What is it indicated for?

The Byteflies Kit is intended for prescription use in the home, healthcare facility, or clinical research environment to

acquire, record, and transmit electrical activity of the brain by placing non-invasive electrodes on the head of patients. It acquires, records and transmits two channels of electroencephalogram (EEG) data. The medical use of data acquired by the Byteflies Kit is to be performed under the direction and interpretation of a licensed medical professional. The Byteflies Kit does not provide any diagnostic conclusions about the patient’s condition.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
