5: Service and Maintenance
Caring for Your GSN
After each use, rinse, disinfect, rinse again, and dry the Net. Chapter 7, "Rinsing and
Disinfecting," provides step-by-step instructions.
Throughout these processes, protect the connector end of the Net from contact with
all liquids. It is helpful to place a plastic bag over the connector during this process.
Please post the Laminated Rinsing/Disinfecting Placard (page 117) provided by EGI
in a highly visible location.
Following are some important CAUTIONS that must be heeded to prevent
personal injury or equipment damage:
• Keep buckets separated. Do not confuse or swap the electrolyte and disinfectant
buckets.
• Don't disinfect for too long. Do not leave the Net immersed in disinfectant for
extended periods of time. Set a timer to alert you that the Net has been in the
disinfectant for the recommended amount of time.
• Agitate the Net while disinfecting. Agitate the Net in the solution for at least
2–3 minutes to ensure thorough disinfection of the sensor array (move the Net
in the liquid by lifting it up and down, or shake the bucket).
• No strong solvents. Do not use acetone or other strong solvents on the Geodesic
Sensor Net.
• No rubbing alcohol. Isopropyl alcohol will cause the sponges to disintegrate.
• Keep connector dry. Do not immerse or rinse the Net connector.
• Do not autoclave any part of the Geodesic Sensor Net. Most epoxies and cable
insulations will not withstand steam sterilization.
Screening Subjects/Patients
The Net should be applied only to subjects/patients who have dry, freshly washed
hair that contain no styling products such as gel or hair spray. In general, EGI
recommends that subjects/patients use no hair treatments beyond basic shampoo (for
example, heavy conditioners can cause higher impedances).
Request that subjects wear no facial foundation on the day of the session; the makeup
may stain the sponges of the GSN.
