Use with and without glasses
If you are not wearing glasses, leave the rubber
eyecup (1a) folded up, as it comes (Figure A).
This position gives the correct distance between
the eye and the Leica Rangemaster CRF.
When viewing with glasses, fold down the rubber
eyecup (Figure B).

Diopter compensation
The diopter compensator allows you to adjust
the sharpness of the target mark to suit you
best. Simply target the Leica Rangemaster CRF
on some far away object and turn the rubber
eyecup (1a) until the target mark is as sharp as
possible. The target mark can be seen by press-
ing the release button (3). The degree of com-
pensation can be read off the "+" or "–" scale
(1b) on the rubber eyecup. Compensation within
the range of ±3.5 diopters is possible.
