WARNING

After removing the rechargeable battery, do not

keep it within reach of children and infants.

- The battery will harm the body if accidentally

swallowed.

If this happens, consult a physician immediately.

If the battery uid leaks out and comes in

contact with the eyes, do not rub the eyes, and

thoroughly rinse with clean water, such as tap

water.

- Failure to do so may cause eye injury.

Consult a physician immediately.

CAUTION

If the battery uid leaks out and comes in

contact with the skin or clothes, rinse o󰀨 with

clean water, such as tap water.

- Failure to do so may cause inammation.

Intended use

• Please use the appliance together with toothbrush. It

is hard to remove tartar or dental calculus attached to

the tooth surface just by a water jet, so a toothbrush is

required to brush the teeth. We recommend rinsing the

inside of your mouth with the water jet after brushing

your teeth.

• When you rst begin using the oral irrigator, you may

experience slight bleeding of the gums even though

your gums may be healthy. This is because your gums

are receiving stimulation by the oral irrigator for the rst

time. The bleeding should stop after one or two weeks

of use. Bleeding that persists for more than two weeks

may be indication of an abnormal condition of your

gums, such as periodontal disease. In this case, stop

using the oral irrigator and consult your dentist.

• 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. Leaving the appliance in a bathroom may cause

malfunction.

• Wrap the appliance in a towel or the like when carrying

it with you. Otherwise, the water may seep out, thus

wetting surrounding objects.

• Charge the appliance correctly according to these

Operating Instructions. (See pages 9 and 10

"Charging".)

• This appliance contains battery that is only replaceable

by skilled persons. Please contact an authorized

service centre for the details of repair.

• The following symbol indicates that a specic detachable

power supply unit is required for connecting the electrical

appliance to the supply mains. The type reference of

power supply unit is marked near the symbol.
