Batteries (Fig. 6)

The digital laser detector is powered by a 9-volt battery. To install the

battery provided, lift up on the battery compartment cover (S). Place

the 9-volt battery in the compartment, aligning the battery as shown

on the embossed icon.

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.

– 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.

 • 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 (Y) to resume normal operation.

MAINTENANCE

To maintain the accuracy of your work, check the laser often to make

sure it is properly calibrated. See Field Calibration Check.

Calibration checks and other maintenance repairs may be performed by

DeWALT service centers.

When not in use, store the laser in the kit box provided. Do not store

your laser at temperatures below -20 °C (-5 °F) or above 60 °C (140 °F).

Do not store your laser in the kit box if the laser is wet. The laser should

be dried first with a soft dry cloth.

Field Calibration Check (Fig. 7, 8A, 8B, 9A, 9B)

The field calibration check must

be performed securely and

accurately to make a correct

diagnosis. Whenever an error

is registered, have the tool

serviced by a qualified repair

agent.

WARNING: The conditions of

the area are indicative of the

results presented. If the practice

differs from these conditions,

the measurements have to be

adjusted accordingly.

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 DeWALT digital laser detector is rain resistant but not immersible.

Do not pour water on the unit or submerge it under water.

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 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 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 center.
