General Information
The DOCTER®
reflex sights are excellent aiming optics devices of up-to-date design.
With their small size and low weight as well as their compact shape without using a
tube, they offer various possibilities of use on hunting and sport.
The solid workmanship, the high optical performance, an attractive design and the
functional reliability even in case of extreme weather conditions will cause your
DOCTERsight C to become indispensable.
Delivery Extent
The delivery extent includes:
2 M3x8 countersunk socket screws (TORX) to fasten to the mounting plate
1 T10 hexagon wrench key (TORX) to tighten the fastening screws
1 screwdriver (0.4 x 2.0)
1 scale wheel with device-specific scale disc
2 soft covers
1 coin cell (3 V, CR 2032)
Operating instructions
Let a gunsmith do the DOCTERsight C mounting and the shooting adjustment
of the gun. Put on the cap not before the mounting has been completed.
Putting into Operation
For the power supply, one CR 2032 lithium battery (3 V) is needed. Any other kind of
power supply is excluded.
Insert the battery into the battery compartment at the bottom of the enclosure such
that the labeling of the battery with the marking of the plus pole is visible. A danger to
damage the electronics due to an incorrect insertion does not exist. For a better
contact, a magnet causes the battery to be pulled toward the gold-plated contact
plate on the circuit board. The contact area is to be kept clean (cleaning using spirit).
Replacing the battery
To replace the battery, the DOCTERsight C is to be removed from the mounting
plate. The battery compartment is located at the bottom of the device. The exhausted
battery is taken out by putting the wrench key (or the screwdriver) onto the notch
located at the right bottom side. When the battery has been replaced, the sight is put
back onto the mounting plate and is fastened with the 2 countersunk screws. Due to
the precision positioning pins, a new shooting adjustment is not required.
Switching on/off
A mechanical on/off switch is not present. To switch off the electronics, the soft cover
is put on. The putting-on effects a switching-off of the electronics.
Mounting
Due to multitude of different adapter plates, the DOCTERsight can be mounted to
nearly all gun types without any problems. Your gunsmith will choose a convenient
mounting according to your requirement and to the gun type.
Independently of the used mounting type, the upper side of the adapter plate has 4
precision positioning pins.
Put the DOCTERsight onto the mounting plate where you have to consider the
fastening threads and the positioning pins. Then, fasten the device using the
delivered countersunk screws.
The combination of screw fastening and precision positioning pins prevents the hit
point position from shifting during the use.
Shooting Adjustment
Ex factory, the optical system of the DOCTERsight III is parallax-freely adjusted to a
distance of 40 m. You have to choose a shooting adjustment distance that meets
your requirements to the DOCTERsight III.
The DOCTERsight C has an elevation adjustment element (1) and a windage
adjustment element (2) that are separate from each other. These elements are
arranged at the top or at the right side of the device and are marked with rotation
direction arrows.
You will make the adjustment through of the slotted screws using the delivered scale
wheel and the delivered screwdriver (0.4 x 2.0).
Attention: Prior to each adjustment, the locking screws (3) have to be
loosened.
The elevation adjustment and the windage adjustment can be made independently of
each other. The available adjusting range allows the compensation of inaccuracies
on mounting as well as a ballistics correction. The windage adjustment has end stops
in both directions.
In case of the elevation adjustment, there has to be considered that the end stop in
downward direction is present in the mounted state only.
Please consider that the adjustments are clamped if there has been screwed up to
the end stop in the respective different adjusting direction.
Elevation and windage adjustment
To avoid the adjustment mechanism from being damaged, loosen the locking (3) of
the adjustment mechanism before doing any elevation and/or windage adjustment.
For that purpose, cause the two clamping screws at the rear of the DOCTERsight to
be moved back a quarter turn from the end stop (anticlockwise). To do that, use the
delivered screwdriver (0.4 x 2.0). The adjustment must be actuated without any
problems.
Adjusting the hit point position
To adjust the hit point position, a scale disc is included in the delivery extent. Push
the scale disc onto the delivered screwdriver where the scale has to be directed
toward the handle.
Now, cause the screwdriver to be set to the elevation adjustment (1) or to the
windage adjustment (2). According to the rotation sense shown on the enclosure and
on the scale wheel, you will get an aimed elevation or windage adjustment of the hit
point.
To read the division, use the markings (4) beside the adjustment elements or a
distinctive enclosure edge.
If you determine a deviation from the target point (light dot) to the hit point after the
first shoot, you can correct it as follows:
Hit point below the target point (gun shoots too deep):
Turn the adjustment screw in the Up direction.
Hit point above the target point (gun shoots too high):
Turn the adjustment screw in the Down direction.
Hit point to the left of the target point (gun shoots too far left):
Turn the adjustment screw in the R (Right) direction.
Hit point to the right of the target point (gun shoots too far right):
Turn the adjustment screw in the L (Left) direction.
One scale division corresponds to a shift of 3 cm at 100 m or to 1 angular minute. In
case of other shooting adjustment distances, the adjustment value changes
proportionally to the distance. For example:
1,5 cm at 50 m or 3 mm at 10 m
Brightness Control of Light Dot
Using an integrated control electronics, the different lighting conditions in the practical
use are considered. The light dot intensity is automatically adapted according to the
environmental brightness in target direction. The measurement is analog to the
sensitivity of the human eye. When the sensor at the front side of the sight is
covered, a visible brightness reduction of the light dot occurs. Therefore, the sensor
must not be covered by gun parts.
Maintenance and Care
To clean the optics, use glasses cleaning clothes. Before doing that, the optics
surfaces should be carefully cleaned using a soft and clean cloth or a hair brush
where no chemical solvents are to be applied.
Heavy dirt should be removed using distillated water. Otherwise, furrings can occur
on the surfaces.
In case of possibly function-affecting damages, the device has to be sent to an
authorized service workshop.
Hints
Due to their specific construction, DOCTER red-dot reflex sights do not have a
diopter compensation unit or other function units that compensate for the visual
defect of the human eye.
Thus, all individual visual defects of the respective shooter have a direct effect on the
contour of the perceived light dot.
Seeming ovality, sickle-shaped distortion, “star clusters” or a “frayed” contour of the
dot do not mean a defective device, but rather and exclusively mean a physiological
change of the eye (astigmatism).Then, it is recommended to use corrective glasses
or to have the eyes checked by an ophthalmologist.
Warranty
We grant a warranty of two years in the following extent:
1. In the warranty time, complaints that are based on material and processing

description of the present complaint is to be sent to the responsible DOCTER
agency, at your own expense.
3. Claims for warranty performances do not exist in case of improper usage,
