Lunar Blinds & Flyscreens

The tension clips sit on the cassette's left-hand side - flyscreen adjustment above, sunscreen below. Push a screwdriver into a clip, press gently inward, then twist it clockwise a turn or two to add tension, or anti-clockwise to slacken it off. Release the inward pressure slowly so it re-engages with its internal ratchet.

Recheck and repeat as needed until both crossbars settle back at the top by themselves. Avoid overtightening.
