For charging, connect the plug of the charger to the recharge jack of the unit.
Laser Setup Position the laser horizontally (tripod mount and rubber feet downward!) on a stable platform, wall mount or tripod at the desired elevation. The laser recognizes automatically whether it is used horizontally or vertically when switched on. Turning On/Off the laser Press the power button to turn On the laser. The LEDs (b, d and e) are turned on for 3 seconds. Self-leveling will start at once. The unit is leveled when the leveling LED (d) is no longer flashing (once every second).
Standard Features Rotation Mode Rotation speed can be selected using the Rotation button as well as using the RC402N menu. Repeatedly pressing the Rotation button toggles through 0, 10, 80, 200, 600 rpm regardless if the unit is in automatic or manual mode. At 0 rpm, the beam stops automatically close to the +Y- axis center position. When set up horizontally in automatic mode, using buttons Up/Down increases/decreases the rotor speed from 10 to 80 and then continuously in 10 rpm increments up to 600 rpm.
Standard Features Manual mode Pressing and releasing Manual button activates/deactivates the manual mode regardless if set up horizontal or vertical. Manual mode is indicated by the flashing (once every second) red LED (e). In Manual mode (horizontal), the Y-axis can be sloped by pressing the Up and Down Arrow-buttons on the laser or remote control. Additionally, the X-axis can be sloped by pressing the Left and Right Arrow-buttons on the laser or the remote control.
Mask Mode Mask Mode – allows you to electronically turn off the rotating laser beam (electronic shutters) in up to 3 lighthouse windows to prevent interference with other receivers on the jobsite. Mask Mode can be selected as a standard feature as well as using the menu. To activate the mask mode on the + or -Y-axis, press the Up or Down arrow button at the laser or remote control, then within <1 second press and release the Manual button.
Applications Interior Acoustical Ceilings 1. Determine and mark the finished ceiling height and securely install the first piece of wall molding to this height. 2. Attach the laser onto the wall molding by sliding the wall mount over the wall molding and turn the locking screws until the wall mount is secured. 3. Make sure the locking knob on the wall mount is loose. 4.
Determining the Height of Instrument (HI) The height of instrument (HI) is the elevation of the laser’s beam. The HI is determined by adding the grade-rod reading to a benchmark or known elevation. Set up the laser and place the grade rod on a job-site benchmark (BM) or known elevation. Slide the receiver up/down the grade rod until it shows an on-grade reading. Add the grade-rod reading to the benchmark to determine the height of instrument. Example: Benchmark = 30.55 m (100.23 ft) Rod reading = +1.
Using the Y-Axis Single Slope Mode 1. 2. 3. 4. 5. 6. Set up the laser and align it to the desired slope hub using the sighting guides on the sunshade. Check the laser beam elevation close to the laser. To activate the Y-axis single slope mode, press the manual mode button twice. The red and green LED flashes simultaneously (once a second). Set the grade rod with the receiver attached to it on the desired slope/elevation hub.
Using the optional HL760HL760U receiver To pair the HL760/HL760U receiver with the transmitter Make sure the transmitter is turned off. First, turn on the receiver, then press and hold the Deadband (A) and Audio (B) buttons for two seconds. After two seconds, the display shows MENU first, then RDIO A Press and release the Units (C) button – display shows the current radio mode.
Special Features using the optional RC402N RC402N Features and Functions The remote control mirrors the basic functionality of the laser keypad and offers additional features using the M and E buttons.
Powering the RC402N 1. Open the battery door using a coin or similar pry device to release the battery door tab on the RC402N. RC402N will be shipped with alkaline batteries Rechargeable batteries can be used optional but need to be charged externally. 2. Insert two AA batteries noting the plus (+) and minus (-) diagrams inside the battery housing. 3. Close the battery door. Push down until it “clicks” into the locked position.
Pairing the remote control with the transmitter First, make sure the transmitter and the remote control are turned off. Then press and hold the Manual button and turn on the transmitter. During the next 6 seconds repeat the same steps on the remote control. The Laser beeps and the remote’s display shows Pairing OK for one second and then the same function as the laser is actually working to indicate the transmitter has been matched with the remote control.
Rotation Press and release the M button at the Standard Display and select >>Rotation<<. Press and release button E to display the actual rotation speed. Use the Up/Down buttons to select toggle through the pre-selected rotation speeds 0, 10, 80, 200 and 600 rpm. Confirm the desired speed by pressing the E button. At 0 rpm, the beam stops automatically close to the +Y- axis center position.
Automatic Grade Match The Grade Match mode can be activated in horizontal automatic mode. In Grade Match mode, the laser can be used to connect two known elevation points (up to 100 m (330 ft) located on the Y-axis of the laser. 1. Set up the laser over the reference point. 2. Attach the HL760/HL760U receiver to a grade rod. Check the laser’s elevation next to the laser then position the receiver at the second point WITHOUT changing the receiver’s elevation on the rod. 3.
Automatic PlaneLok The PlaneLok mode can be activated in horizontal automatic and vertical automatic and manual mode. In PlaneLok mode when set up horizontal, the beam will be locked to a fixed elevation point (up to 100 m (330 ft) located on the Y-axis of the laser. For keeping vertical alignments fixed to the direction position, PlaneLok can be used on the X-axis. 1. Set up the laser over the reference point. 2. Attach the HL760/HL760U receiver to a grade rod.
Note: In every PlaneLok mode the laser continues to servo to the receiver’s signals. Any loss of signal over an extended period of time (1 minute) causes the laser to go into the HI-alert condition (beam turns off, rotor stops and a warning message occurs at the RC402N LCD). PlaneLok mode can be reactivated after the HI-alert condition has been deleted with the E button.
Mask mode Press and release the M button at the Standard Display and select >>Mask Mode<<. Depending on which side the beam should be turned off, the required side can be selected. Press and release the E button, the mask symbol occurs. For selecting the side, press and release one of the arrow button. When all areas have been set, press button E to store the mask sector selection until the unit will be turned off. Note: The unit always powers up with the mask mode deactivated (default).
Service Press and release the M button at the Standard Display and select >>Service<<. Buttons Up/Down can be used to toggle between Calibration X and Calibration Y OR Calibration Z when set up vertically. Press and release button E to confirm the selection. The calibration at the selected axis starts the field calibration procedure. Setting Menu Press and release the M button at the Standard Display and select >>Settings<<.
Sensitivity Selection Select >>Sensitivity<< and press and release button E to open the Sensitivity menu. The desired Sensitivity: Low, Mid (Default) and High) can be selected using the Up/Down buttons. Press and release button E to confirm the selected Sensitivity.

CALIBRATION Checking Calibration of the Y- and X-Axes 1. Set up the laser 30 m (100 ft) from a wall and allow it to level. 2. Allow the unit to warm up for 20 minutes. 3. Raise/lower the receiver until you get an on-grade reading for the +Y 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 (1.5 mm/ 1/16 in.) on the receiver. 4. Rotate the laser 180° (-Y axis toward the wall) and allow the laser to re-level. 5.
Wall Mount Nail Holes (3) – allows you to hang the wall mount onto nails or screws. Locking Screws – lock/unlock the wall mount at the wall molding or floor track. 3. Locking Knob—tightens/loosens the sliding bracket in place after it has been positioned along the elevation scale. 4. 5/8“ –11 Laser Mount – lets you connect the laser to the wall mount. 5. Fine height adjustment screw—lets you fine adjust the laser’s position on the wall mount. 6.
PROTECTING THE UNIT Do not expose the unit to extreme temperatures or temperature changes (do not leave inside the car).
