dry—away from direct sunlight and excess heat 
or cold.
Detector Troubleshooting
THE DETECTOR WILL NOT TURN ON
  •  Press and release the power button.
  • Check to see that the battery is in place and 
in the proper position.
  •  If the detector is very cold, allow it to warm up 
in a heated area.
  •  Replace the 9-volt battery. Turn the unit on.
  •  If the detector still does not turn on, take the 
detector to a DEWALT service centre.
THE DETECTOR’S SPEAKER MAKES NO SOUND
  •  Ensure that the detector is on.
  •  Press the volume button. It will toggle on and 
off.
  •  Ensure that the laser is turned on and that it is 
emitting a laser beam.
  •  If the detector is still not making any sound, 
take it to a DEWALT service centre.
THE DETECTOR DOES NOT RESPOND TO THE BEAM FROM 
ANOTHER LASER UNIT
 • The DEWALT Digital Laser Detector has been 
designed to work only with the DW088 and the 
DW089 and certain other compatible line lasers.
THE DETECTOR GIVES OFF A TONE BUT THE LCD DISPLAY 
WINDOW DOES NOT FUNCTION
  •  If the detector is very cold, allow it to warm up 
in a heated area.
  •  If the LCD display window is still not functioning, 
take the detector to a DEWALT service centre.
BRIGHT LIGHT SHINING ON DETECTOR CAUSES 
CONTINUOUS “ON-GRADE” SIGNAL
  •  In the presence of very intense ambient 
light, the detector may give a false or erratic 
indication of level.
  •  Reposition the detector out of the intense 
light or shade the sensor window (i) to resume 
normal operation.
