Important information
►Notice
•Do not put salt, mouthwash or other chemicals into the
water tank. Doing so may cause malfunction.
• Do not dry the main unit with a dryer or a fan heater.
Doing so may cause malfunction or deformation of the
parts.
• Store the appliance in a place with low humidity after
use. Failure to do so may cause malfunction.
• About tooth tartar
Please use together with a toothbrush.
It is hard to remove tooth tartar or dental calculus
attached to the tooth surface just by a water jet, so a
toothbrush is required to brush the teeth.
It is recommended to clean inside your mouth with the
water jet after brushing your teeth.
• About bleeding gums
Initially bleeding may occur even with healthy gums.
This is caused because the gums are not used to such
stimulation. The bleeding will normally stop within
1 or 2 weeks of use. There may be a problem with
the gums (periodontal disease, etc.) if the bleeding
continues for over 2 weeks. In such cases, stop using
the appliance andconsult a dentist.
