Welcome to Crest!
Your toothbrush has been carefully designed to offer you and your
family a unique brushing experience that is both safe and effective.
When using electrical products, however, basic safety precautions
should always be followed.
Read all instructions before using.
WARNING
• Do not place the charger in water or liquid or store where it can fall or
be pulled into a tub or sink. Do not reach for it when fallen into water.
Unplug immediately.
• This appliance contains batteries that are non-replaceable.
• Do not disassemble the product except when disposing of the
battery. When taking out the battery for disposal of the unit, use
caution so as not to short the positive (+) and negative (–) terminals.
• When unplugging, always pull the power plug instead of the cord.
Do not touch the power plug with wet hands. This can cause an
electric shock.
• If you are undergoing treatment for any oral care condition, consult
your dental professional prior to use.
• This toothbrush is a personal care device and is not intended for use
on multiple patients in a dental practice or institution.
• It is recommended to use individual brush handles for each family
member.
• This appliance contains magnets and generates magnetic fields. If
you use a medical device or have an implanted medical device and
you have questions about the safe usage of this toothbrush, consult
the medical device manufacturer or a physician.
To avoid brush head breakage which may damage teeth:
• Prior to each use, ensure the brush head fits well. Discontinue use of
the toothbrush, if brush head no longer fit properly. Never use without
a brush head.
• If the toothbrush handle is dropped, the brush head should be
replaced before the next use even if no damage is visible.
• Replace brush head every 3 months or sooner if brush head
becomes worn.
• Clean brush head properly after each use (see “Cleaning
recommendations” paragraph). Proper cleaning ensures the safe use
and functional life of the toothbrush.
IMPORTANT
• Periodically check the entire product/cord
for damage. Avoid sharp bending,
jamming and squeezing of cord. If the
product/cord is damaged, take it to a
Braun/Crest Service Centre. A damaged or
non-functioning unit should no longer be
used. Do not modify or repair the product.
This may cause fire, electric shock or injury.
• Usage by children under age 3 is not
recommended. Toothbrushes can be used
by children and persons with reduced
physical, sensory or mental capabilities or
lack of experience and knowledge, if they
have been given supervision or instruction
concerning use of the appliance in a safe
way and understand the hazards involved.
• Cleaning and maintenance shall not be
performed by children.
• Children shall not play with the appliance.
• Use this product only for its intended use
as described in this manual. Do not use
attachments which are not recommended
by the manufacturer. Only use charger

Charging and Operating
Your toothbrush is electrically safe and designed for use in the
bathroom.
• Plug the charging unit (f) into an electrical outlet and place the handle
(e) on the charging unit (picture 1).
• During charging the indicator light (d) fades in/out or all 3 mode
indicators fade in/out (depending on model). Once the toothbrush is
fully charged the light(s) turn(s) off. A full charge can take up to 24
hours and enables up to 2 weeks of regular brushing (twice a day, 2
minutes).
• If the battery is running low, the charge indicator (d) light is flashing or
all 3 mode indicators are flashing for a few seconds after turning your
toothbrush off (depending on model). It is recommended to recharge
the toothbrush by then.
• To maintain the maximum capacity of the rechargeable battery,
unplug the charging unit and fully discharge the handle with regular
use at least every 6 months.

Using your toothbrush
Brushing technique
• Slide the brush head on the handle. Wet brush head and apply any
kind of toothpaste. To avoid splashing, guide the brush head to your
teeth before switching on your toothbrush.
• Place the brush head on the outside surface of your upper teeth. The
toothbrush bristles should be placed against the teeth at a slight
angle towards the gumline.
• Turn your toothbrush on and start brushing in a slightly circular
motion (picture 4). Apply light pressure during brushing. After a few
seconds, guide the bristles to the next section. Brush inside, outside
and chewing surfaces of your teeth with the same motion throughout
the mouth for the recommended 2 minutes.
• To avoid splashing, turn your toothbrush off before removing from the
mouth by pressing the on/off button (b).
You may experience a slight tickling or tingling sensation when you
first use your toothbrush. This will subside as your teeth and gums
will become accustomed to the cleaning experience.
In the first few days of using any electric toothbrush, your gums may
bleed slightly. In general, bleeding should stop after a few days.
Should it persist after 2 weeks, please consult your dentist or your
dental hygienist.
Brushing modes (depending on model)
Your toothbrush offers different brushing modes for varying oral care
needs:
«Daily Clean/Clean» – Gentle, effective mouth cleaning.
«Whitening/Stain Removal» – Whitening mode for occasional or
everyday use.
«Sensitive» – Gentle, yet thorough cleaning for sensitive areas
When pressing the on/off button (b), your toothbrush automatically
starts in «Daily Clean» mode. To switch mode(s) successively press
the on/off button. To turn your toothbrush off, press and hold the on/
off button until the motor stops (picture 2).
Timer
A short stuttering sound at 30-second intervals (one break) reminds
you to brush all four quadrants of your mouth equally (picture 3).
A long stuttering sound (two breaks) indicates the end of the
professionally recommended 2-minute brushing time.
If the toothbrush is turned off during brushing, the elapsed brushing
time will be memorized for 2 minutes. When pausing longer than 2
minutes the timer resets.
Brush head
Crest brush head
The Crest brush head (a) is recommended for everyday deep
cleaning. Its bristles provide a thorough cleaning between your teeth,
tooth surfaces and along the gumline.
The blue indicator bristles help you to monitor brush head
replacement need. With proper brushing, twice a day for two
minutes, the blue color will fade halfway approximately within 3
months, signaling it is time to replace your brush head.
Cleaning recommendations
Switch off the handle and remove the brush head. Rinse both brush
head and handle thoroughly under running water. Wipe them dry
before reassembling. Place the cleaned and dried handle on the
charging unit. From time to time, clean the charging unit (f) with a
damp cloth. The charging unit should never be placed in water
(picture 5).
Subject to change without notice.
