LMH
2: Press the Power button once, and allow
time (up to 60 seconds) for the unit to selflevel. The Power On LED (Fig. 1) and the laser Fig. 1
will blink during this process. Please note, the laser head may begin to
rotate before leveling is complete. The
self-leveling speed is approximately 1° per 4 seconds.
3: After self-leveling, the laser head will rotate at 600 RPM (LMH600 will
rotate at the last selected speed. Press the Power button again to turn
the unit off. (Note: for LMH-GR and LMH600 models, see section
4.3.2 (page 11)
LMH Series Rotary Lasers • 9
3.2 Re-leveling
If the unit is bumped or moved, the unit
will automatically attempt to re-level
itself. The Power On LED and the laser
will blink during this process until the
unit is level once again. The laser head
will resume rotation.
On the job site, it may be necessary to
prevent re-leveling in order to prevent
inaccurate measurements by the operator. The LMH’s Anti-Drift System (Section
3.3) is used for this purpose.

3.2.1 Axis Drive Error
If the LMH is set up or tipped beyond its
self-leveling range of ±5°, the laser head
will initially attempt to level; however,
when the self-leveling limit is reached,
the LEDs will blink, indicating an axis
drive error (Fig. 2). Turn the LMH off,
move the unit into a more level position,
then turn the unit on again.

9. TROUBLESHOOTING
The following information lists basic tests that can be performed to
check the LMH in the event of poor performance.
Check Your Batteries: One of the most common causes of performance failures is due to defective or incorrectly installed batteries.
Check to see if any batteries are installed backwards and correct
if necessary.
• Never selectively replace batteries; always replace all of the batteries
at the same time with new batteries. It is recommended, if possible,
that the batteries be checked with a voltmeter or battery tester to
confirm proper voltage.
• Leaky batteries may have damaged the battery contacts in the
battery box.
• Check to see that the battery tray is screwed tightly onto the base of
the unit. Also, the fit between the battery prongs and the batteries
may need adjustment, as this fit may vary over different brands of
battery (especially Energizer™ brand, as they are larger in diameter,
preventing a proper connection).
• Alkaline batteries are recommended for the best performance and
storage life. Rechargeable batteries such as Nickel-Cadmium will
provide performance, but are not as desirable due to their lower
terminal voltage. Low cost standard Carbon-Zinc batteries may be
used in emergencies, but they should be replaced with alkaline
batteries when available.
Rechargeable Battery Pack: For maximum battery life, the battery
pack must contain a full charge. The batteries will begin to perform
optimally after five full charges and discharges.
Unit does not rotate or self-level, or produces Axis Drive Error: Reset the internal processor by turning power off and on again.
You may also try removing the battery tray for 15 seconds to let the
capacitor discharge, then replace the tray and try again.
If the unit rotates but does not self-level, be sure that the Anti-Drift
System is turned off.
24 • LMH Series Rotary Lasers
LMH Series Errors:
When an error occurs on the LMH Series, turn the unit OFF. Wait 15
seconds, then turn unit ON. If these procedures do not correct error,
contact CST/berger.

Electronic Laser Detector
1. INTRODUCTION
The LaserMark® Electronic 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.

4. OPERATION
1: Mount the unit onto a sighting rod if
you are using one. Turn on the unit by
pressing the ON/OFF pad. The LCD
symbols will momentarily flash (Fig. 1)
and the “coarse” beam indicator symbol
will remain lit and the audio signal will
be on.
2: Expose the beam capture window of
the laser detector towards the direction
of the rotating laser.

3: Slowly move the laser detector in an
Fig. 1
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 for approximating 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 short pulsing audio tone is heard). Move the
detector downward when the high beam indicator arrow is lit (with
volume on, a long 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 unit back on using the power button.
28 • LMH Series Rotary Lasers
5. SPECIAL FEATURES
This 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. Three distinct audio tones (high,
on-grade, and low) assist targeting from a distance.
Features speaker Off, Loud
(105 dBA) and Louder (125+
dBA), fine, medium, and coarse
beam resolution settings, and
front and back LCD displays.
Seven distinct channels of
information (Fig. 2) indicate
the position of the detector in
Fig. 2
the plane of laser light. As you move the detector
closer to the center, the arrows fill in to indicate the laser position.
