Use With And Without Glasses; Dioptric Compensation - Leica Rangemaster CRF 1600 Instructions Manual

A

USE WITH AND WITHOUT GLASSES

Users who do not wear glasses can leave the rubber
eyecup (3) raised (Figure A, as supplied). This position
gives the correct distance between the LEICA RANGE-
MASTER CRF 1600 and the eye.
When using with glasses, the eyecup should
be pressed down (Figure B).

DIOPTRIC COMPENSATION

Dioptric compensation enables you to adjust the
sharpness of the target mark to the optimum value
for you. Simply aim the LEICA RANGEMASTER CRF
1600 at a distance object and adjust the target mark
until it has optimum sharpness by turning the eyecup
(3). The target mark appears when you press the main
button (2). You can read the set value on the "+" or
"-" scale (3b) on the eyecup.
Dioptric compensation is available for vision defects
of up to ±3.5 diopters.
