Installing a Battery in the Detector (Fig.
H
)
The Digital Laser Detector is powered by a 9 volt battery. To
install the battery provided, lift up on the battery compartment
cover
21
. Place the 9 volt battery in the compartment, aligning
the battery as shown.
Detector Controls (Fig.
I
)
The detector is controlled by the power button
26
and the
accuracy mode button
27
.
When the power button is pushed once, the detector is turned
on. The top of the display window shows the accuracy icon
27
, and the volume icon
28
. To decrease the volume of the
audible signal that the detector emits when it senses a laser
beam, push the button again; one of the half circles next to the
horn icon will dissappear. To turn off the audible signal push the
button a third time; the volume icon will dissapear. The
D
e
WALT
Digital Laser Detector also has an auto shut-off feature. If a
rotary laser beam does not strike the beam detection window,
or if no buttons are pressed, the detector will shut itself off in
about 30 minutes.
When the detector is on, the top of the window shows an
accuracy mode icon. Either the 1 mm accuracy mode icon
53
will appear, or the 3 mm accuracy mode icon
54
will appear.
When the 1 mm accuracy mode icon appears, it indicates that
the detector will give an “on grade” reading only when the
laser beam is on grade or no more than 1 mm above or below
it. When the 3 mm accuracy mode icon appears, it indicates
that the detector will give an “on grade” reading when the
laser beam is on grade or approximately 3 mm above or below
it. Push the accuracy mode button
27
once to change the
accuracy mode.
Detector Operation (Fig.
I
,
J
)
1. Set up and position the rotary laser that you will be using
according to the manufacturer’s directions. Turn the laser
on and make sure that the laser is rotating and emitting a
laser beam.
NOTE:
This detector has been designed to be
used only with a rotating laser. The detector will not work
with a stationary beam laser level.
2. Turn the detector on by pressing the power/volume
button
26
.
3. Adjust the volume as desired as described in the
Detector Controls
.
4. Position the detector so that the detector window
22
is
facing the laser beam produced by the rotary laser. 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 titled Indicators (Fig.
J
).
5. Use the marking notches
30
to accurately mark the
position of the laser beam.
Detector Cleaning and Storage
• Dirt and grease may be removed from the exterior of the
detector using a cloth or soft, non-metallic brush.
• The
D
e
WALT
Digital Laser Detector is waterproof. If you
should drop the detector in mud, wet concrete, or a similar
substance, simply hose the detector off. Do not use high
pressure water, e.g., from a pressure washer.
• 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
D
e
WALT
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
D
e
WALT
service center.
The detector does not respond to a stationary laser beam.

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
