Do not use brainLight Touch Synchro together with the visualization glasses in the following cases: epilepsy or similar seizure disorders, photosensitivity, having a pacemaker, or pregnancy. Thanks to the acoustic signals delivered through the headphones, the brainLight audiovisual system remains effective without the visualization glasses, though the effect is less intense. Do not use brainLight Touch Synchro in the following cases: under the influence of alcohol, drugs, or psychedelics; if you have experienced brain injury or brain surgery; if you feel strong discomfort; if you have a high fever; or if you are currently undergoing psychological or psychiatric treatment (only after consulting your doctor). If your Touch Synchro is paired with a Shiatsu massage chair, do not use the massage function in the following cases: pregnancy, acute back pain, osteoporosis, thrombosis or similar venous disorders, body weight over 120 kg, or any medical contraindications regarding massage. In these cases, choose only programs without massage — the chair will move into a semi-reclined position for the duration of use, but will not massage.
