Detector Controls (fig. 1)
The detector is controlled by the power button (e)
and the volume button (f).
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 Berner 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
The magnets (h) allow the detector to be mounted
to the metal tracks during the installation of a
suspended ceiling.

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.
