Get the connector by using the jammer to open the door behind the purple barrier. Use the connectors to get the hexahedron. Move one of the connectors on the red button, the other one place near the last door. Help yourself with the jammer.
Place the hexahedron on the fan. Then, on the hexahedron place the connector that is linked to the transmitter and to the other connector near the last door. Turn the fan with the button, when the connector will be on the right altitude the door will open as shown on the picture.
Three Little Connectors... and a Fan (red)
Demount the fan and place it on the red button. Use as little connectors as possible to open the red doors. Utilize the window shown on the picture. Get the jammer and hexahedron by opening almost all doors.
Transport the hexahedron near the fan with the help of jammer and connectors. Install the fan and place the connector on the red button. Place the hexahedron on the fan. Connector linked with every door place on the hexahedron so that you will still have the maximum amount of free devices. Open the remaining doors with the jammer and the connector.
Use the connector that is in the air to walk through further doors, take the jammer with yourself while holding the door with the jammer. Open the last door with the jammer and take the sigil.
Get the connector with the help of jammer, open the doors from afar. Place the connector on the red button and take the hexahedron. Place the hexahedron near the fence with the jammer. Jump on the cube, take the jammer and get it on to the other side.

Big Stairs, Little Stairs (red)
Demount the fan and install it in the proper place to get the hexahedron. Place the cube at the base of wooden stairs and take another hexahedron from their top. With the use of fan and hexahedrons get third cube. Place them creating two steps at the position with the second hexahedron. Now you will have four cubes.
On the fan near the main entrance place one of the hexahedrons with a connector linked to the transmitter and doors with the fifth hexahedron on the other side. Activate the fan from the upper shelf and add the second hexahedron to the construction so that the connector will be even higher.
When you will get all five hexahedrons, build the construction again from scratches and join the connector with the doors before the sigil. Gradually add hexahedrons from below until four cubes will be supporting the connector. When the connector will get to the right altitude, it will open the door.
