Range of Applications: The HEINE DELTA 20® is designed solely for surface examination. General Safety: To avoid dazzle from the intense, white, light emitting diodes (LED’s), do not look directly into the light source. Safety in use: Use only the HEINE photo adaptor and adaptor recommended by HEINE for photo-documentation ( ➛ Digital Photography). Electrical and mechanical compatibility of the HEINE DELTA 20® can be assured only when used in conjunction with 2.5V and 3.5V HEINE battery or rechargeable handles with HEINE AV or TL-connectors. If you use a digital camera, store your pictures first on the removable flash card and transfer the photographic images by connecting the flash card to the PC. A electrical conducting connection between camera, PC and a mains power source is not permissible. Use only with the HEINE contact plate (1) fitted. We can only guarantee the function of the instrument if it is used with a HEINE power source and HEINE spare parts.

Connect the HEINE DELTA 20® to the handle. Increased mobility and ease of handling can be achieved by using the extension cord ( see accessories) which connects the instrument to the handle. ● Turn the HEINE DELTA 20® on, and place it gently so that the surface to be examined is in the center of the contact plate (1). ● The examiner’s eye should be as close to the eye-piece (3) as possible. Adjust the focus ring until a crisp, clearly- focused image is obtained. ● Use the HEINE DELTA 20® without the contact plate when examining an uneven surface. Tip: Once crisp, clear focus has been achieved by adjusting the Focus ring, make a note of the position of the Focus ring (3) in relation to the linear mark (4) or edge of the instrument housing. This will help you to find your ”personal“ position and facilitate quicker focusing the next time you use the HEINE DELTA 20®.

● Attach the SLR-photo adaptor to the digital camera. If necessary, take a photo of the general area. ● Now adjust the Focus ring (3), aligning it’s lower edge with the linear mark (4). This will position the camera for the highest-contrast images. The distance ring supplied with the instrument simplifies this procedure. ● To mount the photo adaptor (6) to the HEINE DELTA 20®: Slide the Connector Ring (7) of the photo adaptor with one hand in the direction of the camera and hold in this position. Now guide the DELTA 20 into the photo-adaptor with the free hand until it clicks into the notch of the DELTA 20 body (5). You can now release the Connector Ring (7), it will automatically provide a tight connection between the camera and the DELTA 20. ● Make sure that the DELTA 20 is securely connected and that it can be easily rotated inside the photo adaptor. You are now ready to start producing digital images. ● To detach the DELTA 20 from the photo adaptor slide the Connector Ring (7) on the photo adaptor in direction of the camera and pull the DELTA 20 out and away from the camera. ● Tip: We can only guarantee the performance of the HEINE DELTA® Dermatoscope with HEINE Photo adaptor when used with one of the following SLR digital cameras: (www.heinetech.com ➛ DELTA 20 ➛ Camera for DELTA 20) ● The resolution of a PC monitor is not high enough to display all the pixels of a modern digital camera. To get the highest resolution dermatoscopic image possible, you should increase the image size. ● The size of the field of view depends on the size of the image sensor in the camera. The field of view can vary from one digital camera to another. (www.heine.com ➛ DELTA 20 ➛ Camera for DELTA 20)
