Page 9: Operation
PM220 Series Operation Setting Up 1. Once you have placed your sample on the table or base below the objective, center the sample as best as possible. A slide is neither needed nor required for a stereo microscope, although they can be used if desired. If using a slide, use the stage clips to hold it in place. -
Page 10: Using The Trinocular Port
Operation Using the Trinocular Port The AmScope PM220 model is uniquely designed so that you can view the image through the eyepieces and the trinocular port without removing the camera or using your eyepiece. This feature allows the images through the microscope’s eyepieces, and those displayed on your computer screen or television be viewed at the same time (although unless using 20x eyepieces to match your camera, the image may differ in magnification). -

Doing so will void your warranty unless by advisement of one of our technicians to do so. - After use, cover the microscope with the provided dust cover. - Keep your AmScope microscope in a dry, clean location in order to prevent rust or other damages. -
