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-9-BA-e-1610... -

The image which is shown on the camera connected to the device can often have a different level of focus compared with the image on the eyepiece. In order to be able to bring both images into focus, the focus can be adjusted by those adapters when turning the attached black plastic ring. OZL-9-BA-e-1610... -
Page 18: Using Additional Accessories
You can fit these objectives by simply screwing them onto the existing standard objective with 1.0x magnification, which is already fixed to the microscope. When you are doing this, you must avoid touching the objective lenses with your fingers or leaving any dust between the standard objective and the auxiliary objective. OZL-9-BA-e-1610... -
