      Lori AdamsAug 4, 2025
      Your Datum Laser Level might not be turning on because the batteries are low, depleted, or not installed correctly. Ensure the batteries are in good working condition; if unsure, replace them with new ones, making sure to install them with the correct polarity. Also, if the laser has been stored in a hot environment, allow it to cool down before use.

      If your Datum Laser Level isn't leveling, it could be due to several reasons. First, the instrument might be outside its leveling range, so adjust its position, tripod, or base surface. Ensure the instrument is within its self-leveling range. Also, check if the instrument is in Manual Mode, as it needs to be in Automatic Mode to self-level.

      If the laser detector isn't working correctly, it might be due to low battery. Replace the batteries, ensuring they are installed with the correct polarity. Another reason could be that the detector is out of usable range; try moving the detector closer to the instrument.
