1. Product Overview
The Philips Sonicare One Electric Toothbrush is designed to provide an enhanced brushing experience compared to a manual toothbrush. It features micro-vibrations and contoured bristles for gentle yet effective cleaning and polishing. Its sleek design and portable travel case make it ideal for both home use and travel.
This model includes a 2-minute timer with 30-second notifications to guide your brushing, ensuring you clean each quadrant of your mouth thoroughly. Powered by a single AAA battery, it offers an impressive battery life of up to 3 months.
2. Setup Instructions
- Unpack the Toothbrush: Carefully remove all components from the packaging.
- Insert Batteries: The toothbrush operates on a single AAA battery. To insert or replace the battery, twist off the bottom cap of the handle. Insert the AAA battery, ensuring correct polarity (+/-), then securely twist the cap back on.
- Attach Brush Head: Select a brush head and firmly push it onto the metal shaft at the top of the toothbrush handle until it clicks into place. The Philips Sonicare One is compatible only with Philips One by Sonicare replacement brush heads.


3. Operating Instructions
- Prepare for Brushing: Wet the brush head and apply a small amount of toothpaste.
- Start Brushing: Press the power button on the handle to activate the micro-vibrations.
- Brush Your Teeth: Gently guide the brush head across all surfaces of your teeth. The toothbrush will buzz every 30 seconds, signaling you to move to a different quadrant of your mouth (upper right, upper left, lower right, lower left).
- Complete Brushing Cycle: A longer buzz at 2 minutes indicates that the recommended brushing time is complete, and the toothbrush will automatically turn off.
- Rinse: After brushing, rinse your mouth and the brush head thoroughly under running water.


4. Maintenance
- Clean the Brush Head: After each use, rinse the brush head thoroughly under running water to remove any toothpaste residue.
- Clean the Handle: Wipe the toothbrush handle with a damp cloth as needed. Do not submerge the entire handle in water.
- Replace Brush Head: For optimal performance and hygiene, replace the brush head every three months, or sooner if the bristles appear frayed or worn.
- Battery Replacement: The AAA battery typically lasts for 3 months. Replace it when the toothbrush's performance diminishes.
- Travel Case: Utilize the sleek travel case to protect your toothbrush and brush head when traveling.

5. Troubleshooting
If your Philips Sonicare One Electric Toothbrush is not functioning as expected, please check the following:
- No Power: Ensure the AAA battery is correctly inserted with the proper polarity. If the battery is old, replace it with a new one.
- Weak Vibrations: This may indicate a low battery. Replace the AAA battery.
- Brush Head Detaches: Ensure the brush head is firmly pushed onto the handle's shaft until it clicks.
