DOCTER DOCTER®basic 3-12x56 - Manual (Page 13)

Focussing should in principal be effected at the highest magnification, as this is when,
due to the maximum resolution, the visual acuity can be judged best. A later change in
magnification does not change any previously adjusted focussing.
Accessories
One of the protective caps of the reticle adjustment is designed somewhat larger. It
serves to accommodate a spare battery format CR 2032 by means of a magnet.
Protective caps that are joined to each other are included in the supply to protect the
external parts of the optical systems.
As protection against sidelight, a rubber telescope light protection shield can be supplied
upon request. This shield at the same time guarantees the correct eye distance to the
eye piece and attenuates any recoil.
Care
The device should be protected against heavy soiling.
If necessary, the lens surfaces should be carefully cleaned with a soft, clean cloth or hair
brush.
Heavy soiling should be removed with distilled water to prevent any calcifications on the
surfaces. To remove greasy residues on the lenses, it is possible to use methylated spir-
its or a commercially available window cleaning agent.
We would like to point out that detaching parts of the rifle scope may lead to a loss of
water tightness and of the device's nitrogen filling.
In case of function-impairing damage, the device must be sent to an authorised service
workshop.
