NOTICE
The M A1028-200, M A1028-250 and M A1028-300 ne focus will install in very much the same
way. See the installation instructions that are included with each accessory.
1. Ensure the lock ring is threaded down fully on the Multi Focal lens before installing the lens on the
microscope body.
2. Thread the Multi Focal lens into the microscope body in the direction of the arrow shown until the lens
stops.
3. The knob location can be positioned for user comfort. Back the lens out of the microscope body
(NO MORE THAN 1 FULL TURN) to position the knob shaft in the desired location (right side for right-
handed user or left side for left-handed user is recommended).
4. While holding the multi-focal lens body, turn the lock ring until it is tight against the bottom of the
microscope body. This prevents the multi-focal lens from rotating after installation.
5. Attach the knob by pushing it onto the shaft until fully seated.
