service, if you handle it carefully. The following are precautions 

that should be observed:

•  Clean the product thoroughly after each bath. Rinse with warm 

water and dry with a soft, dry cloth. Never store the product 

when it is wet.

•  Do not subject the unit to excessive force, shock, dust or ex-

treme temperature or humidity. This may result in malfunction, 

shorter electronic lifespan, damaged battery and distorted parts.

•  Do not tamper with the unit’s internal components. This will
