Before first use, fully charge the toothbrush. Connect the DC charging cable to the charging port at the bottom of the handle and plug the other end into a 5V USB adapter (not included). The indicator light will show charging status. A full charge takes approximately 2 hours and provides up to 45 days of use.

The toothbrush offers a long battery life, providing 45 days of use from a 2-hour charge.

2. Attaching the Brush Head

Align the brush head with the metal shaft on the toothbrush handle and push down firmly until it clicks into place. Ensure it is securely attached before use.

Operating Instructions

1. Power On/Off and Mode Selection

• Press the power button once to turn on the toothbrush. It will start in the last used mode.
• Press the power button repeatedly within 5 seconds to cycle through the 5 modes: Clean, Sensitive, White, Polish, Massage.
• To turn off the toothbrush, press and hold the power button for 2 seconds, or press the power button after cycling through all modes.

2. Brushing Technique

• Wet the bristles and apply a small amount of toothpaste.
• Place the brush head against your teeth at a slight angle towards the gum line.
• Turn on the toothbrush. Gently move the brush head slowly across each tooth, allowing the sonic vibrations to clean. Do not scrub.
• The smart timer will pause briefly every 30 seconds to indicate when to move to a different quadrant of your mouth.
• The toothbrush will automatically turn off after 2 minutes, signaling the completion of the recommended brushing time.

The smart timer guides you through a 2-minute brushing cycle with 30-second quadrant reminders.

3. Using the Tongue Cleaner

After brushing your teeth, use the included tongue cleaner to remove bacteria and freshen breath. Gently scrape from the back of your tongue forward, rinsing the cleaner after each pass.

Using the tongue cleaner helps improve oral health by removing bacteria and freshening breath.

Maintenance

1. Cleaning the Toothbrush

• After each use, rinse the brush head thoroughly under running water.
• Remove the brush head and rinse the metal shaft area on the handle.
• Wipe the handle with a damp cloth. Do not immerse the handle in water for extended periods, despite its IPX7 rating, to prolong its lifespan.

The IPX7 waterproof rating allows for safe rinsing and use in wet environments.

2. Replacing Brush Heads

Dentists recommend replacing brush heads every 3 months, or sooner if the bristles become frayed. To replace, simply pull the old brush head off the handle and push a new one into place.

The product includes eight replacement brush heads, providing a supply for approximately two years.

3. Storage

Store the toothbrush in a dry place when not in use. Use the provided travel case for hygienic storage and protection during travel.
