Laser Accessories
DE0892-XE DIGITAL LASER
DETECTOR (FIG. 6)
Some laser kits include a DeWALT Digital Laser detector.
The DeWALT Digital Laser Detector helps in locating a
laser beam emitted by the laser in bright light conditions
or over long distances. The detector can be used in
both indoor and outdoor situations where it is difficult to
see the laser beam.
The detector is designed exclusively for use with the DW088-XE and
the DW089-XE line lasers and other compatible DeWALT line lasers. It
is not for use with rotating lasers.
The detector gives both visual signals through the LCD display window
(Q) and audio signals through the speaker (R) to indicate the location
of the laser beam.
The DeWALT Digital Laser Detector can be used with or without the
detector clamp. When used with the clamp, the detector can be
positioned on a grade rod, leveling pole, stud or post.
FIG. 4 FIG. 5

Detector Controls (Fig.6)
The detector is controlled by the power button (U) and the volume
button (V).
When the power button is pushed once, the detector is turned on. The
top of the sensor window shows the ON icon and the volume icon.
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 5 minutes.
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 (W) 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 (X) allow the detector to be mounted to the metal tracks
during the installation of a suspended ceiling.
Detector Operation (Fig. 6)
1. Set up and position the laser.
2. Turn the detector on by pressing the power button (U).
3. Position the detector so that the sensor window (Y) is facing the
laser beam. Move the detector up or down within the approximate
area of the beam, until you have centered the detector. For
information about the display window indicators and the audible
signal indicators, refer to the table below titled Indicators.
4. Use the marking notches (T) to accurately mark the position of the
laser beam.
