Page 4: Before Use
Under no circumstances should you touch the integrated halogen bulbs or housings either during operation or directly after use. These bulbs produce significant heat and therefore there is a risk that the user could be severely burnt. So before handling the bulbs, you must check that they have cooled down.

Page 5: Storage
In most cases, if dust and dirt gets inside the optical unit of a microscope this can cause irreversible errors or damage. The best way to store accessories which consist of optical elements, such as, for example, eyepieces and objectives, is in a dry box with desiccant. OZL-45-BA-e-1510... -

Page 11: Operation And Functionality
As soon as the lefthand and righthand visual fields exactly overlap each other, this is the correct interpupillary distance. 5.3 Adjusting the magnification As the KERN OZL-45 series are stereo zoom microscopes, then you adjust the magnification using the two zoom adjustment wheels on the lefthand and righthand side of the microscope head. -

11. Then look through the left eyepiece with the left eye and use the lefthand dioptre adjustment ring to also adjust the optimum focus of the object. 12. In this way, the object being observed will be in focus at any zoom setting. OZL-45-BA-e-1510... -
Page 13: Adjusting The Stand
There is a metal ring which also ensures sufficient grip and which is fixed with a second screw (2) under the holder on the pillar. This metal ring proves to be particularly useful when the screw (1) on the holder is loosened, to swing the microscope head to the side. OZL-45-BA-e-1510... -
