4.6 Isolation Transformer
All EGI systems include one or more isolation transformers (medical
grade Toroid W Series), and all EGI components,
except the FICS ,
must plug into an isolation transformer to provide the attached
components with isolation from mains power for patient safety.
Note: If more than one isolation transformer is included, it is used to isolate
any optional event related potential (ERP) components (for research only)
from the EEG components.
