Security Information
Pleasereadthesesafetyinstructionscarefullyand
follow them while using the product.
Under no circumstances should you use your
binoculars or other opt ical equipment to look
into the sun or bright or laser-based light sources.
This can lead to irreparable damage to the eye,
since the opt ics act as a magnifying glass.
Keep your binoculars out of the reach of children.
Also keep all attachments out of the reach of
children. In particular, small parts (danger of
swallowing) and the carrying strap (danger of
strangling) must be stored safely and carefully.
Please do not touch the metallic surfaces when
the product has been heated by the sun or is cold
as a result of exposure to cold atmospheres.
After use, always use the protective covers
supplied to avoid damage that may be caused by
the magnifying glass effect when exposed to
sunlight.

Theproductusesan invisible laserbeam formeasurement
and measures the time the laser beam takes to reach the
object and back.
Laser measurement depends on climatic and
environmental condit ions, as weil as the color, surface
texture, size and shape of the target to be measured.
Favorable conditions for range measurements are: Clear
visibility, low brightness (twilight), bright object color,
perpendicular angle and a homogeneous structure.
Range measurement is limited in conditions of haze/fog,
high brightness (sun), dark object color, sharp angle or
inhomogeneous structure (e.g. bush).
41

Attaching the carrying strap
lt is possible to attach the protective eyepiece cap to the
carrying strap.
Securing the lens cap
The lens cap can be secured to the strap connector with
the retaining cord.
Open the fastener and thread the upper part of the
retaining cord through the lanyard connection, then
secure the lens cap with the lower part of the cord.
42

Adjusting the eyecups
The rotating eyecups have three locking positions for
different applications. The detents allow the distance
between the eye and the eyepiece lens to be adjusted.
Thus,the distance viewing distance can be ergonomically
adjusted according to personal preference. A distinction
is made between use with and withoutglasses.
Use without glasses
When using without glasses, extend the eyecups as far as
they will go by turning them counterclockwise.
43

Use with glasses
lf you wear glasses while using the binoculars, retract the
eyecups as far as they will go by turning them clockwise.
Adjusting the correct interpupillary
distance
The binoculars have a mechanism to adjust the
interpup illary distance. The interpupillary distance is the
distance between the two pupils. The correct

lnserting the battery
Open the battery compartment by turning the battery
cover to the left {counter clockw ise) (e.g. with a 2-cent
coin) and insert the CR2 battery with the + pole first. See
also the markings on the rubber lining. Close the battery
compartment completely by turning it clockwise. Please
use only one CR 2 battery.
Battery warning
The CR2 battery is designed for approx. 4000 individual
measurements at 20 degrees Celsius. lf the charge on the
battery falls below 20% of its maximum capacity, the
battery symbol will flash 3 times when the instrument is
switched on. You can continue to use the device and
should replace the battery at the next opportunity.
46

Setting the Diopter compensation
for the target marker/reticle
Switch on the target marke re using the measurement
button and keep the button pressed. To adjust the focus
of the target marker and the display, turn the right diopter
compensation control (for the target marker) to the left (-)
orright (+).
Then use the central focus knob to carefully focus on the
image of the object in the right binocular tube. Use the
left diopter compensation control to focus the image in
the leftbinoculartubeonthesameobjectas before.You
can read off the set values on the (+) or (-) scale on the
back of the binoculars.
47

Distance measurement
The distance measurement mode is switched on by
pressing the measurement button once and remains in
standby for 15 seconds.
Press the measurement button again
within 15 seconds to start the
measurement. The distance is displayed.
To preserve battery life, the instrument
switches off automatically after 15
seconds of inactivity.
Single measurement
With theRANGEGUIDE 2800switchedon,usethetarget
marker to aim at the object tobe measured and press the
measurement button e briefly. The direct distance is
displayed in the first li ne for 1S seconds. The device then
switches off automatically.
lf the reflection from the object is not
sufficient for the measurement, the
following display appears:

Continuous measurement / scan mode
To switch on the scan mode, press and hold the
measurement buttone . As lang as you keep the button
pressed, the device will continuously measure the
distance to the target object and display the respective
distance to different objects.
lf you release the measurement butt one , the current
measured valuewillbe displayed fora further 15seconds
as for the single measurement. The device then
automatically switches to standby mode and then
switches off after 15 seconds.
The direct distance, horizontal distance and angle display
are updated up to 4 times per second.

Basic display functions
(Brightness, Meter/Yard, °C/° F, BEST / LAST)
To change the basic display options, switch the
instrument on by pressing the measurement button and
briefly (< 2 sec) press the menu button e within the
standby time of 15 seconds.
The brightness display will then flash LEV 4. You can
increase the brightness with the measurement button e
continuously up to level 9 and then again from 1 to 9.
Confirm the brightness adjustment with the Menu
button e and proceed to the Meter / Yard selection.
Now the unit M or Y tobe selected will flash. Select either
M or Y using the measurement butt one . Confirm by
pressing the menu button e to proceed to the
temperature selection.
Now the unit °C or °F to be selected will flash instead.
Press the measurement button e to advance and select
either °C or °F. Confirm by pressing the menu button e .
Finally, you will reach the BEST/LAST target selection.
Again, the BEST or LAST setting tobe selected will flash.
Please use the measurement butt one to select the
appropriate setting and confirm using the menu button e .
Once you have completed these 4 options, you have
configured your RANGE GUIDE2800.Adjustmentsshould
then only be made to the brightness in the basic settings.
However, you can change the 4 options selected here at
any time by following the procedure described above
again. For details on the settings, see the following
pages.

Display brightness setting
The RANGEGUIDE 2800 has 9 brightness levels for use at
ambient light levels from dusk (e.g. level 1, 2, 3) to bright
sunshine (level 7, 8 or 9).
The default sett ing is level 4 (LEV 4).
Sw itch on the instrument using the
measurement buttone and select the
display brightness suitab le for the
conditions .
Level 1 (darkest level) is ideal for extreme
twilight and may not be visible during the
day. Simply use the measurement
buttone to select a brighter setting that
is easy for you to read.
Distance Unit setting
The RANGEGUIDE 2800 is designed for
worldwide use. Therefore, you can
choose for the direct distance and
horizontal distance measurements to be
displayed in either meters (M) or yards
(Y).

Temperature unit setting
In addition to the direct distance in line 1,
the temperature in line 2 can also be
displayed in degrees Celsius or degrees
Fahrenheit.
Target selection behavior setting
The RANGEGUIDE 2800 offers two
operating modes : BEST for the strongest
target (best target) and LAST for the
furthest target (last target).
The BEST mode is the default and displays the object
with the strongest signal. This mode is recommended for
most applications.
The LAST mode displays the furthest distance when
scanning different objects. This mode is useful for
detecting and measuring a specific target behind a group
ofobjectssuchasbushes ortrees. (Here, themost distant
signal is preferred and strenger, closer signals are
suppressed).
