OPERATING INSTRUCTIONS

Thank you for choosing the Leupold®Green Ring™RXB-IV™9x32mm digital laser range finding
binoculars. Before using the product, we recommend that you read this entire instruction manual.
This will ensure that you obtain the maximum benefit from its use and that you are aware of the
safety precautions that are important to remember when using it.
The Leupold RXB-IV 9x32mm range finding binoculars does employ
an EyeSafe FDA Class 1 and CE Class 3A laser in its operation.
Because of this, there are a few precautions that are important
to remember:
• Do not depress the POWER button while aiming at a human eye
or while looking into the optics from the objective side
• Do not leave the RXB-IV within the reach of small children
• Do not take the product apart as it has a self-protection device
in the electronic control module and may cause an electric shock
• Do not attempt to use any power source other than a CR123A
battery (or equivalent) — the RXB-IV is designed to prohibit
accessing any other external power supply
HOW THE RXB-IV WORKS
The RXB-IV is a top-quality 9x32mm binocular that incorporates
the additional benefit of a state-of-the-art laser range finder
capable of instantaneously and accurately measuring the distance
of a deer-sized animal from 10 yards to 700 yards (9 meters to
640 meters), an inanimate object from 10 yards to 800 yards
(9 meters to 732 meters), and a reflective target from 10 yards to
1,500 yards (9 meters to 1,372 meters). It emits a series of invisible,
infrared energy pulses that are reflected off the selected target
back to the optical unit. State-of-the-art circuitry and precision
computing circuits are used to calculate the distance instantaneously
by measuring the time it takes for each pulse to travel from the
RXB-IV to the object and back.

– TBR™, BOW or Compass readout –
Indicates one of the following:
• True Ballistic Range™to the target in
either yards (YD) or meters (M) based
on the ballistics group selected
• The direction of the target in a 360°
compass direction (0° representing North,
180° representing South, etc.)
– LOS readout indicates one of the following:
• The line-of-sight distance to the target in either yards (YD) or
meters (M); this does not account for the angle or ballistics
• Calibration and declination adjustment mode
BATTERY POWER STATUS INDICATOR
To determine your battery’s power level, look for the following
indicators:
FULL – A full battery bar indicates your battery is at or near
peak capacity.
HALF – A half-full bar indicates your battery has reached
half-capacity.
LOW – If the battery bar is empty, yet there is still data
displayed above the bar, the battery is low, and nearing
the end of its life.
NO POWER – If the battery bar is empty, and there is NO
data display shown above the bar, your battery is dead and
you must replace it. The battery status bar will flash and
the unit will shut down when no power remains.
CONTINUOUS MEASUREMENT OF A MOVING TARGET:
1. Follow the instructions for “Measuring distance…” as explained
previously.
2. Once the target has been measured, continue to hold
down the POWER button and follow the object as it moves.
3. The distance will automatically update as long as the POWER
button is continuously depressed.
4. This procedure can also be used to obtain the range of
multiple animals or objects; simply move the reticle from one
target to another while holding down the POWER button.
CLEARING THE LAST DISTANCE OBTAINED:
The last range reading taken, does not need to be cleared before
reading another object’s distance. For that reason, there is no reset
button. Simply aim at the new object using the reticle, depress the
POWER button and hold until the new range reading is displayed.
READING THE INTERNAL DISPLAY
The Organic Light Emitting Diode (OLED) designed into the optical
path can be manually switched between ranging modes, as measured
in meters (M) or yards (YD), or used to obtain distance readouts
while simultaneously viewing the target. (The RXB-IV can also
simply be used as a 9x binocular without activating the OLED.)
MEASURING DISTANCE WITH THE RXB-IV
MEASUREMENT OF DISTANCE WITH THE RXB-IV IS A VERY SIMPLE
OPERATION:
1. View the object of which the distance is to be determined
through the binocular.
2. Depress and hold the POWER button for more than one
(1) second to illuminate the display.
3. Align the reticle over the object being viewed.
4. Depress the POWER button again – this will cause the
laser to activate.
5. Read the distance as shown in the image field.

SETTING THE FOCUS
The RXB-IV uses an independent focus design; therefore each eyepiece
is focused independently of the other. To set the focus for the unit:
1. View an object at 200 or more yards (183 or more meters) away.
2. Cover the right objective lens.
3. Focus the image you see with your left eye using the left
eyepiece.
4. Uncover the right objective lens and cover the left objective lens.
5. Focus the image you see with your right eye using the right
eyepiece.
6. The RXB-IV is now focused clearly for most distances.

FUNCTION 1: TRUE BALLISTIC RANGE™
TBR calculates the equivalent horizontal
range (level fire range) from which
you can determine the correct aim
for the conditions. For example,
if you are shooting a .270 caliber,
130 grain (8.4 grams) bullet at 3,050 feet
(930 meters) per second up a 30° incline at 400 yards (366 meters),
direct line of sight, the TBR output will be 364 yards (333 meters).
State-of-the-art processing algorithms, developed by the same
engineers who developed Sierra Infinity©Exterior Ballistics Software
and who developed ballistics algorithms for many space vehicles
over the last 40 years, determine the True Ballistic Range with
incredible accuracy, eliminating potential errors that could cause
you to miscalculate your aiming point. The first step in correctly
using TBR is to Practice, Practice, Practice. Anytime you handle a
firearm or bow, you are ultimately responsible for your projectile.
The inclinometer output is shown in the lower portion of the display,
just right of the battery power status indicator.
For rifle users, adjustment or holdover
information can also be displayed. The
available settings are as follows: MOA
displays the minute of angle correction,
HOLD displays the inches or centimeters
to holdover the intended point of impact,
and BAS outputs the equivalent range to
use with Leupold’s Ballistics Aiming System™reticles or equivalent
horizontal range. TBR for rifle settings is effective to 800 yards
(732 meters) for most cartridges.
BAS (displayed as bAS) displays the equivalent
horizontal range. This is the range you
will want to use when shooting, rather
than the line of sight distance, which
may contain gross errors depending
upon the shot angle. Returns will be
displayed with equivalent horizontal range.
HOLD (displayed as HOLd) will display your
holdover for that target at that distance,
which is based upon the ballistics group
and sight-in distance you will choose in
a later mode. The upper digits display
holdover in inches if yards is the chosen
measurement output. Centimeters will
be displayed if meters is chosen for your
measurement output. Your hold will be
shown as “HI 999” or “LO 999”.
MOA Mode will show the minute of
angle adjustment for your target,
accounting for the True Ballistic Range.
The upper display will show MOA
adjustment as “UP 999” and “dn 999”.
SEVEN RIFLE BALLISTICS GROUPS
TBR includes ballistics settings for seven
cartridge groups specifically formulated
for the three functions of TBR, which
are displayed as A, B, C, AB, AC, BC,
and ABC. For example, if your cartridge
group is in Group A, the return in Function 1
will account for the shot angle and provide the proper distance for
holdover purposes (see Cartridge Table on page 4). You must choose
one of the seven groups, based on your cartridge and ballistics
information. TBR performance groups organize load performance in
a way that generally provides less than 2.5 inches (6.35 centimeters)
(1/2 minute of angle) of error in aiming out to 500 yards (457 meters).
The cartridge table shows a common assortment of factory loads
organized in their TBR performance groups. If you are shooting a
similar bullet weight and muzzle velocity that falls into the provided
selections, you can use that mode with full confidence.
Operation
When you initially push and hold the POWER button, for more
than one (1) second, the unit is ready for scanning. Pressing and
releasing the MODE button begins navigation of the menu.
To set or activate a function, you must advance the mode selector
by pressing the MODE button until that function is flashing. To
activate or deactivate that function, press the POWER button.
When a function is activated, the icon and the word “ON” will be
displayed. When a function is deactivated, the icon will disappear
and the word “OFF” will be displayed. Repeatedly pressing the
POWER button will repeatedly toggle that function ON/OFF.

Extreme Long Range Group Selection — If you intend to shoot
varmints or targets at ranges beyond 500 yards (457 meters), selecting
your group based on 800 yard (732 meters) performance will provide
a better performance match throughout this working range. Select
your group for extreme long-range shooting from the table below.
REMEMBER: Knowing your theoretical bullet path at long ranges
does not provide a license to take shots beyond ranges at which
you have practiced, particularly at game animals or where stray shots
could hit unintended targets. It is your responsibility to have intimate
familiarity with the performance of your firearm and take full
responsibility for the projectile. The RXB-IV digital laser range finding
binoculars may serve best as a tool for learning performance during
practice at a secure range so you are ready for that critical shot.

For hand loads or any other unique loads not shown in the above list, the
table on the next page provides a guideline for selecting the appropriate
TBR performance group. Check the ballistics performance of your load by
consulting your reloading manual, ballistics software, or by referring to
literature or Web sites provided by your cartridge manufacturer. You may
also visit the Leupold Web site at www.leupold.com for more assistance in
selecting your group. If you have your ballistics performance data, select your
performance group from the table on the next page based on the bullet
path at 500 yards (457 meters). Be sure not to confuse bullet path with bullet
drop. Bullet path will be related back to your sight-in range whereas bullet
drop relates only to the total drop of the bullet, regardless of sight-in range.

FUNCTION 2: BOW MODE
This mode, when activated, works with
TBR to provide the correct ballistics range
for arrows. Selecting the BOW mode
automatically deactivates the rifle mode.
The displayed range incorporates three
different ballistics groups (Group A, B, or
C) depending on the particular arrow drop.
You must choose one of the three groups, based on your bow and
arrow selection. Only one group can be selected at a time. Selecting
a new group deactivates all other groups. Most importantly, using
TBR effectively means to Practice, Practice, Practice. Anytime you
handle a bow, you are ultimately responsible for your projectile.
For best results, measure the drop of your arrow at 40 yards
(37 meters) when using your 20 yard (18 meter) aiming point.
1. Set up a small target point such as a two-inch (5.1 cm) circle of
paper high on a large, safe background, such as a stack of bales
backed by a solid backstop. Be sure to allow for three feet or
more of drop to avoid arrow damage.
2. Shoot 2 or 3 arrows at the target from 40 yards (37 meters),
using your 20 yard (18 meter) pin on the small target.
3. Measure the distance from the small target to the center
of the group of arrows.
4. Select your TBR bow group from the “Drop from 20 yard
(18 meter) pin at 40 yards (37 meters)” column in the
“BOW Group Data” chart shown above.
Initial velocity should only be used if an arrow speed chronograph
measurement has been obtained. Manufacturer’s published data
such as IBO speed is based on standard draw length and weight that
is likely to vary with your bow, therefore the actual performance
may not be the same.

through the binoculars, depress the MODE button and hold it
down for approximately 2 seconds. If you are changing from yards
to meters, a change in unit of measure will be indicated by the
illumination of the METER indicator while the YARD indicator is
turned off. If you are changing from meters to yards, the opposite
will occur.
NOTE: The RXB-IV will return to the last setting used each time
the unit is turned on.
FUNCTION 3: MATCH 13™RETICLE SYSTEM™
By selecting this mode, any one of 13 preloaded reticles can be
chosen as the primary aiming point for the RXB-IV digital laser range
finding binoculars. To select a reticle, press MODE repeatedly until
you approach the end of the menu options (just after selecting
meters or yards as the desired unit of output). Each successive time
MODE is pressed will change the reticle style. Press SET to select a
reticle. The reticle choices are as follows:
Bracket Square Duplex®: Brackets an elk torso
at 40 yards (37 meters) or a deer torso at 30
yards (27 meters). Provides easy aiming on 3D
targets and game for archers. Duplex provides
bold contrast for low light.
Duplex®:Familiar reticle to shooters from
riflescopes; draws eye to the center, easy to
see, does not cover the target in the center
where aiming is most critical.
Plus PointTM:Ideal for varmints and other small
targets. Small open center avoids coverage of
very small or distant targets.
Bracket Circle Duplex®:Provides bolder
aiming for low-light/low-contrast situations.
Brackets small game and 3D targets at 40 yards
(37 meters). Brackets a deer at 50 yards
(46 meters). Excellent for muzzleloaders.
Bracket SquareTM: Brackets an elk torso at
40 yards (37 meters) or a deer torso at 30
yards (27 meters). Provides easy aiming on 3D
targets and game for archers.
German #4: A favorite of European hunters.
Provides bold aiming and is free from
obstructions in the upper half of the field
of view.
Bracket CircleTM: Brackets small game 3D
targets and game at 40 yards (37 meters).
Brackets a deer at 50 yards (46 meters).
Great choice for muzzleloaders. Open compass
points draw the eye to the center.

FUNCTION 4: COMPASS MODE
The RXB-IV is equipped with a compass to allow for instantaneous
determination of direction as well as distance to an object.
ACTIVATING THE COMPASS MODE:
To use the compass feature of the RXB-IV, it is necessary to activate
compass mode by pressing MODE until the degree symbol is flashing,
then pressing POWER until the icon and the word “ON” is displayed.
CALIBRATING THE COMPASS:
Before using the compass for the first time at different places,
it is necessary to calibrate the RXB-IV in order to obtain a realistic
database and detect more accurate related azimuths.
To calibrate the compass for horizontal direction reading:
1. Press MODE until the degree symbol is blinking, and press
POWER to activate the compass mode.
2. Continue through the menu options selecting the unit of
measure and preferred reticle.
3. After selecting the type of reticle, “dEC” will flash. Press the
MODE button repeatedly until the proper declination angle is
displayed. The numbers will start at the current declination
angle (Ø if this is the first time setting this feature) ascending
until 30 is reached. After 30 has been reached, the next number
displayed will be -30, continuing to ascend each time the MODE
button is pressed. Press the POWER button to select the
appropriate declination setting.
4.
After the declination angle has been set by pressing POWER, “CAL”
will begin flashing, indicating it is time to calibrate the compass.
5.
To calibrate the compass, press POWER while “CAL” is flashing.
The number “1” will flash briefly, then display steadily. While “1”
is displayed steadily, rotate the RXB-IV one full revolution around
the Y-axis. Once this has been completed, press the MODE button
again, causing the number “2” to flash briefly, then display steadily.
While “2” is displayed steadily, rotate the RXB-IV one full revolution
around the Z-axis. Once this has been completed, press the MODE
button again and the RXB-IV has been properly calibrated.
The Leupold Green Ring RXB-IV is designed to be as easy to
operate as it is effective. However, there are times when minor
troubleshooting may be required.
UNIT DOES NOT TURN ON – OLED DOES NOT ILLUMINATE:
• Depress POWER button for more than one (1) second
• Check battery; replace if necessary
Troubleshooting
DISTANCE READING CANNOT BE OBTAINED:
• Make sure that the POWER button is being depressed
(as opposed to MODE button)
• Make sure that nothing, such as your hand or finger, is blocking
the objective lenses — as this could interfere with the emission
and reception of the laser pulses
• Make sure unit is held steadily while depressing the POWER button
• When using BOW mode, it is important to note that TBR returns
are limited to 60 yards (55 meters); returns greater than 60 yards
(55 meters) will be displayed in the LOS display
CHANGING BATTERY:
Changing the CR-123A battery is a simple operation on the RXB-IV.
The battery chamber cover is located on the underside of the unit

Care and Maintenance
surface, wipe the lenses very gently with a soft, clean cotton cloth
or quality, oil-free lens tissue. Use a small quantity of pure alcohol
(not denatured) to wipe stubborn smudges. Do not use velvet cloth
or ordinary tissue, as it may scratch the lens surface. Once the cloth
has been used for cleaning the body, it should not be used again
for the lens surface.
CLEANING THE MAIN BODY:
Clean the body surface with a soft, clean cloth and a dry cloth. Do not
use benzene, thinner, or other organic agents because they may cause
discoloration or rubber degeneration. Do not use alcohol for cleaning
the main body.
STORAGE:
It is always recommended that when the RXB-IV is not in use that it is
stored in the case provided.
Water condensation may occur on the exterior lens surface during
periods of high humidity. Therefore, store the RXB-IV in a cool, dry
place. After use on a rainy day or at night, thoroughly dry it at room
temperature, then store in a cool, dry place.
Do not leave the RXB-IV in a vehicle on a hot or sunny day, or near
heat-generating equipment, as this may damage or negatively affect it.
