  • Page 4 General Warning Risk of blindness Never use this device to look directly at the sun or in the direct proximity of the sun. Doing so may result in a risk of blindness. • Do not place the device, particularly the lenses, in direct sunlight. The concentration of light could cause a fire.
  • Page 5 Adjusting the focus Look through your binoculars with your right eye closed. Now adjust the image for your left eye by turning the centre wheel (6) until it is sharp and clear. Close your left eye and adjust the image for your right eye by turning the dioptre ring (3) until it is also sharp and clear.
  • Page 6 TWILIGHT OUTPUT The twilight output number quantifies binocular visual performance and detail visibility in twilight condi- tions. Formula: √Lens diameter x magnification The result is evaluated purely mathematically and is only of interest when comparing differing types of binocular (e.g. 8x30, 7x50 and 10x50). The number calculated disregards binocular performance increase due to optical treatment, top-quality glass types and the like. See luminous intensity for more information. DIOPTRIC COMPENSATION In binoculars with centre wheel focusing, the right eyepiece can be adjusted.

  • Page 7: Field Of View

    FIELD OF VIEW This is understood to mean the visible image at a distance of 1,000 metres from the object being observed. This measurement is usually given in metres. If given as an angle, 1° = 17.5 m. An instrument with a field of vision over 120 m/1,000 m is called ‘large field’, and one with a field of vision over 140/1,000 m is ‘wide angle’. Wide angle instruments are particularly suitable for viewing moving ob- jects such as footballs or horses.
