Operating Instructions

(Household) 

Sonic Vibration Toothbrush

Model No.

 

EW-DL90
EW-DL91

Before operating this unit, please read these instructions 
completely and save them for future use.

► For your personal dental care

Thank you for purchasing the Sonic Vibration Toothbrush.
The Sonic Vibration Toothbrush is a new kind of electric 
toothbrush designed for those who wish to keep their teeth 
clean and healthy. This appliance will enable you to maintain 
good dental hygiene, which is as important as other forms of 
personal hygiene.

► Sonic Vibration Toothbrush Technology

The Sonic Vibration Toothbrush incorporates the innovative 
“linear motor” technology that uses magnetic attraction and 
repulsion to provide outstanding performance. The brush’s 
31,000 horizontal strokes per minute help remove plaque gently 
yet effectively.

► Before use

This high-speed, vibrating, electric toothbrush is different from 
conventional electric toothbrushes.
Therefore:
• You only need to lightly press the bristles against your teeth for 

brushing.

• When first using this appliance, some may experience a 

tickling or tingling sensation caused by the high-speed 
vibrations. The sensation should subside after you use the 
toothbrush several more times.

• Be sure to switch off the appliance and remove the plug from a 

household outlet before performing any maintenance. Failure to 
do so may result in electric shock.

• Cleaning and user maintenance should not be made by children.

• Keep the appliance away from children.

• Do not use the charger in the bath. Doing so may result in 

electric shock.

• Do not touch or pull out the plug with wet hands. Doing so may 

result in electric shock.

• If the power cord of the charger is damaged, the entire charger 

should be discarded. The charger should be replaced.

• Do not wrap the power cord around the charger.

• Always ensure the appliance is operated on an electric power 

source matched to its rated voltage. Failure to do so may result in 
fire or electric shock.

• Clean the plug periodically so that dust does not accumulate in it. 

Such dust buildup may trap moisture over time and reduce the 
effectiveness of the insulation, thus resulting in overheating and 
fire.

• Do not modify, disassemble, or repair the appliance at any time 

except when disposing of it. Doing so may result in fire, electric 
shock, and/or burns.

• Do not place any metal objects, such as coins and clips, on the 

charger. Doing so may cause the objects to heat up, resulting in 
burns.
