1 EYECUPS
1.1 Binoculars
KAHLES binoculars are equipped with
individual twist-in eye cups. Persons without
glasses can choose four different positions
(depending on the model). Eye
glasses
wearers, who wear eye glasses when
looking trough the binoculars, turn both eye
cups clockwise until they stop.
1.2 Rangefinder (RF-M)
The same applies to the monocular rangefinder. Adjustment
according to whether you wear glasses or not. Eyeglass
wearers flip the rubber eyecup over. For observers without
glasses or with contact lenses the rubber eyecup has to be
folded-up.
2 ADJUSTMENT OF INTERPUPILLARY
DISTANCE
To see a single circular image, you have to adjust the
halves of the binoculars to your interpupillary distance:
• Look through the binoculars eyepieces with both eyes.
• Turn the binocular halves around the central axis until
you don’t see any disturbing shadows and a single
circular field of view is visible.
