DeWalt DW079 Guide D'utilisation page 18

The detector is not for use with non-rotating lasers but is compatible
with most rotary red-beam or infrared (invisible) beam lasers on the
market. It can be set to indicate the location of the beam to either
the nearest 1/8" (3 mm) or the nearest 1/25" (1 mm). The detector
gives both visual signals through the display window (V) and audio
signals through the speaker (W) to indicate the location of the laser
beam.
The D WALT Digital Laser Detector can be used with or without
E
the detector clamp. When used with the clamp, the detector can be
positioned on a grade rod, leveling pole, stud or post.
BATTERIES (FIG. 9)
The Digital Laser Detector is powered by a
9 volt battery. To install the battery pro-
vided, lift up on the battery compartment
cover (X). Place the 9 volt battery in
the compartment, aligning the battery as
shown on the embossed icon (Y).
DETECTOR CONTROLS (FIG. 10)
The detector is controlled by the power/
volume button (Z) and the accuracy mode
button (AA).
When the power/volume button is pushed
once, the detector is turned on. The top of
the display window shows the ON icon
(BB), and the volume icon (CC). 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 WALT Digital
E
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 bottom of the window shows an
accuracy mode icon. Either the ±1/25" (1 mm) accuracy mode icon
(AA1) will appear, or the ±1/8" (3 mm) accuracy mode icon (AA2)
will appear. When the ±1/25" (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 1/25" (1 mm)
above or below it. When the 1/8" (3 mm) accuracy mode icon
appears, it indicates that the detector will give an "on grade"
FIG. 9
reading when the laser beam is on grade or approximately 1/8"
(3 mm) above or below it. Push the accuracy mode button (AA)
once to change the accuracy mode.
X Detector Operation (Fig. 11)
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.
