8 Position the stylus exchange tool beneath the sensor head (see Figure 3-19 ).
9 Holding the stylus exchange tool by its sides, align the alignment pins on its top with the outside of the front
of the sensor head (see
Figure 3-19 ). 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. The stylus tip should extend out through the front of the channel on the exchange tool.

10 Rotate the thumbscrew on the left side of the stylus exchange tool so that a green circle becomes visible
and the magnet is engaged. The magnet now pulls the stylus into the channel on the exchange tool (see

to the protective case in which the stylus was shipped (see Figure 3-15 ).
11 To remove the stylus from the stylus exchange tool:
a. Disengage the magnet on the exchange tool by rotating the thumb wheel in either direction so that a gray
circle replaces the green one.
