Operating Instructions

1. Powering On/Off

• To turn on: Press the Power button once.
• To turn off: Press and hold the Power button for at least three seconds.

2. Selecting a Brushing Mode

The toothbrush features five performance modes. Press the Power button repeatedly (after turning on) to cycle through the modes. The indicator light next to the selected mode will illuminate.

• Sensitive: Softer cleaning, recommended for first-time users or those with sensitive teeth/gums.
• Clean: Standard mode for daily dental care and thorough cleaning.
• White: Designed to remove surface stains and whiten teeth.
• Polish: A 1-minute mode for polishing teeth.
• Massage: Gentle massage for healthy gums.

3. Brushing Technique

Apply a small amount of toothpaste to the brush head. Place the bristles against your teeth at a slight angle towards the gumline. Move the brush slowly across each tooth, allowing the sonic vibrations to do the work. Do not scrub vigorously.

4. Smart Timer

The built-in smart timer ensures you brush for the dentist-recommended 2 minutes. The toothbrush will pause briefly every 30 seconds to signal you to move to another quadrant of your mouth (upper right, upper left, lower right, lower left). After 2 minutes, the toothbrush will automatically turn off.

Maintenance

1. Cleaning the Toothbrush

• After each use, rinse the brush head thoroughly under running water.
• Wipe the toothbrush handle with a damp cloth. Do not submerge the handle in water for extended periods, despite its IPX7 rating.
• Ensure no toothpaste residue builds up around the metal shaft.

2. Replacing Brush Heads

Dentists recommend replacing your toothbrush head 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 on until it clicks.

3. Storage

Store the toothbrush in a dry place. For travel, use the provided travel case to protect the toothbrush and brush head.
