION: The batteries should be removed when storing the radio remote control more than 30 days. Installing/Removing the Batteries 1. Turn the battery-housing knob counterclockwise to release the battery-housing door. 2. Install/remove the batteries. Note: When installing the batteries, be sure to note the positive (+) and negative (-) diagram inside of the housing. Note: The radio remote control has reverse-polarity protection. If the batteries are put in wrong, no damage occurs to the radio remote control but it does not work. Allow it one minute to recover after the batteries have been installed correctly. 3. Put the battery-housing door in place and turn the battery-housing knob clockwise. Learning Basic Radio Remote Control Functions The radio remote control is a hand-held device that allows you to send operational commands to the laser from a remote location. While using the radio remote control, make sure its antenna is pointing skyward. For example, if you’re holding the radio remote control in your hand and using it in the horizontal orientation, the antenna should be at a 90º angle to the radio remote control. If you’re connecting the radio remote control to a grade rod and the radio remote control is oriented vertically, the antenna should be sticking up from the top of the radio remote control. Turning On/Off the Radio Remote Control 1. Press the power button to turn on the radio remote control. Note: When the two-way radio remote control is initially turned on, the axes symbols and last-entered grade for each axis briefly appear in the LCD.

3. Press the enter button to confirm the selected rotation speed. Changing the Grade Value The grade value for both axes can be changed using two methods—standard and quick-change. The standard method is used for entering small changes in the grade value. The quick-change method is used for setting grade to zero and entering large changes in the grade value. Standard Method Note: The last-entered grade value for each axis appears in the two-way radio remote control’s LCD. If you are using a one-way remote control, you must look at the laser’s LCD for this information. Note: The grade value can be quickly set to 0.000% by simultaneously pressing and releasing either the laser’s or the radio remote control’s up and down buttons for the axis you want to change. 1. Select the desired grade axis (∠ or ∠) from the menu using the mode button. 2. Press and hold the up or down button for the axis you want to change until the desired grade value appears in the laser’s LCD. If you are using a two-way radio remote control, this information appears in the radio remote control’s LCD. Note: The speed of the grade value change increases with the amount of time the button is held down. Note: Grade values on the radio remote control are displayed in thousandths of a percents. Note: All changes to the axis-alignment rotation made prior to changing the grade value using the standard method will be retained. Quick-Change Method 1. Select the desired grade axis (∠ or ∠) from the menu using the mode button. 2. Simultaneously press and hold the up and down buttons for the axis you want to change to set the grade value to 0.000%. Note: The grade value for the ∠ axis increases in 1.00% increments. The grade value for the ∠ axis increases in 5.00% increments. 3. Continue pressing and holding the up and down buttons until the desired grade value appears in the laser’s LCD. If you are using a two-way radio
remote control, this information also appears in the radio remote control’s LCD. Note: When the grade value for either axis reaches its highest amount, the grade values switches to the lowest value for that axis. In the ∠ axis, for example, the value switches from +10.00% to –10.00%. In the ∠ axis, the value switches from 25.00% to –0.500%. For steep-grade lasers than value switches from 110.0% to –0.500%. Note: All changes to the axis-alignment rotation made prior to changing the grade value using the quick-change method will be cancelled out. Activating/Deactivating Manual Mode Manual mode bypasses the laser’s automatic self-leveling mode so you can use the laser in vertical mode. Manual mode also allows you to tilt the laser beyond its built-in sloping capability so you can perform steep-sloping horizontal applications. 1. Press the manual mode button.

Press the enter button to confirm the selection. Note: While the system is aligning, “Start” followed by “Wait” appears in the radio remote control’s LCD. 4. When the alignment has been completed, “Complete” appears in the radio remote control’s LCD. Note: Alignment can take one to five minutes to complete.
Activating/Deactivating Standby Mode Standby mode, which can only be activated by using a one-way or two-way radio remote control, is a power-saving feature that conserves laser battery life. 1. Quickly press and release the radio remote control’s power button again to activate standby mode. Note: When standby mode is activated, the laser beam, rotor, self-leveling system, and LEDs shut down. So that you know that the laser is in standby mode rather than being turned off, dashed lines appear in the laser’s LCD. In the radio remote control’s LCD, the word “standby” appears. 2. To deactivate standby mode and restore full operation of the laser, quickly press and release the radio remote control’s power button. The laser and all other functions turn on again.
System Setup General Setup Information • Prior to beginning work, decide where to place the laser for optimum coverage of the job site. • Place the laser on the job site where it will be out of the way of traffic and will not be obstructed by equipment with respect to the machine-mounted receiver. • Set the height of the tripod and laser so that the laser beam will strike the receiver when it’s positioned correctly on a machine or grade rod. • Adjust the laser’s alignment to the job site as needed. • When using the radio remote control, make sure the radio remote control’s antenna is pointing skyward and the laser’s antenna is flipped up. An “R” appears in the right corner of the remote’s first display line indicating a connection has been made and the power is on. • When the radio remote control and laser are “linked,” a flashing bar above the “T” (antenna icon) appears in the right corner of the radio remote control LCD. • The laser-beam operating radius for the standard laser models is 1,500 feet (460 m). • The laser-beam operating radius for the long-range mode is 2,500 feet (7600 m). • The radio-remote-control operating radius for the standard operating modes is 750 feet (230 m). The operating radius for the radio remote control in automatic alignment modes is 500 feet (150 m). Getting Connected Laser Connecting the Laser to a Tripod All lasers have a 5/8-11 tripod mount on the bottom of the laser so you can connect the laser to a standard tripod, column clamp, or other mounting device. The laser can also be used without a tripod, but the laser must be set on a stable surface.
In addition to using the laser in horizontal mode, you can use it in vertical mode. To do so, however, an after-market vertical mounting bracket is needed. For instruction on how to use the vertical mounting bracket, consult the specific manufacturer’s instructions. 1. Insert the tripod’s 5/8-11 screw into the laser’s threaded 5/8-11 tripod mount. 2. Turn the screw counterclockwise to hold the laser securely in place. 3. To detach the laser from the tripod, turn the screw clockwise. Connecting the Laser to the Adapters Depending on the laser system you purchase, additional mounting accessories may be shipped with your laser. The long-range (agricultural) laser system includes a quick-disconnect adapter and a 3 1/2-8 adapter. The steep-grade laser system includes a steep-grade adapter and offset plate. Quick-Disconnect and 3 1/2-8 Adapters 1. Thread the appropriate adapter into the 5/8-11 threaded mount on the bottom of the laser. Note: The carrying case is designed so the adapter can remain on the laser. Steep-Grade Adapter and Offset Plate 1. Set up a tripod so that its mounting surface is as close to true level as possible. Make sure that one of the tripod legs is aligned to the down-grade side of the ∠ axis of the laser. 2. Connect the offset plate to the steep-grade adapter. 3. Connect the steep-grade adapter (with laser and offset plate connected) to the tripod. 4. Adjust the slope knob on the steep-grade adapter to the desired grade. Align the adapter to the desired steep-slope direction hub. 5. Thread the offset plate into the 5/8-11 threaded mount on the bottom of the laser. Make sure the offset plate is connected at the mark that indicates the desired grade. Radio Remote Control
Connecting the Remote Holster to a Grade Rod 1. Wrap the mounting strap around the grade rod and fasten it securely in place. Connecting the Radio Remote Control to the Remote Holster 1. Slip the radio remote control mounting clip into the mounting slot of the remote holster. Setting Up the Laser System Setting Up the Laser in Manual Mode 1. Press the manual mode button on the laser or radio remote control. Note: When manual mode is activated, the laser’s status LED flashes red at a 1-Hz rate and scrolling horizontal segments appear in the laser’s LCDs. If you are using a two-way radio remote control, this information also appears in the radio remote control’s LCD. 2. To adjust the laser in the ∠ axis so that the laser beam matches the desired slope, use the up and down buttons on the laser or radio remote control. 3. To adjust the laser in the ∠ axis so that the laser beam matches the desired slope, use the up and down buttons on the laser or the left and right buttons on the radio remote control. 4. To resume automatic self-leveling mode, press the manual button on the laser or radio remote control again. Aligning the Axis Manually The manual axis alignment buttons are primarily used on lasers that don’t have radio remote control capability. These buttons rotate the grade axis electronically (simulates turning the laser on its tripod, with fine adjustment capability up to a maximum of ±40 degrees). 1. Set up the laser over a reference point. Make sure the laser is positioned so that the ∠ and ∠ axes are pointing in the right direction. 2. Using the sighting guides as guide, rotate the laser on its tripod to align the laser to the direction hub.
3. Connect a receiver to a grade rod and turn on the receiver. Make sure you position the receiver so that it is at the correct elevation for the distance (and grade) from the laser to the direction hub. 4. Set the grade rod on the direction hub. Note: If only one person is manually aligning the laser, use a bipod (commonly used with prism poles) to keep the grade rod plumb when placing is on the direction hub. 5. Press the appropriate manual axis alignment button to align the laser plane to the receiver. The clockwise axis alignment button rotates the laser clockwise; the counterclockwise axis alignment button rotates the laser counterclockwise. 6. Press and hold the axis alignment button until you get an on-grade reading on the receiver. Setting Up the Laser in Vertical Mode 1. Set up the laser on its side. Note: If you’re using the laser with a tripod, an after-market vertical mounting bracket is needed. For instruction on how to use the vertical mounting bracket, consult the specific manufacturer’s instructions. 2. Press the manual button on the laser or radio remote control. 3. To adjust the laser beam for line direction, use the up and down buttons on the laser or radio remote control until the laser beam matches the line point. 4. To adjust the plumb position of the laser beam, use the up and down buttons on the laser or the left and right buttons on the radio remote control. Establishing Control Determining Height of Instrument (HI) 1. Set up the laser and turn it on. 2. Connect a receiver to a grade rod. Turn on the receiver. 3. Place the grade rod on a job-site benchmark (BM). Adjust the height of the receiver until the receiver’s LCD shows an on-grade reading. 4. Add the grade-rod reading to the benchmark to determine the height of instrument. Use the HI as a reference for all other elevation measurements.
Establishing Elevation Control Hubs The elevation control hub can be used to re-establish the elevation of the laser plane in case the laser setup gets disturbed. 1. Establish an elevation-control hub close to the laser and determine the HI. Note: If you’re also going to establish a grade control hub, make sure the elevation-control hub and grade -control hubs are on the same axis. Establishing Grade Control Hubs The slope control hub can be used to check the alignment of the laser on the job site and to confirm the grade entered into the laser. 1. Check the grade on a minimum of three hubs on the job site. The hubs should be in lines that are 90° from one another with one line containing two hubs. Note: Because the accuracy of this procedure is based on the known elevation of the hubs, the exact elevation of the hubs is critical. Note: If there isn’t enough space for the laser to be setup on the desired centerline, the laser can be set up on a line parallel to the centerline (D1-D2).
Reversing the Grade (One-Way and Two-Way Radio Remote Controls) The sign of the ∠ axis can be changed using the one-way or two-way radio remote control. 1. Set up the laser. Turn on the laser and flip its antenna up. 2. Turn on the radio remote control and make sure its antenna is pointing skyward. 3. Select “Grade Reverse” from the menu using the mode button. 4. Press the enter button to confirm the selection. Note: On a one-way radio remote control, “Reversing” appears in the radio remote control’s LCD to indicate that the process is occurring and the sign of the ∠ axis will be changed on the laser’s LCD. Note: When grade reversing has been completed, “Grade Reversing Complete” appears in the LCD. If “Grade Reversing Unconfirmed” appears in the LCD, check the distance between the laser and radio remote control and try reversing the grade again. Note: On a two-way radio remote control, the sign of the ∠ grade value reverses to indicate that grade reversing has been completed.
Automatic Alignment Modes Summary The laser system has three automatic alignment modes: • Axis Alignment • Grade Matching • PlaneLok To use these modes, a radio remote control (one-way or two-way) and hand-held receiver are required. The radio remote control and receiver are typically mounted to a grade rod, which must be placed somewhere between 60 feet (20 m) and 500 feet (150m) from the laser. Automatic axis alignment can take from 1 to 5 minutes to complete. Automatic Axis Alignment Mode This automatic axis alignment function replaces the manual alignment scope and vernier base traditionally used to align the desired grade axis to a hub. When this mode is being used, the receiver and radio remote control are mounted to a grade rod, the desired grade is dialed into the laser, and the grade rod is placed on the hub that the grade axis is being aligned to. When activated, automatic axis alignment mode adjusts the direction the desired grade axis is pointing to by electronically simulating “rotating” the laser on its mounting base. This mode is typically used for agriculture, road construction, and steep-grade applications where precision alignment of the grade axis is required. Grade-Matching Mode This automatic alignment function changes the grade of the desired axis to automatically match an unknown grade. When this mode is being used, the receiver and radio remote control are mounted to a grade rod, the approximate grade (within 1.5% of the actual grade) is dialed into the laser, and the grade rod is benchmarked to the laser-beam elevation at a point within 3 feet (1 m) of the laser. Without changing
the receiver’s elevation on the rod, the grade rod is then placed anywhere a grade reading is needed. When activated, grade-matching mode automatically adjusts the grade up or down to “search” for the receiver. When the center of the receiver is found, the resultant grade is calculated and dialed into the laser, and displayed on the two-way radio remote control (if being used). When grade matching is complete, the receiver can be removed from the alignment point and the calculated grade will remain in the laser. Both axes of the laser can be grade matched in sequence. Grade-matching mode is used for applications where the existing grade is not known, but will remain relatively unchanged (such as installation of a sidewalk or driveway). PlaneLok Mode PlaneLok mode works like grade-matching mode, except the receiver is permanently mounted to the desired elevation so that the laser can use the receiver to continually monitor beam elevation. The laser ignores the internal level vial for that axis, using the absolute elevation from the receiver for level control. PlaneLok Mode is used for applications where extreme precision of the laser-beam elevation is required, such as runway applications.
Using Axis-Alignment and Grade-Reverse Modes How Axis-Alignment Mode Works Axis-alignment mode works by changing grade in the aligned-axis direction and cross-axis directions then monitoring the elevation changes of the laser beam at the receiver via the radio remote control. The desired axis-alignment angle can then be calculated and the internal grade system “rotated” electronically to align the simulated grade axis to the desired point. Important Things to Know about Automatic Axis Alignment Automatic Axis Alignment • Replaces the alignment scope and vernier base traditionally used • Can be done from any side of any axis of the laser, even if grade is dialed into the opposite axis that’s being aligned • Automatically adjusts the direction the grade axis is pointing to the receiver/remote location • Electronically simulates rotating the laser on its base to match the hub For Proper Operation • The desired grades must be entered into the laser • The receiver must be at the correct alignment point • The receiver must be between 60 feet (20 m) and 500 feet (150 m) from the laser For Best Accuracy • Set up the laser to align to the elevation reference the farthest away (such as the centerline of the road) • If the hubs are equally distant, align to the hub with the smallest amount of grade Practical Application for Automatic Axis Alignment and Grade Reverse Modes: Road Construction Setup
The main uses for the laser in road construction are for planar sections where the road design calls for no vertical or super-elevated curves. Automatic Axis Alignment Mode 1. Set up the laser over a point on the centerline of the road. 2. Using the sighting guide as a guide, rough align the laser with the direction hub on the centerline. Note: Because the laser can provide positive and negative slopes in the ∠ axis, make sure the laser’s handle is at a 90° angle to the centerline of the road. Note: If there isn’t enough space for the laser setup on the centerline, the laser can be set up on a line parallel to the centerline of the road (D1=D2). 3. Enter the grade value for the axis that aligns with the centerline of the road (∠). 4. Enter the grade value for the side of the road to be graded first into the axis that is perpendicular to the centerline of the road (∠). 5. Connect a receiver and radio remote control to a grade rod. 6. Set the grade rod on the centerline direction hub. 7. Slide the receiver up/down the grade rod until the receiver’s LCD shows an on-grade reading. Note: The grade rod MUST be plumb. 8. Select “Axis Align” from the operational menu using the radio remote control’s mode button. 9. Select the axis (∠ or ∠) that you are aligning using the up or down buttons. 10. Press the enter button to confirm the selection. “Start” then “Wait” appears on the LCD. 11. Hold the grade rod plumb and steady during automatic axis alignment. Note: Alignment can take from 1 to 5 minutes to complete. Note: When axis alignment has been completed, “Axis Alignment Complete” appears in the LCD. If axis alignment fails, a failure message appears in the LCD. 12. Check the laser’s alignment and grade values using previously established elevation-control hubs and slope-control hubs as references.
Note: If the alignment and grade values need small adjustments, they can be changed using the radio remote control. See the “Correcting Slope/Height Differences” section of this manual for more information. 13. Grade that side of the road
Grade Reverse Mode Note: After you’ve finished grading one side of the road, you can reverse the sign of the ∠ axis from the cab using the radio remote control. 1. Set the blade on a known elevation hub on the centerline of the road. 2. Select “Grade Reverse” from the operational menu using the radio remote mode button. 3. Press the enter button to confirm the selection. Note: On the one-way radio remote control, “Reversing” appears in the radio remote control’s LCD to indicate that the process is occurring and the sign of the axis will be changed. Note: When grade reversing has been completed, “Grade Reversing Complete” appears in the LCD. If “Grade Reversing Unconfirmed” appears in the LCD, check the distance between the laser and radio remote control and try reversing the grade again. Note: On a two-way radio remote control, the sign of the grade display reverses to indicate that grade reversing has been completed. Practical Application for Axis Alignment Mode: Steep Grades Setup (Embankments, Waste Dumps and Sea Walls) 1. Set up a tripod on an established offset from the baseline of the bank to make sure that the laser beam will be at the required height above the bank surface. Make sure that one of the tripod legs is aligned with the down-grade side of the ∠ axis. 2. Connect the steep-grade adapter to the tripod. 3. Adjust the steep-grade adapter to the desired grade value. 4. Align the adapter with the direction hub on the top of the bank. 5. Connect the laser to the steep grade adapter making sure that the laser’s handle is parallel with the baseline of the bank. 6. Make sure the desired slope and rotation speed are entered into the laser. 7. Using the sighting guides as a guide, rough align the laser with the direction hub. 8. Connect a receiver and radio remote control to a grade rod. 9. Set the grade rod on the direction hub. 10. Slide the receiver up/down the grade rod until the receiver’s LCD shows an on-grade reading.
Note: The grade rod MUST be plumb. 11. Select “Axis Align” from the operational menu using the radio remote control’s mode button. 12. Select the axis (∠ or ∠) that you are aligning using the up or down buttons. 13. Press the enter button to confirm the selection. “Start” then “Wait” appears on the LCD. 14. Hold the grade rod plumb and steady on the direction hub. Note: Alignment can take 1 to 5 minutes to complete. Note: When axis alignment has been completed, “Axis Alignment Complete” appears in the LCD. If axis alignment fails, a failure message appears in the LCD. 15. Check the laser’s alignment using previously established direction hub and baseline hubs as references. Note: If the alignment and grade values need small adjustments, they can be changed using the radio remote control. See the “Correcting Slope/Height Differences” section of this manual for more information. Note: If the axis alignment should be done to the baseline hub #2 (perpendicular to the steep grade axis), attach the offset plate to the steep grade adapter so that the rotor head of the laser is at the same axis as the tripod mount. Follow the steps as described above with the only change that the axis alignment using the grade rod has to be done at baseline hub #2 (steps 7, 9, and 14) instead of the direction hub.
Using Grade-Matching Mode How Grade-Matching Mode Works Grade-matching mode works by changing grade in the selected axis direction then monitoring the elevation changes of the laser beam at the receiver via the radio remote control. Once the laser “finds” the center of the receiver, the resultant grade is calculated and stored in the laser and two-way remote control. Important Things to Know about Grade-Matching Mode Grade-Matching Mode • Automatically adjusts the grade of the selected axis to match an unknown grade • Searches for and finds “on-grade” of the mounted receiver within a 1.5% grade range of the final grade (starting with the beam centered on the receiver isn’t necessary) • Stores and displays the resultant grade on the remote and laser For Proper Operation • The receiver can be removed after alignment, and the resultant grade remains in the laser • One or Both axes can be grade matched in sequence • The initial grade MUST be within 1.5% of the final grade before starting Practical Application for Grade-Matching Mode, One-Axis Setup: General Construction Setup If the ∠ axis is not at 0% grade, the laser has to be aligned in automatic axis alignment mode with control hub #2 before the grade-matching mode can be activated. 1. Set up the laser over the reference point. 2. Using the sighting guide as a guide, rough align the laser with slope-control hub #2.
Note: The laser and control hub #1 must be on one axis, which is at 0% grade. 3. Enter the approximate grade value for the ∠ axis and 0% for the ∠ axis. Note: The automatic slope-searching range is ±1.5%. The approximated grade should be within 1.5% of the final matched grade. 4. Connect a hand-held receiver and radio remote control to a grade rod. 5. Set the grade rod on control hub #1. 6. Slide the receiver up/down the grade rod until the receiver’s LCD shows an on-grade reading. Note: The grade rod MUST be plumb. 7. Go to slope-control hub #2 and set the grade rod on the hub. Make sure you DON’T change the height of the receiver on the grade rod. 8. Select “Grade Match” from the operational menu using the mode button. 9. Select the axis (∠ or ∠) that you are aligning using the up or down buttons. 10. Press the enter button to confirm the selection. “Start” then “Wait” appears in the radio remote control LCD. 11. Hold the grade rod plumb and steady on slope-control hub #2 during grade matching. Note: “Grade Matching Complete” appears in the radio remote control LCD when grade matching has been completed. If grade matching fails, a failure message appears in the radio remote control LCD. (See the “Troubleshooting” section of this manual for more information.) Note: The resultant grade appears in the laser LCD display and on the two-way remote control LCD display (if used). Note: Alignment can take 1 to 5 minutes to complete. Grade-Matching Mode: Two Axes Setup This function can only be done on one axis at a time. The laser needs to be aligned with one of the slope-control hubs in automatic axis alignment mode before dual axes grade-matching mode can be activated. 1. Set up the laser over a reference point. 2. Using the sighting guide as a guide, rough align the laser with the slope-control hub #1. Note: The two slope-control hubs must be in lines that are at a 90° angle from one another.
Note: The laser and the elevation-control hub must be on one axis. 3. Enter the approximate grade value for the ∠ axis and the ∠ axis. Note: The automatic slope searching range is ±1.5%. The approximated grade should be within 1.5% of the final matched grade. 4. Connect a hand-held receiver and radio remote control to a grade rod. 5. Set the grade rod on the elevation-control hub. 6. Slide the receiver up/down the grade rod until the receiver’s LCD shows an on-grade reading. Note: The grade rod MUST be plumb. 7. Determine the HI by using the elevation-control hub as a reference. 8. Go to slope-control hub #1 and set the grade rod on the hub. Make sure you DON’T change the height of the receiver on the grade rod. 9. Select “Grade Match” from the operational menu using the mode button. 10. Select the axis (∠ or ∠) that you are aligning using the up or down buttons. 11. Press the enter button to confirm the selection. “Start” then “Wait” appear in the LCD. 12. Hold the grade rod plumb and steady on slope-control hub #1 during grade matching. Note: “Grade Matching Complete” appears in the radio remote control LCD when grade matching has been completed. If grade matching fails, a failure message appears in the radio remote control LCD. (See the “Troubleshooting” section of this manual for more information.) Note: The matched grade value for the aligned axis appears in the laser’s and two-way radio remote control’s LCDs. Note: Alignment can take 1 to 5 minutes to complete. 13. Go to slope-control hub #2 and set the grade rod on the hub. Make sure you DON’T change the height of the receiver on the grade rod. 14. Select “Grade Match” from the operational menu using the mode button. 15. Select the axis (∠ or ∠) that you are aligning using the up or down buttons. 16. Press the enter button to confirm the selection. 17. Hold the grade rod plumb and steady on slope-control hub #2 during grade matching. Note: “Grade Matching Complete” appears in the radio remote control LCD when grade matching has been completed. If grade matching fails, a failure message appears in the radio remote control LCD. (See the “Troubleshooting” section of this manual for more information.)
Note: The matched grade value for the aligned axis appears in the laser’s and two-way radio remote control’s LCDs. Note: Alignment can take 1 to 5 minutes to complete.
Using PlaneLok Mode How PlaneLok Mode Works PlaneLok mode works by changing grade in the selected axis direction then monitoring the elevation changes of the laser beam at the receiver via the radio remote control. Once the laser “finds” the center of the receiver, it continues to monitor its position and makes small corrections to hold the beam on-grade. Important Things to Know about PlaneLok Mode • Loss of receiver signal results in laser “out of level” mode (no laser beam or rotation) • The internal laser level vial for that axis is ignored (the receiver is used for level control) • The opposite axis levels to its internal level vial and grade PlaneLok • Works like grade match mode, except the receiver is permanently mounted at the desired elevation to continually monitor beam elevation • Is used for applications requiring extreme accuracy, such as in runway applications For proper operation • The initial grade MUST be within 1.5% of the final grade before starting Practical Application for PlaneLok Mode: Agricultural and Runway Applications Agriculture and runway applications can generally be handled using any of the previously described processes. For extremely accurate agriculture or runway applications whose work-time extends over several days or even weeks, PlaneLok mode is recommended. PlaneLok Mode Setup 1. Set up the laser over a reference point.
2. Using the sighting guide as a guide, rough align the laser with one of the slope-control hubs. Note: The two slope-control hubs must be in lines that are at a 90° angle from one another. 3. Enter the approximate grade into the axis that needs to be aligned and an exact grade value into the other axis. Note: The automatic slope searching range is ±1.5%. The approximated grade should be within 1.5% of the final matched grade. 4. Connect a receiver and radio remote control to a grade rod. 5. Set the grade rod on the elevation-control hub. 6. Slide the receiver up/down the grade rod until the receiver’s LCD shows an on-grade reading. Note: The grade rod MUST be plumb. 7. Go to the slope-control hub on the axis to be aligned and set the grade rod on the hub. Make sure you DON’T change the height of the receiver on the grade rod. 8. Select “PlaneLok” from the operational menu using the mode button. 9. Select the axis (∠ or ∠) that you are aligning using the up or down buttons. 10. Press the enter button to confirm the selection. “Start” then “Wait” appears in the LCD. Note: Note: When the PlaneLok function has been completed, “PlaneLok Complete” and a “Lock” icon (padlock symbol) appear in the radio remote control LCD. Note: Alignment can take 1 to 5 minutes to complete. Note: If the PlaneLok function fails, the remote indicates the cause of failure. See the ‘Troubleshooting” section of this manual for more information. Note: The receiver should be permanently mounted at this location and at the desired elevation. Use a bipod (commonly used with prism poles) to hold the grade rod steady for the entire workday. Note: The resultant grade on the locked axis is displayed in the remote LCD. Note: The laser continues to servo to the receiver’s elevation signals. Any loss of signal over an extended period of time (1 minute) causes the laser beam to turn off and rotor to stop. The PlaneLok mode must be reactivated when the laser experiences loss of signal over an extended period.
Using the Radio Remote Control to Correct Slope/Height Differences after Setup Sometimes, after performing any of the advanced alignment functions, the alignment and grade values need small adjustments. These adjustments can be made using a one-way or two-way radio remote control. One-Way Remote Checking Slope/Height Differences for the ∠ and ∠ Axes 1. Determine the height of the laser (HI) by setting the grade rod on elevation-control hub #1. 2. Check the HI by setting the grade rod on elevation-control hub #2. Make sure you DON’T change the height of the receiver on the grade rod. Adjusting Slope/Height Differences for the ∠ and ∠ Axes Small differences of the slope/height can be corrected using the up and down buttons in 0.01% using “Grade Bump” mode. 1. Select “∠ Grade Bump” from the operational mode menu using the radio remote control’s mode button. 2. Press the up or down button on the radio remote control until you get an on-grade reading on the receiver. Each press of the up/down button increases/decrease grade in .01% increments. To change the grade by 0.05%, for example, press and release the button five times. 3. Go to the elevation-control hub for the ∠ closed axis and set the grade rod on the hub. Make sure you DON’T change the height of the receiver on the grade rod. 4. Select “∠ Grade Bump” from the operational menu using the radio remote control’s mode button. 5. Press the up or down button on the radio remote control until you get an on-grade reading on the receiver. Each press of the up/down button increases/decrease grade in .01% increments. To change the grade by 0.05%, for example, press and release the button five times. Two-Way Remote Checking Slope/Height Differences for the ∠ and ∠ Axes

Maintenance and Care You will get years of service from the leveling system by following the maintenance and care recommendations in this manual. Carry the laser in its moisture-resistant, field-tested carrying case to safely move the laser from one job to another. However well the product is designed, mishaps do occur. The most common problems associated with these are covered in the following areas. Storage CAUTION: Do not store the laser in a wet carrying case. If the case gets wet, open it and let it dry before storing the laser. CAUTION: Remove the batteries from the laser and receiver when storing the equipment more than 30 days. Battery Disposal Some countries, states, and local areas have regulations regarding the disposal of rechargeable batteries. Be sure that replaced batteries are disposed of properly. System Cleaning Use only a good-quality glass cleaner and a soft cloth to clean all external optical components. A dry cloth used on the laser’s/radio remote control’s optical components or displays could scratch or damage these surfaces. Blow off any loose debris before cleaning any surfaces to prevent scratching of optical surfaces. Monthly, wipe off with a moist, clean cloth any dust or dirt from the laser’s outer surface, inside the battery housing, and within the leveling base. Clean all corroded battery contacts with a pencil eraser or baking soda solution.
Troubleshooting If none of the following techniques corrects the problem, take your system to a local Trimble dealer or authorized service center for evaluation or repair. Laser Problem Solution Laser will not turn on • Make sure the batteries have sufficient power and are installed correctly. • Make sure the batteries contacts are in proper working condition. No signal is received at the receiver • Make sure the receiver is turned on. • Make sure the batteries have sufficient power and are installed correctly. • Make sure the laser is sending out a beam. • Check for a laser signal with another receiver. No laser beam • Make sure the laser is on. • Make sure the batteries have sufficient power and are installed correctly. • Make sure that the laser is within its self-leveling range (up to 25%). • Switch the laser into manual mode; the laser should come on. The battery life is short • Make sure high-quality batteries are being used. • When recharging the batteries, make sure the charger is plugged into an appropriate ac outlet. The batteries require a minimum charge time of six hours.
Radio remote control is not working with the laser • Make sure the antenna is upright. • If the remote does not work with the laser, the remote needs to be “matched” to the laser for proper operation. Return the laser to an authorized service center for the matching procedure to be performed. Laser beam not accurate • Check and adjust calibration as needed. • Return the laser to an authorized service center for inspection.
Receiver Problem Solution Receiver does not receive a laser signal • Make sure the laser receiver is on. • Make sure the batteries have sufficient power and are installed correctly. • Make sure the batteries contacts are in proper working condition. • Make sure the receiver is within the operating range of the laser. • Try receiving the laser beam with another receiver. If the new receiver detects the laser beam, return the original receiver to an authorized service center for repair. Receiver occasionally beeps when it is not in the laser beam • Make sure the receiver is not near radar or high-frequency radio stations. • Make sure the laser beam is not bouncing off a highly reflective surface. Radio Remote Control Problem Solution Radio remote control not receiving or sending any signal • Make sure the radio remote control is on. • Make sure the batteries have sufficient power and are installed correctly. • Make sure the batteries contacts are in proper working condition. • Make sure you have a good connection between the receiver and radio remote control. • Make sure the radio remote control antenna is mounted

Laser Error Messages The laser has error codes that indicate either a hardware or software problem. If one of the following codes appears in the laser’s LCD, please return the laser to an authorized Trimble service center: • 0004 • 0008 • 0010 • 0020 • 0040 • 0080 • 0100 • 0200 • 0400 • 0800 • 1000 • 2000 • 4000 • 8000 For more information about returning the laser to a service center, please see the “Request for Service and Parts” section of this manual.
Calibration As with any precision instrument, the calibration needs checking on a regular basis (such as the beginning of each job, or if the laser has been handled roughly). If the laser is to be used below freezing, be sure to check calibration under those conditions. The laser has a calibration error when the laser plane coming out one side of the laser is above true level, and the laser plane coming out the opposite side is below true level. Adjusting the position of the laser plane requires making minor adjustments the leveling mechanism using the up and down buttons on the control panel. When the laser is properly calibrated, it emits a 360° horizontal level plane so that if the laser is turned 180° or 90° from its original position, the reading is within ±5/16 in. per 300 ft (±8 mm/90 m) of the original position. To check the horizontal calibration, you’ll need a tripod with a 5/8-11 threaded mount and a hand-held receiver. If you need to adjust the calibration, having another person to help saves time. Checking Calibration 1. Set up the laser 300 ft (90 m) from a wall. 2. Set the grade to 0.000% in both axes. 3. Raise/lower the receiver until you get an on-grade reading for the +∠ axis. Using the on-grade marking notch as a reference, make a mark on the wall. Note: For increased precision, use the fine-sensitivity setting (+1/16 in./+1.6 mm) on the receiver. 4. Rotate the laser 180° (–∠ axis toward the wall) and allow the laser to re-level. 5. Raise/lower the receiver until you get an on-grade reading for the –∠ axis. Using the on-grade marking notch as a reference, make a mark on the wall. 6. Measure the difference between the two marks. If they differ more than 5/16 in. (8 mm), the laser needs calibrating. Adjusting the Calibration at the Laser
1. Position the receiver at the midpoint of the two marks on the wall. 2. Add/subtract grade in the appropriate axis using the up/down buttons. The grade appears in the LCD. Note: The up/down buttons needed to calibrate the ∠ axis on single slope lasers are “hidden” behind the control panel. 3. When the beam is centered in the receiver, use the following “hidden” button sequence to store the new calibration value and to zero out the grade display: a) Press and hold the manual button b) Quickly press and release the power button (do NOT press the power button long enough to turn off the laser c) Press and release the up button for the ∠ axis d) Release the manual button e) The grade display will zero out to indicate calibration is complete. 4. Rotate the laser 180° back to the original face. Make sure this axis is less than 5/16 in. (8 mm) from the midpoint line. Note: If additional adjustment is required, repeat steps 1-3 above. 5. After adjusting the ∠ axis, rotate the laser 90°. Repeat the above starting with the –∠axis facing the wall. Adjusting the Calibration Using the Radio Remote Control 1. Position the receiver at the midpoint of the two marks on the wall. 2. Add/subtract grade in the appropriate axis using the grade increase/decrease modes (one-way radio remote control: Grade Bump; two-way radio remote control: Grade Change). 3. When the beam is centered on the receiver’s LCD, use the following radio remote control button sequence to store the new calibration point and to zero out the grade display: f) Turn off the radio remote control g) Press and hold the manual button h) Turn on the radio remote control. “Calibration” appears in the LCD. i) Press the enter button to confirm the selection. j) The grade display on the laser and two-way radio remote control will zero out to indicate calibration is complete. 4. Rotate the laser 180° back to the original face. Make sure this axis is less than 5/16 in. (8 mm) from the midpoint line.
Note: If additional adjustment is required, repeat steps 1-3 above. 5. After adjusting the ∠ axis, rotate the laser 90°. Repeat the above starting with the –∠axis facing the wall.

The carrying case is designed to that the adapter can remain attached to the laser while the laser is being stored in the case. Steep-Grade Adapter
The steep-grade adapter allows the internal leveling mechanism of the steep-grade laser to level the laser at grades greater than 25%. Offset Plate The offset plate mounts to the steep-grade adapter and eliminates offset errors when the laser is being used for steep-grade applications by maintaining the laser’s rotor position over the laser’s mounting threads. This adapter HAS to be used when performing a steep-grade axis alignment that is perpendicular to the steep-grade axis. How to Use the Laser System Laser Powering the Laser Batteries Depending on the laser system configuration that you purchase, the laser is shipped with either rechargeable nickel-cadmium (Ni-Cd) or nickel/metal-hydride (Ni-MH) batteries. Even if you buy a laser that uses Ni-Cd batteries, you can upgrade to Ni-MH batteries. Alkaline batteries can also be used as a backup; however, rechargeable batteries should be reinstalled in the laser as soon as possible. Installing/Removing the Batteries CAUTION: The batteries should be removed when storing the laser more than 30 days. 1. Remove the four screws from the battery housing. Remove the battery-housing compartment. 2. Install/remove the batteries. Note: When installing the batteries, be sure to note the positive (+) and negative (-) diagram inside of the housing. Note: The laser has reverse polarity protection. If the batteries are put in wrong, no damage occurs to the laser but it does not work. Allow it one minute to recover after the batteries have been installed correctly. 3. Put the battery-housing compartment in place and reinstall the four screws.
To let you know when the batteries are getting low, the status LED flashes. When the status LED flashes yellow, the laser has less than one hour of running time. When the status LED remains on solid yellow, the batteries have less than five minutes running time. Connecting the Laser to a Tripod All lasers have a 5/8-11 tripod mount on the bottom of the laser. Depending on the laser system you purchase, additional mounting adapters may be shipped with your laser. The long-range (agricultural) laser system includes a quick-disconnect adapter and a 3 1/2-8 adapter. The steep-grade laser system includes a steep-grade adapter and offset plate. The laser can also be connected to a standard tripod, column clamp, or other mounting device. If you’re using the laser without a tripod, however, make sure you set the laser on a stable surface. 1. Insert the tripod’s 5/8-11 screw into the laser’s threaded 5/8-11 tripod mount. 2. Turn the screw counterclockwise to hold the laser securely in place. 3. To detach the laser from the tripod, turn the screw clockwise. Turning On/Off the Laser 1. Press the power button to turn on the laser. Note: The laser always powers up in the automatic self-leveling mode. If the laser is out of its self-leveling range and remains out of it for more than 30 minutes, the laser shuts down completely. Note: When the laser is initially turned on, the LCD shows the approximate charge of the batteries, the laser beam’s rotation speed, and manual axis-alignment position if it’s other than zero. After the LCD shows this information, the last-entered grade immediately appears in the LCD. The status LED flashes green to indicate that the laser is self-leveling. After the laser has self-leveled at the indicated grade, the laser beam rotates and the status LED stops flashing. Note: After the laser has been level for more than 30 minutes, the HI alert activates. If the laser is disturbed (tripod bumped, etc.) so that when it re-
levels the laser beam elevation changes by more than 1/8 in. (2.5 mm), the HI alert shuts down the laser and rotor, and the status LED flashes red two times per second (twice the manual-mode rate). 2. To turn off the laser, press and hold the power button for three seconds. Selecting the Rotation Speed The laser has three laser beam rotation speeds—300, 600, and 900 rpm. The rotation speed can be changed at any time to meet your job-site conditions. Use 600 rpm for held-held receivers and most machine-control systems. The rotation speed can also be changed using either of the radio remote controls. The rotation speed appears in the two-way radio remote control’s LCD. If you’re using a one-way radio remote control, you must look at the laser’s LCD for this information. For more information about using the radio remote control, see the operator’s manual. 1. Repeatedly press and release the rotation-control button until the desired rotation speed appears in the LCD. Note: The selected rotation speed briefly appears in the LCD. After a few seconds, the selected percentage of grade appears in the LCD. Changing the Grade Value The grade value for both axes can be changed using two methods—standard and quick-change. The standard method is used for entering small changes in the grade value. The quick-change method is used for setting grade to zero and entering large changes in the grade value. The grade value can also be changed using either of the radio remote controls. The grade value appears in the two-way radio remote control’s LCD. If you’re using a one-way radio remote control, you must look at the laser’s LCD for this information. For more information about using the radio remote control, see the operator’s manual. Standard Method
Note: The grade value can be quickly set to 0.000% by simultaneously pressing and releasing the up and down buttons for the axis you want to change. 1. Press and hold the up or down button for the axis you want to change until the correct grade value appears in the laser’s LCD. Note: The speed of the grade value change increases with the amount of time the button is held down. Note: Grade values from -0.500 to 9.999% are displayed in thousandths of a percents. Grade values greater than 10% are displayed in hundredths of a percent. Note: All changes to the axis-alignment rotation made prior to changing the grade value using the standard method are retained. Quick-Change Method 1. Simultaneously press and hold the up and down buttons for the axis you want to change to set the grade value to 0.000%. Note: The grade value for the ∠ axis increases in 1.00% increments. The grade value for the ∠ axis increases in 5.00% increments. 2. Continue pressing and holding the up and down buttons until the correct grade value appears in the laser’s LCD. Note: When the grade value for either axis reaches its highest amount, the grade value switches to the lowest value for that axis. In the ∠ axis, for example, the value switches from +10.00% to –10.00%. In the ∠ axis, the value switches from 25.00% to -0.500%. For steep-grade lasers, the value switches from 110.00% to -0.500%. Note: All changes to the axis-alignment rotation made prior to changing the grade value using the quick-change method are cancelled. Activating/Deactivating Manual Mode Manual mode bypasses the laser’s automatic self-leveling mode so you can use the laser in vertical mode. Manual mode also allows you to tilt the laser beyond its built-in sloping capability so you can perform steep-sloping horizontal applications. Manual mode can also be activated/deactivated using either of the radio remote controls. The words “Manual Mode” appear in the two-way radio remote control’s LCD when manual mode is activated. If you’re using a one-
way radio remote control, you must look at the laser’s LCD for this information. For more information about using the radio remote control, see the operator’s manual. 1. Make sure the laser is on and in the orientation appropriate for your application needs (horizontal or vertical). 2. Press the manual mode button. Note: When manual mode is activated, the status LED flashes red once per second and scrolling horizontal segments appear in the LCD. 3. To adjust the laser in the ∠ axis so that the laser beam matches the desired slope or grade, use the ∠ axis up and down buttons on the laser or radio remote control. 4. To adjust the laser in the ∠ axis so that the laser beam matches the desired slope or grade, use the ∠ axis up and down buttons on the laser or the left and right buttons on the radio remote control. 5. To resume automatic self-leveling mode, press the manual button on the laser or radio remote control again. Aligning the Axis Manually The manual axis alignment buttons rotate the grade axis electronically (simulates turning the laser on its tripod, with fine adjustment capability up to a maximum of ±40 degrees). 1. Set up the laser over a reference point. Make sure the laser is positioned so that the ∠ and ∠ axes are pointing in the right direction. 2. Using the sighting guides as guide, rotate the laser on its tripod to align the laser to the direction hub. 3. Turn on the laser and allow it to self-level. 4. Connect a receiver to a grade rod and turn on the receiver. Make sure you position the receiver so that it is at the correct elevation for the distance (and grade) from the laser to the direction hub. 5. Set the grade rod on the direction hub. Note: If only one person is manually aligning the laser, use a bipod (commonly used with prism poles) to keep the grade rod plumb when placing is on the direction hub.
6. Press the appropriate manual axis alignment button to align the laser plane to the receiver. The clockwise axis alignment button rotates the laser clockwise; the counterclockwise axis alignment button rotates the laser counterclockwise. 7. Press and hold the axis alignment button until you get an on-grade reading on the receiver. Radio Remote Control (One-Way and Two-Way) The radio remote control is a hand-held device that allows you to send operational commands to the laser from a remote location. These operational commands include changing grade values, rotation speed, and operating modes. The radio remote control HAS to be used for the following advanced alignment features: • Automatic Axis Alignment • Grade Reverse • Grade Matching • PlaneLok See your operator’s manual for detailed setup and operation of these advanced features. A solid “T” symbol appears in the right corner of the LCD to indicate that the link between the radio remote control and laser is complete. A flashing bar above the “T” indicates that communication with the laser is established. When the radio remote control is connected to a receiver, an “R” appears in the right corner of the radio remote control’s first display line indicating that a connection has been made and the power is on. When using the radio remote control, make sure its antenna is pointing skyward. Turning On/Off the Radio Remote Control 1. Press the power button to turn on the radio remote control. Note: When the two-way radio remote control is initially turned on, the axes symbols and last-entered grade for each axis briefly appear in the LCD. 2. To turn off the radio remote control, press and hold the power button for 3 seconds.
Selecting the Operational Mode The mode button allows you to choose the laser’s operational mode, which includes changing grade, automatic axis alignment, grade matching, PlaneLok, grade bump, grade reverse, manual, and beam rotation speed. 1. Repeatedly press and release the mode button to cycle through the operational menu. The menu selections appear in the radio remote control’s LCD.
