Troubleshooting
The receiver does not pick-up the laser or performs strangely.
• Be sure the laser is transmitting a beam (if in doubt, stop the rotation
and view the laser spot on a target). Never look into the beam
output window! Make sure that the laser beam is rotating (not scanning)
and that the rotation speed is set to maximum.
• If the above does not help, try replacing the receiver battery.
The laser will not operate, there is no obvious damage.
• If the low battery indicator is on, or you suspect the batteries may be
dead, replace the batteries.
• Check the battery contacts to be sure that they are clean.
The receiver shows an on-grade at two different heights.
• Check the jobsite for windows or mirrored surfaces that might be
reflecting the laser and causing the other reading.
• Check for others on the site using a rotary laser.
The laser was knocked over.
• Visually check the optics for damage.
• Inspect the laser for any other physical damage.
• Check to see that the laser is transmitting a beam by viewing the beam
on a target. Never look into the beam output window!
• Turn the laser rotation on and check for unusual noise or vibration.
• Check the calibration and adjust as needed.
The laser only works at short distances.
• Check the output window on the rotating head of the laser for heavy
dust or moisture. Remove dust with a camera brush or blow off gently
with clean compressed air. Allow moisture to dry.
The receiver does not indicate "on grade" at long distance.
• Be sure you have not exceeded 500ft (152m) from the laser.
• Check the output window on the rotating head of the laser and the red
receiver window for dust or moisture. Remove dust with a camera
brush or gently blow with clean compressed air. Remove any moisture.
The laser shuts off after running for only a few minutes.
• If the red low battery indicator is flashing, replace / recharge batteries.
• If there is no indication at all, check for dead batteries.
