Setup, Compatibility & Care
To install the eyepiece, simply align the bayonet mount on the HR3 with the corresponding slot on your Opticron scope body, insert, and rotate until it clicks securely into place. If you are using an IS series scope, you must first attach the specific compatible adapter before connecting the HR3.
For care, always keep the protective caps on the eyepiece when not in use to prevent scratches. If the lenses collect dust or residue, use a lens cleaning pen or a soft, microfiber cloth. Avoid using harsh solvents. Store the eyepiece in a cool, dry place to prevent internal fogging or mold growth. If the twist-up eyecup becomes stiff over time, gently clean around the threads with a dry cloth.
