The Laser range finder monocular is a portable optoelectronic device combined a laser
range finder and a monocular in one. Its function includes:
1). Measure the distance of a stationary and slowly moving object within a certain range
and can, at the same time, observe the object with great clearness It possesses many
advantages, such as a high accuracy,short measuring time, low power consumption and
automatic shutoff for power saving etc.
2). The transmission power of this device is very small and no harm to users' eyes, any
target can be measured at random. It is compact, accurate in measure,light in weight,
small in volume, very easy to operate and carry about. One piece of CR2/3v battery is
used which can be bought and changed easily.
The laser range finder monocular can be widely used for travel, sightseeing, golf sports,
hunting, camping as well as for any measurement of outdoor projects. It is a very good
assistant to improve our outdoor life quality.

5.1 Adj u st Telescope
Turn the eyepiece of the monocular until the target becomes clear.

5.2 Start
The Laser Range Finder Monocular has two buttons , they are" Start" button ( ) and
"Mode" button.
Press" "button for about 1 second and the Laser Range Finder Monocular will start.
The LCD will display as follows Figure3. :
5.3 How to operate the Laser Range Finder
The Laser Range Finder Monocular has two
"Mode", they Are" Range Mode" (default) and
"Speed Mode". Shortly press the"Mode" button
and they can be shifted one another. When"
Range Mode" is chosen,"Range"character will
appear on the top of the LCD, Shortly press
the" "button and the distance data will be
displayed on the bottom of the LCD
immediately.
If holding press the" "button, Scan measurement of distance start, The new measured

data will be displayed on the bottom of the LCD cease-less . After release the" "button,
Scan will stop and the LCD will return initiative state.
The laser indicator will blink when laser is transmitting.
In measuring the distance , If the reflection of target is too weak ,The LCD will display "-
- - -". If the measurement of distance succeed, "Quality ＞＞＞＞＞＞ "
will appear on the bottom of the LCD, The more numbers of "
＞
", meaning stronger
reflection.
Six grades in all are set for the quality of reflection. In measuring the distance , the LCD
will display as follows Figure 4. :

5. 4 How to shift unit "M" , "Y" - Meaning range unit , "M"means meter , "Y" means
yard.During the distance measurement period, you can change the measurement unit just
by long pressing the"Mode" button and it can be shifted between "M" and "Y".
5. 5 Automatic shut - off

If the device doesn`t work over 20 seconds, it will shut off automatically .
5. 6 Low battery indication
When" " appears , mean s the battery is low power and needs to be changed.

7 .1 The measuring distance of this laser range finder monocular has something to do with
the target's character, transmitting beams with the angle of the target's surface and the
weather visibility. In general, if the surface of the target is smooth, bright and large, the
beams are upright to the surface of the target and the weather is clear, the longer distance
can be measured, whereas the shorter distance will be made by the device.
7 .2 When " " (low battery indication) appears, battery should be changed in time,
otherwise the measuring errors will be increased. If the device is not used for a long time,
it's better to take out the battery from the housing.
7 .3 Never touch the surface of the lens so as to prevent the coating from damages during

the course of operation.
7 .4 This device has been accurately aligned and adjusted with high precise equipments.
Never disassemble it at random.
7 .5 If the external lens is stained, please clean it with the lens cloth attached to the device.
Don't use other things so as to prevent the coating from damages.
7 .6 Collision or high pressure should be avoided when carrying about or operating, keep
it away from the fire and prevent corrosion as well.
7 .7 Keep the device at a dry, cool and airy place and avoid dust, direct sunshine and
extreme change of temperature.
7 .8 If the device meets with a problem, send it to a professional department, never
disassemble it by yourselves.

CLEANING
Gently blow away any dust or debris on the lenses (or use a soft lens brush). To remove
dirt or fingerprints, clean
with a soft cotton cloth, rubbing in a circular motion. Use of a coarse cloth or unnecessary
rubbing may scratch the
lens surface and eventually cause permanent damage. For a more thorough cleaning,
photographic lens tissue and
photographic-type lens cleaning fluid or isopropyl alcohol may be used. Always apply the
fluid to the cleaning cloth
—never directly on the lens.
