Step 1: Charging. Before the first use, ensure your toothbrush is fully charged. Connect the charging base to a power source using the adapter provided. Place the toothbrush handle on the charging base, ensuring the metal contacts on the handle align with those on the base. Let it charge for the recommended time, usually indicated in the user manual. Step 2: Brush Head Installation. Select a brush head suitable for your preferences and attach it firmly to the handle. Our toothbrush usually comes with multiple brush head options, so choose the one that best suits your needs – whether it's for sensitive teeth, deep cleaning, or gum care. Step 3: Power On. Press the power button on the handle to turn the toothbrush on. You might need to press and hold the button for a few seconds, depending on the model. Once the power is on, the toothbrush will activate, and you'll be ready to start brushing. Step 4: Apply Toothpaste. Apply your preferred toothpaste onto the bristles of the brush head. Make sure not to exceed the recommended amount. A pea-sized amount of toothpaste is usually sufficient for effective cleaning. Step 5: Brushing. Place the bristles of the toothbrush against your teeth at a slight angle towards the gum line. Turn on the cold light feature if your toothbrush has this functionality. Move the brush head gently in a circular motion, ensuring you cover all areas of your teeth and gums. Brush for the recommended duration, typically two minutes. Step 6: Rinse and Clean. After brushing, rinse your mouth thoroughly with water. Remove the brush head from the handle and rinse it under running water. Allow both the brush head and the handle to air dry before reassembling or storing. Step 7: Recharging. When the battery is low, recharge your toothbrush following the steps outlined in Step 1. Ensure your toothbrush is always adequately charged for optimum performance. Step 8: Maintenance. Regularly clean the handle and charging base with a damp cloth to remove any dirt or toothpaste residue. Replace the brush head as recommended by the manufacturer, usually every three to four months or when bristles show signs of wear. By following these steps, you can ensure proper usage and maintenance of your Intelligent Electric Toothbrush with Cold Light, helping you achieve a brighter, healthier smile!
