The BTI 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 (g) 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 (fig. 1)
The magnets (h) allow the detector to be mounted
to the metal tracks during the installation of a
suspended ceiling.
OPERATION
Instructions for Use
WARNING:
• Always observe the safety instructions
and applicable regulations.
• Before first use, remove and discard
the protective tape from the screens.
Detector Operation (fig. 1)
1. Set up and position the laser.
2. Turn the detector on by pressing the power
button (e).
3. Position the detector so that the sensor
window (i) is facing the laser beam. Move the
detector up or down within the approximate
area of the beam, until you have centred the
detector. For information about the display
window indicators and the audible signal
indicators, refer to the table titled Indicators.

Mounting on a Grade Rod (fig. 1, 2)
1. To secure your detector to a grade rod, first
attach the detector to the clamp by pushing in
on the clamp latch (j). Slide the tracks (k) on the
clamp around the rail (l) on the detector until the
latch (m) on the clamp pops into the latch hole
(n) on the detector.
2. Open the jaws of the clamp by turning the
clamp knob (o) counterclockwise.
3. Position the detector at the height needed and
turn the clamp knob clockwise to secure the
clamp on the rod.
4. To make adjustments in height, slightly loosen
the clamp, reposition and retighten.
MAINTENANCE
Your attachment has been designed to operate
over a long period of time with a minimum of
maintenance. Continuous satisfactory operation
depends upon proper tool care and regular cleaning.
Detector Service
Except for batteries, there are no user serviceable
parts in the Digital Laser Detector. Do not
disassemble the unit. Unauthorised tampering with
the laser detector will void all warranties.
Detector Cleaning and Storage
• Dirt and grease may be removed from the
exterior of the detector using a cloth or soft,
non-metallic brush.
