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

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.

13
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

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

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
