7. Press the keypad calibration axis I button. Press the keypad rise or lower calibration beam buttons to raise or lower the laser beam. Ensure that the beam is exactly halfway between A and B. 8. Mark this calibrated point on the vertical surface, as C. 11. Compare the height of C with D. If the heights match, calibration is complete. Proceed to step 13. If the heights do not match, proceed to step 12. 12. Press the calibration axis II button. Press the keypad raise or lower calibration beam buttons to raise or lower the laser beam until it matches the height of C. Calibration is complete. 50 ft (15m) 50 ft (15m) 9. Rotate the tool back 180° (same position as step 4). Locate the laser beam on the same vertical wall. It should coincide with C. Repeat this step until the beam is at the height of C. 10. Place the tool with the side marked II toward the wall. Position the unit such that Line II is square (90°) to the wall. Mark the laser beam height on the vertical surface, as D. 13. Simultaneously press the keypad calibration axis I and II buttons. Hold for three to five seconds, then release when you hear two beeps, signalling the exit of calibration mode. 14. Turn off the tool, then turn it back on again to resume normal operation. Using the Remote Control / Receiver-Detector The following diagram illustrates RCR2's LCD The GRL145HV can also display icon be operated using the RCR2 Remote Control / Detector LCD Display Receiver. Its receiving (detecting) function CAL CAL responds better to the GRL145HV laser tools rather than any other laser receiver-detector. The RCR2 allows accurate laser beam detection outdoors or under other conditions when the beam is difficult to see.
