Charging and Operating
This toothbrush is electrically safe and designed for use in
the bathroom.
• You may use your toothbrush right away or charge it
briefly by placing it on the plugged-in charger (f).
Note: In case the battery is empty (no charging light
illuminated (e) while charging or no reaction when
pressing the on/off button (c)), charge at least for 30
minutes.
• The charge indicator light (e) flashes green while the
handle is being charged. Once it is fully charged, the
light turns off. A full charge typically takes 12 hours
(picture 1).
Note: After deep discharge, the charge indicator light
might not flash immediately; it can take up to 30 min-
utes.
• If the battery is running low, the charge indicator light
(e) flashes red for a few seconds when turning your
toothbrush on/off and the motor is reducing its speed.
Once the battery is empty, the motor will stop; it will
need at least a 30-minute charge for one usage.
• You can always store the handle on the plugged-in
charging unit; a battery overcharge is prevented by
device.
Note: Store handle at room temperature for optimal battery
maintenance.
Caution: Do not expose handle to temperatures higher
than 50 °C. Recommended ambient temperature for
charging is 5 °C to 35 °C.
