Battery door compatible with the QX Stand. Not all CHS Scanners are QX Stand-ready. To verify that your CHS 7Qi is QX Stand-ready, please confirm that the scanner came with a battery door (similar to the image) with the metal disk near the twist-lock. If your scanner has this battery door, your scanner is QX-Stand ready! If your scanner does NOT have this QX Stand battery door and it is a CHS 7Qi, the scanner needs to be factory updated and a new battery door installed. If your scanner does NOT have this QX Stand battery door and it is CHS model (7Ci or 7Mi)*, and you would like to use it on a QX Stand for docking and charging purposes only, add to cart. *These models do not support the "Grab & Go" feature. The CHS 7Qi & 7Xi with the QX Stand come with added intelligence allowing you to go from scanning by hand or scanning using the stand in seconds.
