Operation
1. Starting a Meditation Session

- Free Practice: Customize the duration of your meditation session up to 90 minutes.
- Guided Practice: Engage in structured sessions, including an 8-week meditation program, each providing unique audiovisual biofeedback.

It also displays two practice methods: 'Free Practice' with customizable duration and 'Guided Practice' offering an 8-week program with unique audiovisual biofeedback, illustrated with various scenic backgrounds.
2. Understanding Real-Time Feedback
During your session, the headband provides immediate visual and auditory feedback.

3. Brainwave Tracking
The app provides real-time brainwave analysis, displaying data for various frequency bands including Delta, Theta, Alpha, Beta, Gamma, and SMR. This allows you to observe how your brain activity correlates with your meditation state.

4. Meditation Tracker Feature
Utilize the Meditation Tracker to monitor your meditation performance while playing audio from any third-party application. The headband will track your brainwaves and generate a detailed report after your session.

Maintenance
Cleaning
Gently wipe the headband and electrode areas with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials. Ensure the device is completely dry before storing or recharging.
Storage
When not in use, store the headband in its portable storage case to protect it from dust and damage. Store in a cool, dry place away from direct sunlight.
Battery Care
To prolong battery life, avoid fully discharging the headband frequently. If storing for an extended period, charge the battery to approximately 50% every few months.
Troubleshooting
- Connectivity Issues: Ensure Bluetooth is enabled on your device and the headband is charged. If connection drops, try restarting the app and the headband. Ensure the electrodes have good contact with your skin.
- App Not Found (Android): Verify your Android OS version is 10 or higher. If the app is not found on the Google Play Store, contact SereniBrain customer support for alternative download instructions.
- Inaccurate Readings: Ensure the headband is worn correctly and the electrodes are making firm, consistent contact with your skin. Clean the electrode areas if necessary.
- Forehead Marks: Temporary marks on the forehead from the electrodes are normal due to skin contact. These should disappear shortly after removing the headband. If discomfort persists, adjust the headband's fit.
