Universal Laser Detector - David White AutoLaser 3110-GR Instruction Manual

UNIVERSAL LASER DETECTOR

Introduction
The David White® Universal Laser Detector aids in locating and targeting a visible or invisible
beam emitted by a rotary laser; perfect for use in outdoor conditions, where sunlight and distance
may make locating the beam more difficult.
The laser detectors LD-12N and LD-18N include a rod clamp which allows to mount the detector
onto square, round or oval sighting rods.

Power
A 9-volt battery will provide up to 3 months of typical usage. When the instrument is turned on and
the low battery symbol remains lit, thebattery should be replaced.
Operation– Laser Detector
1: Mount the instrument onto a sighting rod if you are using one. Turn on the instrument by
pressing the ON/OFF pad. The LCD symbols will momentarily flash and the "coarse" beam
indicator symbol will remain lit and the audio signal will be on. (Fig. 21)
2: Expose the beam capture window of the laser detector towards thedirection of the
rotating laser.
3: Slowly move the laser detector in an upward and downward direction until the LCD beam
indicator arrows appear and/or a pulsing audio signal is heard. Use the Beam Resolution
feature to choose between the coarse/low setting, used forapproximating level or for initial
locating of the center level point, the medium setting, used for greater accuracy, and the
fine/high setting, used for the most accurate pinpointing of level.
4: Move the detector upward when the low beam indicator light is lit (with volume on, a slow
pulsing audio tone is heard). Move the detector downward when the high beam indicator
arrow is lit (with volume on, a rapid pulsing audio tone is heard). When the beam is level, the
level beam indicator line will be lit and a solid audio tone will be heard.
If the detector is not struck by a laser beam after 5-8 minutes, the detector will automatically shut
itself off to preserve battery life. Turn the instrument back on using the power button.
