For your safety

● Never use the rifle scope to look towards the sun! This will cause
damage to your eyes! Please protect your rifle scope from un nec –
essary solar radiation.
● Please note the eye relief distance specified for a mounted rifle
● Repairs should only be carried out by authorized workshops
other wise there won’t be any warranty on the scope after the repair.

General Information

● Compact construction, use of high-quality sealing elements and
nitrogene filling makes KAHLES rifle scopes perfectly prepared for
all usual types of operations.
● To ensure perfect alignment of the scope to the rifle, please
entrust mounting of the scope to a competent gunsmith. The rifle
scope shall be mounted centrical. The screws of mounts shall in
no case be tightened stronger than max. 240 N/cm. The reticle has
been factory-set to the mechanical middle position.
● Prior to mounting you can check the correct position of the reticle.
To do this, unscrew the screw-on caps(3) of the elevation adjustment
turret and windage adjustment turret. Now turn the elevation
adjust ment turret(4) and windage adjustment turret(5) in direction
of the arrow until it reaches the stop. Then turn the elevation
adjustment turret(4) and the windage adjustment turret(5) back
again opposite direction of the arrow until it reaches the stop and
count the clicks at the same time. Halve the number of clicks and
you will have the exact middle position. Repeat this procedure for
the second turret.
● Thanks to the use of high-quality sealing elements and controlled
fabrication processes, our rifle scopes are watertight and gas-tight
to a pressure of 0.4 bar or a depth in water of 4.4 yds/4 m. Seal
integrity is guaranteed even when the screw-on cap(3) has been
removed. Nevertheless, careful handling is advised, especially
around the turrets. Please protect your rifle scope against strokes
and adverse exzternal influences.


Zeroing In

Kahles Helia

● If the point of impact of the bullet deviates from the aiming point,
this can be easily and precisely corrected by adjusting the ele –
vation turret(4) and the windage turret(5) of the scope. Regardless of
corrections, the middle point of the aiming mark always stays in the
middle of the field of view. To make adjustments, simply unscrew
the screw-on caps(3) of the elevation(4) and windage(5) turrets.
When the shot is low
● Turn the elevation turret(4) in
the direction of arrow.
When the shot is high
● Turn the elevation turret(4) in
the opposite direction of arrow.
When the shot is to the left
● Turn the windage turret(5) in
the direction of arrow.
When the shot is to the right
● Turn the windage turret(5) in
the opposite direction of arrow.
● The impact point correction per click can be taken from the
information printed on the elevation(4) or windage adjustment
turret(5) of your rifle scope.




● KAHLES rifle scopes have their reticules in the central position ex
works. Correction of point of impact does not affect the reticule
image – it always remains centered in the field of view.
● Expert mounting is the precondition for optimum coordination
between rifle and scope in order to achieve perfect accuracy.

Zero Point Adjustment

Kahles Helia

● Once you have aligned the scope to the rifle, you
can retain this basic setting.
● The scale for this is located on the index disc (4.1)
of the elevation(4)/windage adjustment turret(5).
1. Loosen the locking screw(6).
2. Turn the index disc until the zero point of the scale is aligned with
the index point on the scope.
3. Fix the locking screw(6). The zero point is fixed now.

● Turning the eyepiece can correct de –
fective vision. You get a perfectly sharp and
clear image without glasses. It is not
necessary to wear glasses within the total
range of dioptric adjustment from +2 to
–3,5 diopters (except astigmatism).

Changing Magnification
● By turning the magnification adjustment ring(2) you can steplessly
set the desired magnification. The mayor graduations in magnifi –
cation are marked on the magnification adjustment ring(2).

● If the magnification increases, then the reticle remains the same
size – the size of the image is increased but not the size of the
reticle. Even for large magnifications only a little of the target is
covered. The reticle can only be used for estimating the distance to
a limited extent.
● Your rifle scope is matched parallax-free for a target distance of
110 yards (100 m). This means that at a distance of 110 yards (100 m),
the image of the object and the image of the reticle are in a single
● Please take into consideration:
With shots at distances greater or less than 110 yards (100 m), take
care to position the eye carefully central to the scope. This will
prevent shifting of the impact point due to parallax errors.

Operation of the reticle Illumination

Kahles Helia

● First, set the intensity of the illuminated reticle
to the respective light conditions. To do this the
illumination turret(7) may be turned from zero
clockwise until a setting is achieved where the
reticle is just bright enough to be picked up by
the eye without glaring.
● The illumination automatically turns off if no brightness adjust –
ment has been carried out within a period of 4 hours.

● The illumination system recognizes in the ON Modus if the
riflescope is in a shooting position or not. An inclination detector
measures the different angles of the scope and transfers this
information to the illumination system.
● If the scope is in a horizontal shooting position between 0 and 45
degrees (up and down) the red dot is lightning. From 45 to 75
degrees there are 2 minutes before the illumination gets switched
off. If the inclination is more than 75 degrees the light gets switched
off immediately. In the canting angle it works in the same way: from
0 to 75 degrees the light is on and will be switched off if the angle
has more than 75 degrees.
● If the riflescope remains motionless for more than two minutes
the illumination will be switched off but remains always ready in the
stand by modus. With a short motion the light turns on again.
● When Battery gets weak it starts blinking 3 times every 6 seconds.
(remaining time: 2 hours)
● In order to deactivate the “automaticlight”function there is a new
feature added. This allows change of illumination mode in a simple
● Hold the scope/rifle in a horizontal position. Turn the scope/rifle
through 180 degrees. Now the rifle is on top and the scope below –
both are still in horizontal position.


● Turn the illumination turret(7) in a short movement until it stops.
Now the “automaticlight”modus is deactivated.
● What is the result? No more automatic shut off – except scope/
rifle remains motionless more than two minutes. All other functions
are the same as in the first modus. (eg. turn on/off, increase/
decrease of brightness level).
● How to return to the first modus again? Repeat the same
procedure again.


Changing the battery

Kahles Helia

Turn off the reticle illumination.
● Remove the battery cover(9) with a coin turning
it counter clockwise.
● Remove the old battery.
● When installing the new battery (type CR 2032) please make sure
that the side marked “+” is facing upwards.
● Replace the battery cover(9) and turn it clockwise.

Standard Accessory

● Protective caps help to keep eyepiece and objective clean.
● Lens cleaner.

Lens-Cleaning Cloth

● The special microfibre cloth can be used to clean even the most
sensitive glass surfaces. It is suitable for objective lens, eyepieces
and spectacles.

● Please keep the microfiber cloth clean as dirt particles can
damage the lens surface. If the cloth is dirty, it may be washed in
lukewarm soapy water and allowed to dry naturally.
● Please use it exclusively for cleaning lens surfaces.


● We have designed all elements and surfaces to require very
little care.


The OILPHOBIC non-stick outer surface coating makes it much
easier to clean objective lenses and eyepiece lenses, especially
of any dried-on mineral deposits (e.g. water marks from con –
densation), insect repellents and tree resin.
● To ensure the long-lasting optical brilliance of your rifle scope, you
should keep the glass surfaces free from dirt, oil and grease. When
cleaning the lenses, first remove larger particles with an optical lens
brush. For subsequent thorough cleaning, breathe lightly on the
lens and clean with the cleaning cloth.
● The metal parts are best cleaned with a soft, clean cloth.


● You should keep your rifle scope in a well-ventilated, dry, dark
● If the rifle scope is wet, it must be dried prior to storage.
