* The measuring range depends on many factors. The longest measuring range is possible for bright,
large objects with a uniform structure, located perpendicular to the measuring device. Little sunshine
and an almost cloudless sky are the ideal weather conditions for using the binoculars.

Greater range Lower range
Target size: large small
Aiming angle: straight sharp
Structure of the object: uniform, e.g. wall a non-uniform, e.g. bushes
Insolation: slight very high (sharp sun)

USE
BATTERY INSERTION AND REMOVAL
The binoculars are powered by a CR2 3V battery. Before using
the binoculars, unscrew the battery compartment cover located
in the central focus adjustment knob by turning it counterclockwise.
If the battery is pre-installed, remove the plastic pull tab from
between the cap and the battery.
If there is no battery, insert it with the correct polarity (see the marking
on the battery compartment cover). Turn the battery cover clockwise.
At 20 °C the new battery is sucient for approx. 2,500 measurements.
However, depending on the conditions of use, e.g. in lower temperature
or in case of more frequent use of the continuous measurement (scan)
mode, the battery life can be significantly shorter. Be sure to check the
battery indicator on the display.
If the device is not used for a long time, the battery should be removed
to avoid damage caused by leakage. Please use only high-quality
batteries.

NECK STR AP ATTACHEMENT
Delta-T 9x45.HD.RF binoculars come with a neoprene neck strap.
Pass it through the lug of the binoculars and through one lug of the
rainguard (eyepiece lens protective cover).

USING THE BINOCULARS WITH AND WITHOUT YOUR GLASSES ON
Delta-T 9x45.HD.RF binoculars have adjustable eyecups.
Using the binoculars with your glasses on: Twist the eyecups down
by turning them clockwise until the eyecups lock in the lowest
position possible.
Using the binoculars without your glasses on: Twist the eyecups up
by turning them clockwise so that the eyecups lock in the highest
possible position.
Note: when storing and carrying the binoculars, twist the eyecups
down - it will protect them from accidental damage.

ADJUSTING THE INTERPUPILLARY DISTANCE
The proper distance between the two barrels of the binoculars should
be set so that when you look through the binoculars with both eyes
you will get a round image.
If the interpupillary distance is incorrect, you will not be able to obtain
a stereoscopic image and some dark spots and unexpectedly large
chromatic aberration may appear.
DIOPTER ADJUSTEMENT
If there are dierences in sharpness between the right and left eye,
adjust the focus first for the right eye and then for the left eye.
This is done as follows:
Close your left eye and turn on the display.
While looking at the display, adjust the display focus by adjusting
the diopter of the right eyepiece. Then, while looking through the
binoculars at the distant object, adjust the sharpness of the image
using the central focusing knob.
Close your right eye (or cover the right lens with your hand).
While looking at the object with your left eye, turn the diopter
adjustment knob located next to the left eyepiece and focus the
image so that you can see the object clearly with your left eye.
Diopter adjustement is done only once for a given observer.
Further focus adjustment is done only with the center knob.

LASER RANGEFINDER
Delta-T 9x45.RF.HD binoculars are equipped with a precise laser
rangefinder that allows for precise measurement of the distance
between the user and the target.
USING THE RANGEFINDER’S FUNCTIONALITY:
To access the binoculars’ menu, press the SET (3) button for approx.
2 seconds. Go to the next functionality, press SET (3), change a
parameter, press button 2 (4), confirm the selection by pressing SET (3).
While adjusting the settings, holding the SET (3) button for 2 seconds
or inactivity for 12 seconds will take the user back to the basic view.

MEASUREMENT MODES
The binoculars have three measurement modes: AUTO, SPORT,
HUNT.
SPORT: When measuring multiple targets, the distances of the
targets closest to the user are displayed. In this mode, objects
other than the target itself are not measured. In this mode,
measuring the distance takes about 3 seconds.
HUNT: When using continuous measurement (scan) mode and
measuring multiple targets, the values for the targets farthest
from the user are displayed.
CONTINUOUS MEASUREMENT (SCAN) MODE
In AUTO and HUNT modes, the user can also take measurements
in continuous (scan) mode. To do this, press and hold the button
No. 2 for approx. 3 seconds. The binoculars then switch to the
scanning mode and take continuous measurements. The continuous
measurement mode turns o when the No. 2 button is released.
Continuous distance measurement is helpful for small or moving
targets. Continuous (scan) mode is limited to 20s.

T. Angle measurement. This is the angle of the binoculars relative
to the observed object.
V. Vertical measurement. It is a measurement of the height of the
measured object.
Note: The height of the observed object is measured from the
position of the binoculars, not from the ground.
H. Horizontal measurement. This mode measures the equivalent
horizontal distance.
OFF. Disabling additional measurement parameters. After pressing
OFF the binoculars measure linear distance to observed object.
ADDITIONAL MEASUREMENTS
The binoculars have three additional functionalities. After selecting
the desired functionality, the value is displayed alternately with the
linear distance measurement.

DISPLAY BRIGHTNESS
To change the brightness of the display, select the DISPLAY
function. The binoculars have five display brightness levels.
The display is set to position 3 by default.
MOUNTING THE TRIPOD ADAPTER
Delta-T 9x45.HD.RF binoculars are equipped with a socket for attaching
a tripod adapter with a 1/4 inch thread. To mount the tripod adapter,
unscrew the mounting socket cover on the front of the device between
the objective lense barrels. Then screw in the thread of the tripod
adapter mounting.
MAINTENANCE
If you want to keep your binoculars in the best possible condition,
you should keep them clean. Dust is best blown out or removed
with a brush. Pay attention to any solid particles (sand grains and
similar) - they can scratch the surface when cleaning. Only after
removing sand and dust can the optical surfaces be wiped with a
soft microfiber cloth. It is also recommended to use special liquids
for cleaning optics.
Note: We do not recommend using paper for cleaning. Paper can
damage anti-reflective coatings, some types of paper contain
contaminants that can even scratch the lens surface.
The binoculars should be stored in a dry place and always with good
ventilation of the outer surfaces of the lenses.
