6: Applying the GSN
Lift the Net vertically out of the electrolyte bucket, waiting a moment for the
6
Net to drip excess electrolyte back into the container (Figure 6-6).
For the GSN 200 , hold the Net over a towel and gently touch the sensors
7
against the towel a few times to further remove excess electrolyte. For the
HCGSN, do not touch the sensors against the towel (the sponges in the
HCGSN are smaller and soak up less electrolyte).
Note: Do not squeeze or press the sponges to remove excess electrolyte, because the
sponges may become depleted of electrolyte. It is harmless for some dripping to occur, as
long as the Hypertronics connector remains dry.
WARNING!: To prevent subject cross-contamination, make sure that the towels
used by the subject and those used with the GSN are kept separate. Do not use the
same towel to dry the subject's face or hair, and then to pat the Net dry. Also do
not use the same towel for more than one subject.
Proper Position of Hands
Proper positioning of the hands is important because it enables you to stretch the
Geodesic Sensor Net over the subject's head without unduly straining the tension
structure and to remove your hands easily from the Net, once it is applied.
Hold the GSN draped over both hands and become acquainted with the Net's

orientation:
° Locate the front of the Net, which is identifiable by the face straps, including

also features red labels on the nasion and cardinal sensors, as shown in
