Setup
1. Charging the Toothbrush
Before first use, fully charge the toothbrush. Connect the provided USB-C cable to the charging port at the bottom of the toothbrush and plug the other end into a compatible USB power adapter (not included). The indicator light will turn on within 5-10 minutes of charging and will fully charge in approximately 3 hours. A single full charge can last up to 50 days when used on the default Mode 1, twice a day for two minutes each time.

2. Attaching a Brush Head
Align your chosen brush head with the metal shaft on the toothbrush handle and push it down firmly until it clicks into place. Ensure there is a 0.3 to 1mm gap between the handle and the brush head to allow for proper oscillation.
3. Activating/Deactivating Travel Mode
To prevent accidental activation during travel, the toothbrush features a travel mode. To activate or deactivate, press and hold the power button for approximately 3-4 seconds until the airplane icon appears or disappears. When in travel mode, the toothbrush will not turn on with a short press.

Operating Instructions
1. Power On/Off
Press the power button once to turn the toothbrush on. Press it again to turn it off.
2. Changing Brushing Modes and Intensity
While the toothbrush is on, double-press the power button to cycle through the available brushing modes. The Laifen Wave Special offers three distinct intensity modes, allowing you to select the most comfortable and effective setting for your needs.
3. Brushing Technique
The Wave Special utilizes 60° oscillations and up to 26,000 vibrations per minute to emulate the dentist-recommended Modified Bass brushing technique. Gently guide the brush head along your gumline, allowing the toothbrush to do the work. The smart timer will guide you through a 2-minute brushing cycle with a zone change reminder every 30 seconds.

4. Smart App Integration
Download the Laifen App to personalize your brushing experience. The app allows you to customize your brushing across 1,000 possible setting combinations, adjust vibration intensity, oscillation range, and oscillation speed. It also provides a Smart Brushing Timer and Zone Change Reminder to guide you to a comprehensive clean.

Maintenance
1. Cleaning the Toothbrush
After each use, rinse the brush head thoroughly under running water. Wipe the toothbrush handle with a damp cloth. The toothbrush is IP68 waterproof, allowing for easy cleaning and use in wet environments.
2. Brush Head Replacement
We recommend replacing the brush head every three months, or sooner if the bristles become deformed or damaged. Using a worn brush head can reduce cleaning effectiveness. The brush heads are coated in a soft food-grade TPE coating and feature ultra-fine bristles fitted with an advanced copper-free tufting process to prevent rusting.
