Single Key Hole vs Double Key Hole

Our Display or Panel Computer units may have Single Key Hole, whilst others have Double Key Hole present in the
chassis sides. This is due to slight variation in initial production vs Mass Production throughout 2012/2013. During
early/mid 2013, all units will feature Double Key Hole. Further, TMB type brackets are EN60945 tested, while the BRD
type are not. It should also be noted that Single Key hole units does not support ceiling mount. Double Key Hole
supports ceiling mount of unit.
Single or Double Key Hole can be identified as follows:
