2.2 Charging the Toothbrush
- Place the main unit onto the charging base.
- Connect the charger to a power outlet (100-240V AC compatible).
- The charging indicator will illuminate. A full charge takes approximately 17 hours.
- A full charge provides approximately 90 minutes of usage (about 22 days when used twice daily for 2 minutes each time).
- For a quick single use, a 4-minute charge provides enough power for one 2-minute brushing session.
- Important: Keep the charger away from water.
3. Operating Instructions
3.1 Brushing Technique
- Apply a small amount of toothpaste to the brush head.
- Place the brush head between your teeth and gums at a 45-degree angle, using the recommended 'Bath and Scrubbing Method'.
- Turn on the toothbrush. The linear sonic vibrations (approx. 31,000 brush strokes/minute) will clean your teeth.
- Gently move the brush across all surfaces of your teeth, allowing the vibrations to do the work. Do not scrub vigorously.
- Brush for 2 minutes, twice a day, for optimal results.

3.2 Brushing Modes
Your toothbrush offers two brushing modes:
- Normal Mode: For daily comprehensive cleaning.
- Soft Mode: For sensitive teeth and gums, providing a gentler cleaning experience.

3.3 Anti-Push Sensor
The toothbrush is equipped with an anti-push sensor. This feature helps to reduce the burden on your teeth and gums by alerting you if you apply too much pressure during brushing. Adjust your pressure if the sensor activates.
4. Maintenance and Care
4.1 Cleaning the Toothbrush
- The main unit of the Panasonic EW-DL39-W is IPX7 waterproof, meaning it can be safely washed under running water.
- After each use, rinse the brush head and the main unit thoroughly under water to remove any toothpaste residue.
- Wipe the main unit dry with a soft cloth.
4.2 Replacing the Brush Head
For optimal cleaning performance and hygiene, replace the brush head every 3 months, or sooner if the bristles become frayed or worn. Replacement brush heads are available from authorized Panasonic retailers.

5. Troubleshooting
If you experience issues with your Panasonic EW-DL39-W electric toothbrush, please consider the following common solutions:
- Toothbrush not turning on: Ensure the unit is fully charged. Connect it to the charger for at least 4 minutes for a quick charge, or 17 hours for a full charge.
- Reduced vibration strength: This may indicate a low battery. Recharge the toothbrush. If the issue persists after a full charge, the brush head might be worn and needs replacement.
- Brush head feels loose: Ensure the brush head is pushed firmly onto the metal shaft until it clicks into place.
- Excessive pressure warning (if applicable): If the anti-push sensor activates frequently, adjust your brushing technique to apply less pressure.
If these steps do not resolve the issue, please contact Panasonic customer support for further assistance.
