Operating Tips
• Use only new, high-quality, name brand batteries for best results.
• Ensure batteries are in good working condition. If the low battery
red indicator light is flashing, the batteries need replacement.
• To extend battery life, turn laser off when not working with or
marking the beam.
• To ensure the accuracy of your work, check often to make sure
your laser is calibrated. See Field Calibration Check.
• Before attempting to use the laser, make sure it is positioned
securely, on a smooth, flat surface.
• Always mark the centre of the beam created by the laser.
• Extreme temperature changes may cause movement of internal
parts that can affect accuracy. Check your accuracy often while
working. See Field Calibration Check.
• If the laser has been dropped, check to make sure your laser is still
calibrated. See Field Calibration Check.
