When using the Portal website to interact with the DevKit, it is strongly recommended that you use a Chrome internet browser. Other browsers are not guaranteed to work.
Once the cap is in its final configuration for recording neural data, you must tune the lasers. This operation configures the strength of each laser to ensure every detector is receiving an adequately strong signal.
NOTE:
Tune Lasers must be re-run each time the DevKit is placed on a different participant's head, or each time the DevKit has been re-adjusted on the same participant's head.
To tune the lasers:
- Make sure the headset is properly seated and aligned on the participant's head, and that any adjustments to improve coupling have already been made (see Getting the Best Signal).
- Make sure ambient light in the room has been reduced.
- In the Portal Flow tab, click Tune Lasers.
This process takes about 20 seconds. The participant should remain still during this process.
The Portal Flow UI display will proceed to the Data Acquisition Control Menu (displayed below). You are then ready to record data (see the Recording Data folder under User Interface Documentation).

After the Tune Lasers command runs, the lasers remain enabled. Do not remove the DevKit without disabling the lasers.
