Setup
Charging the Device
Before first use, fully charge the electric toothbrush. Connect the provided USB charging cable to the charging port at the bottom of the toothbrush handle and plug the other end into a compatible USB power source (e.g., mobile power bank, USB port, wall charger, notebook). The indicator lights will show charging progress. A full charge typically takes several hours. The device features an IPX6 waterproof rating, making it safe for use in wet environments, but ensure the charging port is dry before charging.

Attaching Brush Heads

Brushing Timer Feature
The LAMJAD Electric Toothbrush includes a built-in brushing timer to ensure you brush for the dentist-recommended two minutes. The device will pause briefly every 30 seconds to signal you to move to a different quadrant of your mouth, and will automatically shut off after two minutes of continuous operation.
Using the Scaler Heads
For targeted cleaning of plaque and calculus, attach either the pointed scaler head or the flat scaler head. Use these heads gently on tooth surfaces, focusing on areas with buildup. Do not apply excessive pressure. These are intended for surface cleaning and should not replace professional dental cleanings.

Maintenance
Cleaning the Toothbrush
After each use, rinse the brush head thoroughly under running water. Wipe the toothbrush handle with a damp cloth. Do not immerse the entire handle in water for extended periods, despite its water resistance. Ensure the charging port is dry before charging.
Storage
Store the toothbrush in a clean, dry place away from direct sunlight and extreme temperatures. It is recommended to replace toothbrush heads every 3 months, or sooner if bristles become frayed.
