2 Turn the brush head nut clockwise until it is firmly tightened. If
the brush head rattles during use, tighten the nut further.
Charging your Sonicare\
Sonicare comes with the batteries completely discharged and should
be charged for at least 24 hours during the first few days of use.
C
1 To charge your Sonicare, place the handle in the charger with
the Sonicare logo facing forward. Be sure the bottom of the
handle sits back securely in the charger, making complete
contact.
C
◗ When the handle is placed incorrectly in the charger, the green
charge indicator LED may illuminate, but charging will not take
place.
Handles of other Sonicare models will not fit in this charger and will
therefore not charge effectively. Do not attempt to force a handle into
this charger as this will cause damage.
Using the appliance
Useful tips
◗ You can use your favorite toothpaste with your Sonicare.
◗ The brush head comes with a convenient travel cap. Remove the
travel cap from the brush head before turning on your Sonicare.
◗ Place the brush head in your mouth before turning on your
Sonicare, and be sure it is turned off before removing it from your
mouth, otherwise toothpaste may splatter.
◗ You may experience a slight tickling or tingling sensation after
using an electronic toothbrush such as Sonicare for the first time.
As you become accustomed to brushing with Sonicare this
sensation will diminish.
◗ Rinse the brush head and bristles after each use.
◗ Clean the brush head weekly, including under the nut.
◗ A fully charged Sonicare will provide approximately 2 weeks of
typical use (2 minutes of brushing twice a day), making it easy to
take your Sonicare along without the charger.
