1. BRIEF DESCRIPTION
LRM 2200SI Laser Rangefinder Monocular (the unit) is an
advanced laser range finder system that enables instant distance,
direction, elevation, azimuth and speed measurement.
The unit complies with CFR 21, Part 1040.10.
High quality multi-coated optics are combined in this device with
complex circuitry design to create a system that can outperform
other product in its class.
Principle of operation
Once activated, the unit sends invisible, eye-safe laser pulses to
the target. The pulses reflected from the target are captured and
processed internally. The unit operates based on the time-of-
flight principle meaning that range is calculated by measuring the
delay between the sent and received laser pulses.
A built-in digital inclinometer measures the elevation
simultaneously with distance measurement, in its turn elevation

measurement allows height calculation. The unit measures
azimuth simultaneously as well. Speed of an object moving
closer or further from the unit can also be calculated using the
time-of-flight principle.

Changing battery
To install a battery:
.
.
.
Slide the battery compartment cover down (Fig. 2)
Install the battery, observing correct polarity
Do not force the battery while placing back inside the
compartment.
.
Close the compartment cover
If the battery does not fit the compartment easily, it means that
either polarity was reversed or the battery contacts are jammed.
To remove battery:
.
.
Slide the battery compartment cover down (Fig. 2)
Shake the rangefinder gently towards the open end of the
battery compartment
.
Pull out the battery
The unit is fully operational when battery voltage is higher than
6.2V. A ‘LOW BATTERY’ warning is displayed when battery
voltage falls below 6.5V.
Ni-MH rechargeable batteries capable to sustain current drain up
to 250 mA can be used to power the unit.
Note: Non-magnetic batteries should be used for peak compass
performance. If a non-magnetic battery is not used, you may
need to calibrate the unit after changing the battery (see Compass
calibration below for more details).

Measuring procedure
When the unit is powered off the LCD will appear blank. To
activate the unit press and hold A button (Fig. 1) for half a
second. The word ‘READY’ will appear on the display to
indicate the unit is powered on.
Pressing the A button (Fig. 1) in Ready to Measure mode will
initiate measurement. The result of the measurement is displayed
in a form that depends on the measurement parameters (see Setup
Mode).
If a measurement is unsuccessful for any reason, four dashes (‘---
-‘) will be displayed on the LCD. For successful measurement
the target must be at least 10 m away.
If more than one parameter is chosen to measure, e.g. distance
and elevation, the results will replace each other on the display
every second.
Maximum distance
Though maximum measurement distance depends on target
reflectivity, weather conditions and other conditions, for most
relatively large targets the unit will provide accurate ranging for
up to 2,200 meters. The indicated measurement range (2,200
meters) is proven to a NATO standard target with the following
characteristics: 2.3x2.3 meters, albedo 0.3, visibility >20km.
Target reflectivity depends on its color, surface finish, size,
shape, position in relation to the laser beam and other factors.
Bright target colors are more reflective than darks. A polished
11
Download from Www.Somanuals.com. All Manuals Search And Download.
surface is more reflective than a rough one. Larger targets reflect
better than small ones. Ranging a target perpendicular to the laser
beam provides better results than the one positioned under a
sharp angle to the beam.
Weather conditions that influence air transparency (rain, fog,
snow, mist) reduce maximum range. Bright sunny days will
reduce performance as well, as IR sun radiation may interfere
with reflected laser impulses.
While the unit will measure through many glass types, measuring
through glass may reduce accuracy.
Natural hand tremor decreases the accuracy of long distance
ranging. Use of a tripod is highly recommended.
Target selection logic
On its way towards the target the laser beam may reflect off
various objects in the atmosphere, thus decreasing ranging
accuracy. The smaller, the farther, and the less reflective is the
target, the higher is the possibility of obtaining an incorrect
measurement.
To improve accuracy the unit has a built-in target selection logic,
which allows choosing which target to range: the nearest (‘first’),
the farthest (‘last’), or the most reflective (‘auto’).
This mechanism helps selecting the target when ranging from
behind bushes, wires, through falling snow, or in similar
conditions. Similarly it enables ranging a target in front of a
bigger object, such as a wire in front of the wall.

Note: Even with target selection logic the unit may not always be
able to range the desired target as its reflectivity may be too low
to produce enough laser beam reflections for statistically reliable
calculation. A warning will be displayed if the result is not
statistically reliable. See more about target reflectivity in
Additional display information.

1 – Accuracy of correction will depend on accuracy of
installation against the target. It must be exactly as specified. The
numbers shown on the display reflect the correction.

not considered high reflective in this case).
3 – The unit shall be well levelled with deviation from 0 not
more than ±0.75 degrees. Horizontal direction shall be to

Magnetic North (not True North). If the unit detects large
installation errors (unit is not well levelled or not aimed to the
North), then LCD will show result “444” and “99”, which means
that correction was not performed due to incorrect setup.
Compass calibration
If the System was exposed to a strong magnetic field or was not
in use for a long time, the compass accuracy may diminish.
To return the compass into working condition:
.
.
Select CALc from CAL menu
Keeping the unit horizontal, perform one full rotation around
vertical axis within half a minute and then one full rotation
around vertical axis with device upside down during half
a minute.
.
.
If one rotation does not restore calibration – perform two
rotations.
Normal compass function should now be restored.
Gating mode
In this mode gating function is activated. Here the minimal
distance to the target can be set. Any object closer than the
gating distance will be ignored.
To select Gating Mode:
.
Select GAtE from the mode menu
16
Download from Www.Somanuals.com. All Manuals Search And Download.
Minimal gating distance of 000 m will be initially set, further
pressing M button will increase gating distance by 100 m up to
2,100 m. When the desired distance is reached – select it by
pressing Action button.
OVER 100M – indicates that gating is active
To deactivate gating choose gating value zero or switch to the
default mode.
Note: The gating distance can only be increased. To exit the
gating selection cycle without setting any gating distance click
through full gating range with M button or hold M button for 2
seconds.
Gating feature helps measure remote targets in unfavourable
atmospheric and environmental conditions by eliminating
reflections from snowflakes, raindrops, industrial wires, tree
branches, etc. At the same time, if gating distance is set
incorrectly, you can remove the desirable object from
measurement range.
Individual Measurement and Scanning regimes
The unit can operate in two regimes: (1) Individual Measurement
and (2) Scanning. In Individual Measurement regime the unit
performs single measurement when A button is pressed shortly,
in Scanning regime the unit repeatedly measures and displays
results every second while A button is pressed.
Scanning or Individual Measurement regimes are available for
any selected mode of measurement. When two parameters are
17
Download from Www.Somanuals.com. All Manuals Search And Download.
measured in the Scanning mode, though both will be quickly
displayed, the second one may be difficult to register by eye.
Nevertheless all data is recorded and may be recalled (see Data
Recall mode for details.)
Data Recall mode
In Data Recall mode results of the last 10 measurements can be
displayed.
Measurement results are saved in on-board memory in sets
depending on the parameters set for measuring, for instance, if
only distance is measured - the set will consist of one number, if
distance and azimuth are measured – the set will consist of two
numbers.
To enter Data Recall mode select rEcfrom mode menu. First
measurement set number (display name: rEc 1) will start
flashing.
Pressing M button moves the unit along the list of measurement
set numbers and measurement results:
rEc 1, distance 1, azimuth 1 OR elevation 1,
rEc 2, distance 2, azimuth 2 OR elevation 1, …,
rEc 0, distance 0, azimuth 0 OR elevation 0.
Measurement sets are numbered in reverse order: first recalled
set is the result of the last measurement. If any parameter has not
been actually measured it will not be recalled.
18

Pressing A button at any moment within the list of recalled
results brings the unit to Ready to Measure mode.
Choosing cLr at the end of recalled data will erase the device
memory.
Additional display information
Additional indication is displayed in Ready to Measure mode:
Indicates that distance is displayed in yards or
Y or M
meters; elevation may or may not be measured
Indicates that only azimuth or elevation is
measured
°
KMH or
MPH
Indicated speed is displayed in either kilometres
per hour or miles per hour
Reliability of ranging depends on the number of impulses that
reflect from the target and reach the unit. The unit informs the
user:
TARGET REFLECTION LOW – ranging results have low
statistical reliability,
TARGET REFLECTION MED – ranging results have
medium statistical reliability,
TARGET REFLECTION HIGH – ranging results have
high statistical reliability.

6. BEST MEASURING TECHNIQUE
Laser range finder measures distance by catching laser beam
reflected from the target. Everything that improves reflection
increases the measurement reliability and maximum range.
1. Use tripod when ranging remote targets. The longer is the
distance, the greater is the beam shift due to hand tremor.
2. Aim at a bright smooth surface on the target that is the
closest to perpendicular to the laser beam. The closer to
perpendicular you get – the stronger will be the reflection.
3. The unit deploys sophisticated software that tries to
understand which target you are aiming at. However, due to
beam divergence several objects may produce a strong
reflection. To help the System recognise the target the
Target Selection Logic may be used. For example, if ranging
a wire in front of a building, selecting the “first” target will
produce a more reliable result. Alternatively, when aiming at
a chimney behind the trees, selecting “last” target will be
better. By default the System assumes “auto” target selection
choosing the object that produces most reflections at
maximum distance.
