Do not use this device while driving, operating machinery, or performing any activity that requires muscular control. Using the device during such activities may lead to unexpected muscle movements, especially if electrode pads become loose or contact changes suddenly. Consult with a clinician before using this device if you have active or suspected cancer, or any unexplained pain with a history of cancer, in the treatment area. Stimulation applied over or near malignant or suspected malignant areas could potentially stimulate tumor growth or spread cancer cells. Avoid using this device simultaneously with high-frequency diagnostic or therapeutic equipment commonly found in hospitals. This includes MRI machines, ultrasound devices, and other high-frequency machines. Concurrent usage can cause burns at electrode sites and may damage the device. Do not use the device within 1 meter of equipment emitting electromagnetic fields, such as shortwave radios, microwave ovens, TVs, and high-fidelity (hi-fi) speakers. Such proximity can cause instability in the device’s operation and may interfere with its functionality. If the device starts behaving unusually, move it away from other electronic devices to restore normal function. Do not place electrodes near the thorax area. Electrical currents in this area may raise the risk of cardiac fibrillation, a severe irregular heartbeat. Also, avoid placing electrodes across or through the head, over the eyes, around the mouth, or on the front of the neck, particularly near the carotid sinus. If you experience any adverse reactions or unusual discomfort while using the device, discontinue its use immediately. Seek advice from a healthcare professional to assess any risks or necessary adjustments.
