• The best storage place is one that is cool and dry–away
from direct sunlight and excess heat or cold.
Detector Service
Except for batteries, there are no user serviceable parts in the
Digital Laser Detector. Do not disassemble the unit. Unauth-
orized tampering with the laser detector will void all warranties.
Detector Troubleshooting
The detector will not turn on.
• Press and release the power/volume 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 center.
The detector’s speaker makes no sound.
• Ensure that the detector is on.
• Press the power/volume button. It will toggle from high, to
low, to mute.
• Ensure that the rotary laser is spinning and that it is
emitting a laser beam.
• If the detector is still not making any sound, take it to a
DeWALT service center.
The detector does not respond to a stationary laser
beam.
• The DeWALT Digital Laser Detector has been designed to
work only with rotary 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 center.
Construction Grade Rod (Fig. L)

DANGER: NEVER attempt to use a grade rod in a storm
or near overhanging electric wires. Death or serious
personal injury will occur.
Some laser kits include a grade rod. The DeWALT Grade Rod
is marked with measurement scales on both sides and is
constructed in telescoping sections. A spring-loaded button
actuates a lock to hold the grade rod at various lengths.
The front of the grade rod has the measurement scale starting
at the bottom. Use this for measuring from the ground up
when grading or leveling jobs.
The back of the grade rod is designed to measure the height
of ceilings, joists, etc. Fully extend the top section of the grade
rod until the button locks into the previous section. Extend that
section either until it locks into the adjacent section or until the
grade rod touches the ceiling or joist. The height is read where
the last extended section exits the previous lower section, as
shown in FigureL.
Using the Laser with a Wall Mount
(Fig.C, M, N)
Some laser kits include a Wall Mount. It can be used for
attaching the tool to track or ceiling angle and to aid in
acoustical ceiling installation. Follow the directions below for
using the wall mount.

CAUTION: Before attaching the laser level to wall
track or ceiling angle, be sure that the track or angle is
properlysecured.
1. Place the laser on the mounting base
37
aligning the 5/8–
11 screw hole on the tripod adapter (
20
, Fig. C) attached to
the bottom of the laser with the hole
39
in the mounting
base. Turn the mounting knob
40
to secure the laser.
2. With the wall mount measuring scale
41
facing you,
loosen the wall mount clamp locking knob
42
to open the
clamp jaws.
3. Position the clamp jaws around the wall track or ceiling
angle and tighten the wall mount clamp locking knob
42
to close the clamp jaws onto the track. Be sure that
the wall mount clamp locking knob is securely tightened
beforeproceeding.

CAUTION: Always use a ceiling wire hanger or equivalent
material, in addition to the wall mount clamp locking
knob, to help secure the laser level while mounting it to a
wall. Thread the wire through the handle of the laser level.
DO NOT thread the wire through the protective metal
cage. Additionally, screws may be used to fasten the wall
mount directly to the wall as a back up. Screw holes
43
are located at the top of the wall mount.
4. Using the base leveling knob
44
approximate a level
position from the wall.
5. The tool can be adjusted up and down to the desired
offset height for working. To change the height, loosen
the locking knob
45
located on the left of the wall mount.
Support the mounting base when adjusting the height.
6. Turn the adjustment knob
46
, located to the right of the
wall mount, to move the laser level up and down to set
your height. Use the wall mount measuring scale
41
to
pinpoint your mark.
NOTE: It may be helpful to turn the power on and turn the
rotary head so that it puts a dot on one of the laser scales.
The DeWALT target card is marked at 1–1/2" (38 mm),
therefore, it may be easiest to set the offset of the laser to
1–1/2" (38 mm) below the track.
7. Once you have positioned the laser at the desired height,
tighten the locking knob
45
to maintain this position.
