Infasecure restraints use a model code beginning with the letters 'CS' (stands for 'Car Seat', clever huh?) followed by either 2 or 4 digits.
There are a couple of ways to find out basic or even detailed info on which model you have from the restraint.
1. Check the instruction booklet - on the front cover of the instruction booklet it will tell you the model series number for your restraint
2. On the side of the restraint - On both sides of the Car Restraint there are black instruction stickers. On both of these, in the top left corner it will tell you the model code. (Sometimes these labels may be partially hidden by the covers)
3. On the Barcode - for newer models the barcode label states the model code and name of restraint that you have. This is normally on the very back of the restraint for the majority of restraints.
