Powering the GL 1 – GL is shipped with a rechargeable NiMH battery pack, it is keyed to prevent mis-insertion. 2 – The rechargeable battery pack can be charged inside of the unit 3 – Alkaline batteries can be used as a backup 4 – Plus and minus symbols at the battery door indicate how to put the alkalines into the battery compartment Installing Batteries Remove the battery door by turning the center screw 90° counterclockwise.
Recharging the Batteries The laser is shipped with a rechargeable NiMH-battery pack. Note: The battery LED shows the approximate charge of the batteries. The LED will flash when battery voltage is between 3.8 and 4.0 volts. The LED will be on continuously when battery voltage is less than 3.8 volts. The charger requires approx. 13 hours to charge empty rechargeable batteries. For charging, connect the plug of the charger to the recharge jack of the unit.
RC402N Radio Remote Control 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 transmitter’s displays show the following information: The transmitter and remote’s display show Pairing OK for one second and then the same information as shown at the laser’s LCD to indicate the transmitter has been matched with the remote control.
Fingerprint function at the HL760 receiver Fingerprinting makes sure the HL760 detects only the laser beam of the paired tarnsmitter. Laser fingerprinting is automatically activated and confirmed with a clock symbol after a HL760 has been paired with the laser. To recognize an ignore laser strikes from other than the paired transmitter takes typically 5 seconds; sometimes few seconds more.
Features and Functions Standard Display The remote control mirrors the functionality of the laser keypad Battery status laser Mask mode indication M-Button: Quickly press and release starts the MENU entry and can be used to return to the previous menu position E-Button: Quickly press and release starts the selected mode Manual Button: Quickly press and release activates/deactivates the manual mode Up/Down Arrow Buttons Left/Right Arrow Buttons ON/OFF button - press for 1 second to turn on the unit; press an
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 horizontal lines next to the axes symbols and a M. In Manual mode (horizontal), the Y-axis can be sloped by pressing the Up- and DownArrow buttons on the laser‘s keypad or the remote control. Additionally, the X-axis can be sloped by pressing the Left- and Right-Arrow buttons on the laser or remote control.
Activating/Deactivating Standby mode Press and hold the Manual button at the laser or remote control for 3 seconds activates the Standby mode. The self-leveling will be stopped and the beam will be turned off while the HI alert is still active. The display shows Standby and the HI/MAN-LED flashes red every 5 seconds. To deactivate Standby mode and restore full operation of the laser, press and hold the Manual button at the laser or remote control again for 3 seconds.
Menu Functions Press and release M button at the Standard Display to enter the MENU. The menu offers always only the features which can be selected depending on the setup (horizontal or vertical). The actual available function will be marked in arrow brackets >> <<. A down arrow at the the right site indicates that the user can scroll down through the menu using the down arrow button.
Y-X-grade entering Step and Go mode Quickly press and release button M opens the menu. >>Grade<< will be shown. Press/release button E Both grade values will be shown. Press/release M button escape/return to the standard display.
Y-X-grade entering Digit Select mode (Default) Quickly press and release button M opens the menu. >>Grade<< will be shown. Press/release button E Both grade values will be shown and a cursor flashes at the +Y sign. Press/release M button escape/return to the standard display. Pressing and releasing Right or Left button moves the cursor to the right/left and in a circle to the next row. Use Down or Up button to change the sign (grade reverse) and set the desired digit.
Selecting the Rotation speed Quickly press and release button M opens the menu. Repeatedly press the down arrow button until >>Rotation<< will be marked. Press/release button E Both rotation values will be shown. Repeatedly pressing buttons Up/Down toggles between 300 and 600 rpm (Default) regardless if the unit is in automatic or manual mode. Quickly press and release button E to confirm the selected rotation speed.
Automatic PlaneLok mode 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 or slope positions, PlaneLok can be used on the Z- (only GL422N) or X-axis. 1. Set up the laser over the reference point. 2. Attach the HL760 receiver to a grade rod.
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 buttons. 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).
Info Press and release the M button at the Standard Display and select >>Info<<. Up and Down Buttons can be used to toggle between About LS, Runtime and Radio Press and release button E to confirm the selection. The laser information (software version, serial number.), the runtime of the GL or the radio channel will be displayed. Service Press and release the M button at the Standard Display and select >>Service<<.
Setting Menu Press and release the M button at the Standard Display and select >>Settings<<. Press and release button E to open the Setting Menu; select the desired function then press button E to open the selected submenu function OR start the selected function.

Troubleshooting Any error message can be deleted with a short press of button E. The table shows the related description and possible solutions. The next service center should be contacted if a different error message as shown at the table will be displayed.
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. Set the grade to 0.000% in both axes. 4. 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. 5.
PROTECTING THE UNIT Do not expose the unit to extreme temperatures or temperature changes (do not leave inside the car). The unit is very robust and can resist damage if dropped even from tripod height. Before continuing your work, always check the leveling accuracy. See Checking Calibration section. The laser is water proof and can be used indoors and outdoors. CLEANING AND MAINTENANCE Dirt and water on the glass parts of laser or prism will influence beam quality and operating range considerably.
