Congratulations! You have purchased a Leupold® RX®-1600i TBR/W Series digital
laser rangefinder that has been designed by Leupold’s engineers and designers to
provide you with years of accurate performance in the field. Following are detailed
instructions regarding the proper use and employment of your RX-1600i Series
rangefinder. To ensure top performance for the life of the product, please read these
instructions before operating your RX -1600i TBR/W. This manual was written in order
to provide you with all the information needed to properly operate and obtain years
of beneficial use from the RX-1600i TBR/W Keep it in a safe place and refer to it as
needed.

Your new Leupold RX-1600i TBR/W digital laser rangefinder is a range-finding device
that incorporates advanced digital electronics with ballistics algorithms. Digitally
eNhanced AccuracyTM (DNA®) engine incorporates additional signal processing
techniques to generate better ranging distance with more accurate rangefinding.
The RX-1600i TBR/W rangefinder features an incredibly bright OLED display,
inclinometer, Last Target Mode and True Ballistic Range/Wind (TBR/W) functionality.
TBR/W algorithms were developed by the same engineers who developed Sierra
Infinity® Exterior Ballistics Software and who helped develop navigation and
guidance systems for ICBMs and other missiles with far more demanding trajectory
requirements than a hunting bullet.

TBR/W is a marriage of laser ranging, an

inclinometer, and an advanced computerized ballistics program. The result is distance
measurements accurate to less than a yard, no matter the angle at which the laser is
fired.

Bullets and arrows travel in a ballistic arc, yet conventional rangefinders only
provide a linear or horizontal distance to your target. TBR/W delivers the ballistic
equivalent range to the target, accounting for the effects of inclines or declines on
the path of your bullet or arrow. For rifle shooters, the Leupold team has added to the
TBR/W functionality by adding wind hold calculations that will provide a fixed 10 MPH
full wind value. Other features that are provided for firearms are outputs that display
either MOA adjustments, or inches / centimeters / mils of holdover at that specific
distance. TBR/W eliminates any potentially significant error, and provides a precise
range for your aiming calculations.

TBR/W is matched to each of twenty-five firearm

ballistics groups, allowing use with most popular firearms.

HOW THE RX -1600i WORKS

The RX-1600i TBR/W is a top-quality 6x22mm monocular that incorporates the
additional benefit of a laser rangefinder that is capable of measuring the distance of
a deer-sized animal from 5 yards to 900 yards, an inanimate object from 5 yards to
1,200 yards, and a reflective target from 5 yards to 1,600 yards. 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 by measuring the time it takes for each pulse to travel from the
RX-1600

to the object and back.

The Leupold RX -1600i TBR/W 6x22mm rangefinder does employ an eye safe FDA

Class 1 laser in its operation. Outside of the United States, the IEC is the governing

body over laser products and has classified the RX-1600i TBR/W as Class 3R. Even

so, 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 RX-1600i TBR/W 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 CR2 battery
(or equivalent) — the RX -1600i TBR/W is designed to prohibit accessing any
other external power supply

SAFETY AND OPERATION PRECAUTIONS (cont.)

• Make certain that the laser beam does not strike on highly reflective
surfaces

• Read this instruction manual in its entirety before using this rangefinder.
If the product is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired

• Caution: Use of controls or adjustments or performance of procedures other
than those specified herein may result in hazardous radiation exposure

• When you see the display through the eyepiece, please be aware that the
product is active and emitting an invisible laser and the laser aperture
should not be pointed toward anyone

READING THE INTERNAL DISPLAY

The Organic Light Emitting Diode (OLED) display reflected into the optical path can
be manually switched between ranging modes, as measured in meters (M) or yards

(YD), or used to obtain distance while simultaneously viewing the target. (The RX

-1600i TBR/W can also simply be used as a 6x monocular without activating the
OLED.)

INTERNAL DISPLAY AS SEEN THROUGH THE RX-1600i TBR/W WHEN THE

POWER BUTTON IS DEPRESSED

– Indicates the distance to the target in
either yards or meters. RX-1600i TBR/W has the
additional capability of displaying the True Ballistic
Range to the target, or shot placement information.

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 – The battery is nearing the end of its life and should be replaced.
NO POWER – If the battery bar is empty, and there is no data displayed 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.

MEASURING DISTANCE WITH THE RX-1600

i TBR/W

Measurement of distance with the RX -160 0i TBR/W is a very simple operation:

1. View the object of interest through the monocular.

2. Depress the POWER button to power up the unit.

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.

8

CONTINUOUS MEASUREMENT OF A MOVING TARGET / SCAN MODE:

Follow the instructions for “Measuring distance…” as explained previously.

1. Once the target has been measured, continue to hold down the POWER button

and follow the object as it moves.

2. The distance will automatically update as long as the POWER button is

continuously depressed.

3. 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.

The ranging accuracy of the Leupold RX -1600i rangefinder is ± 0.5 yards/meters at
distances less than 125 yards/meters, while the accuracy beyond 125 yards/meters
is ± 2 yards. The maximum range of the unit depends on the reflectivity of the target
and atmospheric conditions.

Following is a reference table listing the ranges of the RX-1600i TBR/W under
different conditions:

Surface texture, color, size, and shape of the target all affect reflectivity, which in
turn affects the maximum range of the instrument. As a rule of thumb, brightly
colored targets are much more reflective than darker targets. Tan game coats are
more reflective (and thus provide a more solid reading) than a black roof. A shiny
surface is more reflective than a dull surface. Smaller targets are more difficult to
range than larger targets. Light conditions, haze, fog, rain, and other environmental
conditions can all affect ranging performance. Any factor which degrades air clarity
will reduce the maximum effective range. The sun generates infrared energy that can
degrade ranging performance in bright conditions or when ranging towards the sun.
