A: Think of regular blinds - they have a cord that you raise and lower to open and close the blinds. On these doors there's a sliding lever that runs the length of the window. Think of this lever being attached to the string that opens and closes the blinds. Just slide the lever down to pull the string and open the blinds. Raise the slider to close the blinds.
A: There is a tab that runs along side of the glass. Either lift up tab to close the blind or push down to open .
A: There is a sliding lever inside the door. It open and closes the blinds, and also slides the complete blind to the top of the door for a clear view out the glass, unobstructed by the open blinds. Remember, the blind system is encased in glass, so you can't physically touch/dirty them.
