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 tar -
get mark is as sharp as possible. The target mark
can be seen by pressing the release button (3). The
degree of compensation can be read off the "+" or
"–" scale (1b) on the rubber eyecup. Compensation
within the range of ±3.5 diopters is possible.
