- Start below 60% device volume in a quiet, safe, stationary setting. Never use these exhibits while driving, cycling, or operating equipment.
- Stop immediately if you experience discomfort, dizziness, nausea, anxiety, headache, ringing or pressure in the ears, visual strain, or any unusual symptom.
- If you have epilepsy or a seizure history, sensitivity to repetitive sound or visual patterns, tinnitus, hyperacusis, or a neurological condition, seek guidance from a qualified clinician before use.
- HelioSynth is a creative and educational instrument—not a medical device or medical care—and does not diagnose, treat, cure, or prevent any condition.
