Starting a Circl test
Set Up for Success
Charge the Headset
-
Locate the charging port on the underside of your headset.
-
Connect the charging cable to the headset and a power source.
-
The headset will be fully charged within two hours.
💡 Tip: A full charge ensures the best connection and test accuracy.
Install the Circl App
-
Open the Apple App Store and search for “Circl Brain.” You can also scan the QR code included in your Circl kit.
-
Download and open the app on your device.
-
Sign in with your Apple ID or create a new Circl account.
Using the Headset
Once your headset is charged and the Circl app is installed, you’re ready to set up your test.
Apply the Neurodiagnostic Paste
-
Use the Circl neurodiagnostic paste provided in your kit.
-
With your fingertip, apply a small amount of paste to each of the four electrode points: the two spiky electrodes on the back of the headset, and the gold-plated areas inside each ear clip.
-
Make sure each area has a thin, even layer of paste — enough to fully cover the contact area but not too much.
✅ Good coverage ensures accurate brainwave readings.
Power On and Fit the Headset
-
Press and hold the power button for two seconds until a green light appears.
-
Hold the headset from the back and position it just above your eyebrows.
-
Gently stretch the arms around your head for a comfortable fit.
-
Wiggle the back electrodes slightly to make sure they touch your scalp.
-
Attach the ear clips to both ears.
Once fitted, open the Circl app — you’re ready to start your test.
