This instruction manual introduces the use of the oral irrigator, including the product's safety precautions, usage methods, maintenance methods, etc.
The Panasonic EW-DJ40 is a rechargeable oral irrigator designed for cleaning teeth and gums. The device features a built-in battery that charges via an adapter and offers multiple pressure settings to suit different needs, including a gentle mode for sensitive gums.
To operate the unit, users must first charge it until the indicator light turns on. Water should be added using tap or warm water (not exceeding 40°C), and the nozzle inserted securely. The device is operated by tilting the head slightly forward to prevent splashing and pressing a power switch located at the base of the handle. This manual is written in Chinese.
It takes approximately 8 hours to complete a full charge.
The battery has an estimated lifespan of about 3 years, though this may vary based on usage and storage.
You should replace the nozzle every 6 months or if the tip becomes deformed.
