The prongs are designed to penetrate through thick hair more easily and touch the scalp. #### T7 sensor The T7 sensor is fitted to the inside of the headset. It is designed to make contact with the skin just above your left ear. #### Reference sensors The reference sensors are designed to make contact with the skin just behind your left ear. Once you fit Insight, you can adjust the sensor arm so that the reference sensors make good contact with the skin. ### Storing the sensors When you’re not using Insight, remove the sensors and store them in the sensor pack. Doing this will stop the sensors from drying out. ### Removing the T7 and reference sensors The sensor pack includes an Allen key for removing the T7 and reference sensors. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://emotiv.gitbook.io/insight-2-user-manual/getting-started/insight-sensor-pack.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
