Special features
The laser detector includes a rod clamp which allows to mount the detector
onto square, round or oval sighting rods.
The detectors are gasket sealed for water and dust protection. Remove any
moisture or dirt with a soft, dry cloth.
Do not use aggressive cleaning agents or solvents. Remove batteries before
storage of the instrument.
The LCD display of the detector LD-400 has seven distinct channels of infor-
mation, indicating the position of the detector in the plane of laser light, as
indicated in Fig. C (the detectors LD-120 and LD-100N have three).
As you move the detector closer to the center, the arrows fill in to indicate
the laser position.
The detector has 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.
The detector LD-400 has three speaker selections (Off, Loud (105dBA) and
Louder (125+ dBA)), whereas the models LD-120 and LD-100N have only two
(Off and On).
Power
A 9-volt battery will provide up to 3 months of typical usage. When the unit is
turned on and the low battery symbol remains lit, the battery should be
replaced.
