6 Locate the case that holds the stylus that you want to install. After opening the case, use tweezers to gently 
lift the stylus holding ONLY THE SILVER MAGNETIC DISK PAD AT ITS BACK END.
7 Align the magnetic disk pad of the stylus with the magnetic disk pad on the stylus exchange tool.
8 Seat the stylus in the channel on the exchange tool. The stylus arm should extend out through the front 
channel on the exchange tool.
9 Rotate the thumbwheel on the left side of the stylus exchange tool counterclockwise to display the green 
circle and engage the magnet.
10 Place the stylus exchange tool underneath the sensor head on the DektakXT profiler. Holding the stylus 
exchange tool by the sides, align the alignment pins on its top with the outside of the front of the sensor 
head. Gently push up until the tool is flush with the bottom of the sensor head. The ridge at the back of the 
stylus exchange tool must roughly line up with the back of the sensor head.
