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.
Special Features– Laser Detector
The laser detectors have a unique memory feature, which preserves the last position of the laser
beam if the detector is moved out of the plane of laser light, as well as built in electronic filtering
for bright sunlight and electromagnetic interference. Three distinct audio tones (high, on-grade,
and low) assist targeting from a distance.
The detector LD-400 has three speaker selections (Off, Loud (105dBA) and Louder (125+ dBA)),
whereas the model LD-120 has only two (Off and On).
The LCD display of the detector LD-400 has seven distinct channels of information, indicating the
position of the detector in the plane of laser light (the detector LD-120 has three).
As you move the detector closer to the center, the arrows fill in to indicate the laser position (Fig. 22).
