Anything larger than the chain or cord may damage or prevent full operation of SmartShade. Before installing SmartShade, make sure there are no objects attached to your beaded chain or cord that may potentially jam the device.
Large Beaded Chain Connectors
If the connector on your plastic or metal beaded chain is larger than the chain, remove it by snapping the connector off at both ends. The connector provided in SmartShade's packaging is smaller and will not jam the device. All you need to do is replace your old connector with the provided connector by snapping the ends of your chain into it.
Large ball stoppers attached to your chain or cord are used to prevent it from your chain or cord from going too far into the headrail of your window shade. An attachment of this size will not pass through SmartShade and will prevent full operation. Since you will now be using SmartShade to set the position of your shades a ball stopper is no longer needed. Each ball stopper is unique, but most can be removed by snapping them off. Use pliers or other tools if needed.
Some window shades have cord tensioners installed at the end of the cord to prevent choking or strangling hazards. Since SmartShade acts as a cord tensioner and it is installed where a cord tensioner is usually placed, the old tensioner needs to be removed. Each cord tensioner may vary, but most can be simply unscrewed.
