- Page 4 1 Before use 1.1 General notes You must open the packaging carefully, to make sure that none of the accessories in the packaging fall on the floor and get broken. In general, microscopes should always be handled carefully because they are sensitive precision instruments.
- Page 5 1.3 Storage You should ensure that the device is not exposed to direct sunlight, temperatures which are too high or too low, vibrations, dust or a high level of humidity. The ideal temperature range is between 0 and 40°C and a relative humidity of 85% should not be exceeded.

- Page 9 4 Assembly The assembly of the microscope stand together with the holder has to be carried out as follows: 1. Microscope stand base Place the stand with the attached pillar on an even and stable table surface. 2. Microscope arm Attach the arm to the pillar with help of the joint, which is already fitted to the arm.
- Page 10 5.3 Adjusting the magnification For the OSE 409 you can select only one magnification factor. The standard total magnification equals from the factor of the eyepieces (10x) and the factor from the objective (1x). Thus it is always 10x.
- Page 11 5.4 Dioptre compensation and focussing A special feature of stereo microscopes is that they are fitted with an optical unit which has a relatively large range. In order to be able get the most benefit from this feature, each user must synchronise the focussing mechanisms for themselves. The steps to do this are described in the following section.
- Page 12 5.5 Adjusting the stand Torque of the focus wheels You can adjust the torque of the focus wheels by turning the ring which is fitted along the axis of the lefthand focus wheel. To do this you need a special wrench which is included with delivery. The ring has holes which the wrench can hook into, so that you can then turn it in the desired direction.
- Page 13 5.6 Using eye cups / High Eye Point eyepieces The eye cups supplied with the microscope can basically be used at all times, as they screen out intrusive light, which is reflected from light sources from the environment onto the eyepiece, and the result is better image quality. But primarily, if eyepieces with a high eye point (particularly suitable for those who wear glasses) are used, then it may also be useful for users who don’t wear glasses, to fit the eye cups to the eyepieces.
