1. BRIEF DESCRIPTION
LRM 1200 / 1500 / 1500SPD Laser Rangefinder Monocular
(the unit) is an advanced laser range finder system that enables
instant distance and speed (1500SPD modification only)
measurement.
The unit complies with CFR 21, Part 1040.10.
An outstanding fully multi-coated optics coupled with an original
circuitry design creates a system that outperforms any other
product in its class and price range.
Principle of operation
The unit sends invisible, eye safe laser beam pulses to the target.
The pulses reflected from the target are captured and processed
by the digital circuitry. The time-of-flight delay between the sent
and received pulses allows calculating the distance to the target.

Key Features
Distance is displayed in meters or yards
Original digital circuitry allows ranging through most types
of glass, bushes and other obstacles
Three channel optical solution (optical, laser and receiver)
provides high accuracy
Two reticle shapes: -¦- or 
Target quality display indicator (1200 / 1500 modifications
only) assures that results are reliable
On-board memory keeps results of last 10 measurements,
that can be recalled to the LCD
The unit automatically turns off when no button is pressed
for 10 seconds

Changing battery
To install a battery:
Slide the battery compartment cover down (9, Fig. 2)
Install the battery observing polarity
Don’t apply superfluous strength while pushing the battery
inside the compartment.
Close the compartment cover
If the battery does not fit the compartment easily, it means that
polarity was reversed
To take a battery out:
Slide the battery compartment cover down (9, 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
7V. A ‘LOW BATTERY’ warning is displayed when battery
voltage falls below 7.2V.
Ni-MH rechargeable or other 9V batteries capable to sustain
current drain up to 150 mA could be used to power the System.

11
Measuring procedure
To start the measuring procedure, remove the lens cover. Look
through the eyepiece (1, Fig. 1, 2) and adjust the focus by its
rotating.
When the Rangefinder is off the LCD is blank. To activate it
press and hold A button (6, Fig. 1) for half a second. At start the
unit comes into Ready to Measure mode indicated by the word
‘READY’ on the display visible through eyepiece. You may
need to adjust the focus again so that both the display and distant
objects are seen sharp through the optical system.
Pressing A button (6, Fig. 1) in Ready to Measure mode initiates
measurement. The result of measurement is displayed in a form
that depends on the measurement parameters (see Setup Mode).
If measurement is unsuccessful four dashes (‘----‘) will be
displayed in the area (4, Fig. 3). For successful measurement the
target must be at least 20 m away.
The unit will switch off automatically after 10 seconds of
inactivity.
Maximum distance
Though maximum measurement distance depends on target
reflectivity, weather conditions and other conditions, for most
targets the unit will provide accurate ranging for up to 1200
(LRM 1200) or 1500 (LRM 1500 / 1500SPD) meters.

12
Target reflectivity depends on its color, surface finish, size,
shape, position in relation to the laser beam, etc. 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. Using of a tripod is recommended to measure distant
targets.
Mode selection
By pressing the Mode button (5, Fig.1), you can sequentially
scan the Modes. The Mode under selection is indicated on the
Display by flashing of the selectable feature. The "flashing"
feature can be selected by pressing the Action button (6, Fig.1).
The System operates in the setting Modes that are displayed as
follows (refer to Fig.3):
Y/M: units of measurement: yards or meters (3, Fig.3).

13
KMH/MPH: units of speed measurement: km/hour or
miles/hour (3, Fig.3) (LRM 1500SPD only).
Shape of the reticle: cross shape or rectangular shape (2, Fig.3).
rEC1: Data Recall mode. It returns results of the last 10
measurements on the display.
Measurement results are saved in on-board memory. When you
enter the Data Recall mode, 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, rEc 2, …, rEc 0.
If distance was not measured, it will not appear in the list.
Measurement sets are numbered in reverse order: first recalled
set is the result of the last measurement.
Pressing A button at any moment within the list of recalled
results (or pressing M button at the end of the list) brings the unit
to Ready to Measure mode.
Clr: clear data function: upon pressing the Action button (6)
(fig.1) the entire data from all previous measurements will be
erased.

14
Additional display information
Distance measuring procedure includes instant statistical
processing of the package of single measuring sessions. If there
is more than one measured target in the field of view, the
embedded software estimates the most probable one by
calculating the number of reflected pulses multiplied by the
target statistical weight. This mechanism allows automatic
mitigation of the influence of obstacles like rain, flakes, trees,
wires and so on.
Qualitative result of the statistical processing is presented on the
Display as a message TARGET REFLECTION (5, Fig 3).
There are three statistical qualifications of the reflected signal:
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.
The target reflection feature is not available in 1500SPD model.

6. STORAGE AND MAINTENANCE
The unit is a sophisticated precision optical instrument equipped
with laser and electronics. Therefore, it should be handled with
due care.
Keep away from direct sunlight.
Avoid impacts, jolts, dust, moisture, and sharp changes of
temperature.
Do not use the device at temperatures higher than 50oC
(122oF).
Prevent unit from direct sunlight
Do not touch optical surfaces. Doing so may damage the
anti-reflection coating.
Clean optical surfaces only with professional camera lens
cleaning supplies.
Clean the exterior of the unit with a soft clean cloth.
Keep away from heating appliances and central heating.
Remove the battery when storing the device for long time.
All repair works must be performed only by an authorized
service.
Prevent bright light from focussing through the eyepiece

16
7. TROUBLESHOOTING
The ranging does not work. The display is transparent.
Check the charge of the battery. Replace it if it is weak.
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.
