Precautions when using electric toothbrushes: 1. If the charge is less than 20%, the charging indicator will flash red. Please charge the electric toothbrush in time. Do not use the toothbrush until it cannot be turned on at all before charging, as this will affect battery life. 2. When not in use for a long time (e.g. longer than a month), the toothbrush should be charged to 40-60% for storage and recharged once a month. 3. Rinse and dry after brushing your teeth. The soaking time should not exceed 10 minutes. Do not use the toothbrush in hot and humid environments, as hot water vapor can penetrate the electric toothbrush more easily and cause motor damage. 4. Clean the groove of the lower sealing ring at least once a month (with cotton swabs and alcohol) to prevent limescale, toothpaste, etc. from accumulating at the charging port and affecting charging performance. 5. When using an electric toothbrush, make sure that the bristles are only slightly against the teeth. Do not apply pressure to avoid damaging the enamel. 6. After the correct insertion of the brush head, there is a small distance between the brush head and the housing (usually less than 0.5 mm). This is normal. Do not press the brush head firmly to the housing. 7. Store the electric toothbrush in a ventilated and dry place after use. Avoid high temperatures and strong sunlight. 8. To charge the electric toothbrush, use a 5V 1.5A plug and the charging cable provided by us. In case of poor contact, you can turn the charging cable. If charging does not work, please contact us.
