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  
2
 
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  
 
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.  
12  
 
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.  
Operation and service modes

elevation in degrees, speed is set to km/h (not measured), cross  
reticle, most reflective (‘auto’) target selected, no gating.  
2 - this option is available only if Speed is selected from the Std  
menu.

Accuracy correction  
If the System produces any measurement errors that lie beyond  
unit specification, it may be an indication that unit requires  
14  
 
calibration similar to one conducted during production process.  
To perform the accuracy correction, select corr from the CAL  
menu.  
Perform correction according to required measurement  
parameters by pressing Action button, see table below:

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.  
2 – Target should not have high-reflective surface (white color is  
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  
15  
 
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  
 
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  
 
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.  
19  
 
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.  
20  
 
7. STORAGE AND MAINTENANCE  
The unit is a sophisticated precision optical instrument equipped  
with laser and electronics. Therefore, it should be handled with

The ranging mode does not work. The display shows results of  
the last measurement or is transparent.  
Wait for 16 seconds, and press the Action button again.  
Compass shows zero at any direction.  
Wait for 8 seconds, and press the Action button again. If this  
does not help, perform compass calibration.  
Black dots are visible on LCD.  
Liquid Crystal Display may have small black dots, scratches and  
other blemishes inherited from the manufacturing process. These  
flaws are strictly regulated by number, area and location and do  
not degrade the product's measurement capabilities.  
Range measurement cannot be obtained.  
Make sure that neither your hand nor finger is blocking  
objective lens, laser emitting lens or receiver lens.  
Hold the unit firmly (avoid hand tremor) while pressing the  
Action button.  
Check that the target is within measuring range of the device.
