for use with non-rotating lasers but is compatible with most rotary
red-beam or infra-red (invisible) beam lasers on the market. It can
be set to indicate the location of the beam to either the nearest 1/8"
or the nearest 1/25". The detector gives both visual signals through
the display window (B) and audio signals through the speaker (E)
to indicate the location of the laser beam.
The D WALT digital laser detector can be used with or without the
E
detector clamp. When used with the clamp, the detector can be
positioned on a grade rod, leveling pole, stud or post.
BATTERIES
The digital laser detector is powered by a 9 volt battery. To install
the battery provided, lift up on the battery compartment cover (F).
Place the 9 volt battery in the compartment, aligning the battery
as shown on the embossed icon (I).
DETECTOR CONTROLS
The detector is controlled by the power/volume button (C) and the
accuracy mode button (D). When the power/volume button is
pushed once, the detector is turned on. The top of the display win-
dow shows the on icon (J), and the volume icon (K). 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
ital 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.
J
L
When the detector is on, the bottom of the window shows an accu-
racy mode icon. Either the ±1/25" accuracy mode icon (L) will
appear, or the ±1/8" accuracy mode icon (M) will appear. When the
±1/25" 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 1/25" above or below it. When the 1/8"
accuracy mode icon appears, it indicates that the detector will
give an "on grade" reading when the laser beam is on grade or
approximately 1/8" above or below it. Push the accuracy mode
button (D) once to change the accuracy mode.

Detector Operation
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.
