1Insert main unit so it stands
upright in the charging section.
The charging indicator will light up.
•Be sure to place the main unit upright. If
the main unit is tilted or not in direct contact
with the charger, the main unit may not
charge properly.
•Charging is completed in about 15 hours.
•The lamp does not go off even when
charging ends.
•The main unit will provide an operation time
of approximately 15 minutes of use when
the battery is fully charged. (The operating
duration will become shorter as the
batteries get older.)

2Disconnect the power plug after charging is
completed.
•The battery performance will not be affected even if it is
charged for more than 15 hours.
Notes
•When using the appliance for the first time or if it has not been
used for more than half a year, the charging indicator may not
light up for several minutes after charging starts or the
operating time may become shorter. In such cases, charge the
battery for 23 hours or more.

Battery performance may decrease under extremely low or high
temperatures, and the battery may not charge properly.
How to use
1

If the appliance is not used for more than 30 days, or after
the appliance has been fully charged from its fully
discharged state, the mode is initialized to air in (soft).
(When the battery is drained, the mode will be reset but this
is not a fault.)
•If you want to use a different mode, press the mode switch
until it changes to the desired setting. Pressing the mode
switch will change the mode from air in (soft) to air in
(normal) to jet.
Mode Description
jet mode
•This mode is for removing food particles
trapped between the teeth.
air in (normal) mode

water will come out of the ventilation
hole instead of the nozzle. (The
ventilation hole in the rear of the
main unit allows for easier water
suction of the hose.)
