Caution: Leave enough slack in the cable to allow a full range of motion.
To avoid the potential to pinch cables it is important to follow the cable routing instructions in this manual. Failure to follow these instructions may result in equipment damage or personal injury.
Removing from the desk: Remove monitors then put pressure forward while loosening the bolt.
