How do I remove the TV from the mount?

Loosen the locking screw 13, then lift the TV to unhook it from the arm. Ask for help as the assembly is heavy.

How do I manage cables with this mount?

Can I shift the TV laterally?

Is it safe to install this mount alone?

No, installation should be done by two people due to the weight. Follow all safety instructions. Ensure the wall can support 5 times the total weight of the TV and mount.
