The DEWALT Digital Laser Detector also has an 
auto shut-off feature. If a laser beam does not strike 
the beam detection window, or if no buttons are 
pressed, the detector will shut itself off in about 
5minutes.
To turn off the audible signal push the button again; 
the volume icon will disappear. 
The detector powers up in the narrow accuracy 
setting (icon appears in the lower left corner). Press 
the accuracy button (g) once to change to wide 
accuracy setting (icon now appears in the lower right 
corner).
Accuracy
The detector provides two accuracy settings, 
wide and narrow. In the wide setting, the detector 
provides a larger tolerance for indicating that the 
detector is “on grade”. In the narrow setting, this 
tolerance is reduced for more accurate indication of 
“on grade”.
For the most accurate results, start the work using 
the wide setting and finish in the narrow setting.
Magnets
The magnets (h) allow the detector to be mounted 
to the metal tracks during the installation of a 
suspended ceiling. 
OPERATION
Instructions for Use
   WARNING: 
  •  Always observe the safety instructions 
and applicable regulations.
  •  Before first use, remove and discard 
the protective tape from the screens.
Detector Operation (fi g. 1)
  1. Set up and position the laser. 
  2. Turn the detector on by pressing the power 
button (e).
  3. Position the detector so that the sensor 
window (i) is facing the laser beam. Move the 
detector up or down within the approximate 
area of the beam, until you have centred the 
detector. For information about the display 
window indicators and the audible signal 
indicators, refer to the table titled Indicators.

  4. Use the marking notches (d) to accurately mark 
the position of the laser beam.
Mounting on a Grade Rod (fi g. 1, 2)
  1. To secure your detector to a grade rod, first 
attach the detector to the clamp by pushing in 
on the clamp latch (j). Slide the tracks (k) on the 
clamp around the rail (l) on the detector until the 
latch (m) on the clamp pops into the latch hole 
(n) on the detector. 
  2. Open the jaws of the clamp by turning the 
clamp knob (o) counterclockwise. 
  3. Position the detector at the height needed and 
turn the clamp knob clockwise to secure the 
clamp on the rod.
  4. To make adjustments in height, slightly loosen 
the clamp, reposition and retighten.
MAINTENANCE
Your attachment has been designed to operate 
over a long period of time with a minimum of 
maintenance. Continuous satisfactory operation 
depends upon proper tool care and regular cleaning.
Detector Service
Except for batteries, there are no user serviceable 
parts in the Digital Laser Detector. Do not 
disassemble the unit. Unauthorised tampering with 
the laser detector will void all warranties.
Detector Cleaning and Storage
  •  Dirt and grease may be removed from the 
exterior of the detector using a cloth or soft, 
non-metallic brush.
