1 EYECUPS
1.1 Binoculars (HELIA & HELIA RF)
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 clock-wise until they stop.
1.2 HELIA 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.
3 DIOPTRIC CORRECTION
3.1 HELIA
Close the right eye and observe a chosen object with the
left eye only. Turn the focus knob until the object gets
sharp. Now close the left eye or cover the left objective
of the binocular and observe the same object with the
right eye only. If necessary turn the diopter ring until the
object gets sharp. Now your personal diopter adjustment
is set.
3.2 HELIA RF
1. Turn both dioptric correction wheels counter-clock wise
until they stop.
2. First look through the ocular with your right eye only
focusing the display. Turn the dioptric correction wheel
clockwise until the display is sharply focused. Now
look at an object through the right-hand eyepiece with
your right eye. Then focus on it using the focusing
wheel.
3. Now close your right eye (or cover the objective end
of the right binocular half) and look at the same object
only with your left eye. Turn the dioptric correction
