Installation
DOCTERbasic rifle scopes exhibit a 30 mm centre tube diameter and are designed for
ring installation. The correct type of installation is selected based on the weapon model.
Your local gunsmith or specialist dealer will be happy to advice you with regard to the
optimum installation version.
Reticle adjustment
To adjust the reticle, the two protective caps (3) are unscrewed from the domes of the
reticle adjustment. By turning the handle elements located underneath, the hit point posi-
tion is changed. The top dome is used to change the height setting and the right-hand
dome to change the lateral setting.
Height adjustment (H) (4)
Turning the handle elements in direction of the arrow causes the hit point to be moved
upwards.
Lateral adjustment (R) (5)
Turning the handle elements in direction of the arrow causes the hit point to be moved to
the right.
The end of the adjustment range is noticeable because of the stoppers. To prevent an
accidental adjustment of the reticle and to guarantee water tightness, the protective caps
(3) must always be screwed back onto the two domes. Pay attention to the seat of the
sealing rings (6) when doing so.
To ensure that the "zeroed-in" zero position of the reticle can be quickly found when us-
ing different ammunitions or fillings, the scale disc (7) can be turned such after undoing
the cross-head screw (8) that both index marks (9) are facing each other.
The adjustment range for the hit point correction is well dimensioned. Should the scale
division nevertheless prove insufficient, we recommend you have the installation of the
rifle scope checked by a gunsmith.
Change of magnification
Depending on shot distance and light conditions, the suitable magnification can be easily
set by turning the variable ring (10).
To improve orientation, the most important magnification values are engraved on the
variable ring (10). At the same time, it is possible to set any intermediate magnification in
an infinitely variable manner at consistent image quality, visual acuity and absolutely
unchanged hit point position.
Setting the visual acuity
The visual acuity is set by turning the outer eyepiece ring (11). Possible eye deficiencies
have been compensated as soon as the reticle is perceived sharply during relaxed view-
ing.
An eye deficiency compensation of ± 2.5 dioptres can be effected.
