plug does not fit into the outlet, reverse the plug. If it still does not
fit, contact a qualified electrician. Do not attempt to modify the plug
in any way.
a) A short power-supply cord (or detachable power-supply cord)
should be used to reduce the risk resulting from becoming
entangled in or tripping over a longer cord.

may be used if care is exercised in their use.
c) If a longer detachable power-supply cord or extension cord
is used:
1) The marked electrical rating of the cord set or extension
cord should be at least as great as the electrical rating of the
appliance;
2) The cord should be arranged so that it will not drape over
the countertop or table where it can be pulled on by children
or tripped over unintentionally; and
3) If the appliance has a grounded plug, the cord set or exten-
sion cord should also be a grounded 3-wire cord.

Set-up/wall bracket
The charger may only be operated free-standing if used in dry
rooms.
In damp rooms, especially in the vicinity of water (bath), the charger 
must be firmly fixed to the wall to protect it from falling into water.
1) Pull the wall bracket downward from the charger :
2) Using the screw holes of the wall bracket , mark the spacing
for the boreholes on the wall. Check to ensure that there is a
power socket in close vicinity.
3) Before drilling the holes, check to ensure that there are no electri-
cal cables or water pipes behind the markings.
4) Use a 5 mm drill bit to drill the required holes and insert the
wall plugs.
5) Secure the wall bracket using the screws provided.
6) After you have attached the wall bracket , guide the power cord
through the right or left cut-out in the charger (see magnification
on the fold-out page). Using the guide rails, slide the charger 
onto the wall bracket .
7) Ensure that the power cord is not trapped and that it lies properly

using it for the first time. The charge indicator on the front of
the handset lights up red during the charging process.
6) Use the handset repeatedly without charging the battery until
the performance becomes noticeably weaker or the toothbrush
stops working and the charge indicator blinks red. Then re-
charge the battery for 14 - 16 hours.
When the appliance is fully charged, the charge indicator 
lights up green.
7) Charge and discharge the toothbrush completely 3 times.
The battery will then have reached its full capacity.

Brushing teeth
Due to the unaccustomed effect of the toothbrush, there may be some
initial gum bleeding. This is normal. If it continues for more than two
weeks, you should consult your dentist.
1) Place the brush head on the handset.
2) Moisten the brush under flowing water.
3) Put a little toothpaste onto the wet brush.
To avoid spraying, do not turn on the appliance until it is in your
mouth
4) Use the On/Off switch to select the desired operating mode
(see „Operation" section).
This toothbrush has a 30-second interval timer, so that all four jaw
quadrants can be cleaned evenly.
5) Divide your mouth into four parts (quadrants): upper left, upper
right, lower left and lower right.

DAZD 3.7 Li B2 US-EN │ 13 ■
6) Start in one quadrant:
Start with the brush head on your gums, and move the brush
upwards/downwards from the gums to the crown of the tooth.
Proceed in this manner on the inside and
the outside of the tooth. Start again at the gums for each indi-
vidual tooth.
Do not forget to brush the back of the rear molars.
To clean the chewing surfaces, guide the oscillating brush head
over the chewing surfaces with a little pressure.
7) After 30 seconds, the toothbrush stops briefly to signal that
you should start cleaning the next quadrant. Clean each jaw
quadrant using the same technique.
8) After two minutes, the toothbrush stops briefly 4 times. This
signals that you have complied with the dental recommendation
of two minutes cleaning.
9) Press the On/Off switch repeatedly until the toothbrush
stops.
10) Then take the toothbrush out of your mouth.
11) After use, rinse the brush head thoroughly under running
water.
12) Detach the brush head from the handset.
To clean the drive shaft and the handset, allow a little water
to flow over them. Hold the handset so that the drive shaft is
pointing downward.
Regularly massage your gums. This promotes blood circulation and
helps to keep them healthy. Set the mode to "Pulse" and guide the
moistened brush over your gums with light pressure.

surfaces.

DAZD 3.7 Li B2 US-EN │ 15 ■
2) Remove the brush head from the handset. After use, clean the
brush heads thoroughly under running water. We recommend
cleaning the brush heads in a standard commercial denture
cleaning fluid every 2 - 4 weeks. A new brush head should be
used after about 3 months, and the brush head must always be
replaced when the bristles start to bend outwards.
3) To clean the drive shaft and the handset, allow a little water
to flow over them. Hold the handset so that the drive shaft is
pointing downward.
Traveling case
If you wish to take the toothbrush with you on a trip, you can pack
the hand element and two brush heads in the traveling case.
When the battery is fully charged, you can use the toothbrush for
60 minutes without recharging. This is only an approximate value.
Depending on the pressure used when brushing your teeth, the max-
imum operating time may vary.
Disposal
Electrical devices may not be thrown away as part of normal house-
hold trash. If you can no longer use your electrical device, dispose
of it in accordance with the legal provisions applicable in your
state. This will allow you to ensure that old electrical devices are
recycled and environmental pollution is kept to a minimum. Further
information about disposal is available on the Internet at
www.epa.gov.
The integrated recharchable battery cannot be removed for disposal.
The packaging is made from environmentally-friendly
material and can be disposed off at your local recycling
plant.
