Remove the battery before storing the microscope for an extended period Using Method : Place the base of the microscope flush against a flat viewing surface Ensure the LED lighting is switched on Start focusing on the lowest magnification setting Once you have a clear view of your subject, increase the magnification to your desired level ( you may need to slightly adjust the focus again slightly ) A note on using the MicroBrite Plus in the field: Due to high magnification, the focal distance of the MicroBrite Plus is very short (maximum of 2mm past the acrylic base). It is not possible to focus on subjects beyond this focal distance. Looking at larger, three dimensional objects or objects that are not on a flat surface takes practice and a steady hand, especially since small movements are exaggerated with higher magnification. This is why we recommend viewing flatter objects on a flat surface, especially when first using this microscope.
