Attention:
To provide for a fast retrieval of the graticule’s zero position when using different ammunition
or fillings, the graduated disk (10) can be turned such after loosening the cross-drive screw
(9) that both index marks (11) face each other.
The adjustment range for correcting the hit point is sufficiently dimensioned. Should, however
the graduation not suffice, we recommend you have your rifle with the rifle scope checked by
your gunsmith.
Setting the visual acuity
The visual acuity is adjusted by turning the rear eyepiece focussing knurl (2). A marksman’s
possible eye defect is then compensated when graticule and target image stand out sharply.
Eye defect compensation of ±2.5 dioptres is possible.
Estimating distances
The free space between the transverse bars of the graticules 1, 4, 5, 7 and 9 corresponds to
a width of 70cm on a target distance of 100 m, approximately the length of a roebuck. You
can therefore estimate distances by means of the graticule.
Option: Rifle scopes with illuminated graticule
All control and functional elements of the graticule illumination system except the graticule
itself are placed in a third dome on the centre tube of the rifle scope, similar to the vertical
and lateral adjustment. The power supply is provided by a lithium battery CR2032. Using the
rotary controller (12) the graticule illumination system is turned on or off and the luminous
intensity can be adjusted according to the brightness outdoors and to the individual
requirements of the marksman. The graticule illumination system is turned off when the point
marking (14) on the rotary controller faces the one on the centre tube (13).
To replace the lithium battery, the cover of the rotary controller has to be unscrewed by
turning it to the left. The lithium battery situated under the cover (15) can now be replaced.
Then the cover can be screwed together again with the rotary controller (12).
Accessories
To protect the outer parts of the instrument, interconnected protecting caps are delivered.
As a protection against lateral light, a telescopic rubber shade can be delivered on request,
which simultaneously guarantees the correct eye distance to the eyepiece and absorbs a
possible recoil.
Maintenance
When carefully operated, DOCTER® rifle scopes have a virtually unlimited life.
Before cleaning, the outer lens surfaces should be freed from dust (by means of a lens brush
or air bulb). This way, dirt particles and dust are prevented from being rubbed into the
blooming coat and damaging it. Abstain from using chemical solvents for cleaning the outer
lens surfaces!
In case of possible damage causing malfunction, the instrument must be sent to an
authorized repair shop.
