[. . . ] Never open batteries, never solder or weld batteries. If you do not intend to use the appliance for an extended period, remove the batteries. In the event of the batteries leaking acids, first put on a pair of protective gloves. Then clean the battery compartment and the battery contacts with a dry cloth. [. . . ] Divide your jaws into four sections (quadrants): upper left, upper right, lower left and lower right. Begin in one quadrant: Place the brush head 1 on your gums and move the brush upwards/ downwards from the gums to over the crown of the tooth. Proceed in this manner on both the inside and the outside surfaces of the tooth. Start again from the gums for each individual tooth. Do not forget the back surfaces of the rear molars. To clean the chewing surfaces, direct the rotating brush head with light pressure over the chewing surfaces. After 30 seconds the toothbrush briefly interrupts its operation twice, to signalise to you that you should start to clean the next quadrant. Clean all jaw quadrants with the same technique. After two minutes the toothbrush briefly stops its operation 4 times. This informs you that you have complied with the dental recommendation of two minutes cleaning. First take the toothbrush out of your mouth when it has stopped. After use, clean the brush heads 1 thoroughly under running water. Clean the hand element 2 only with a soft and lightly moistened cloth. After use, clean the brush heads 1 thoroughly under running water. We recommend cleaning the brush heads 1 in a standard commercial cleaning fluid for prosthetics every 2 - 4 weeks. After about 3 months, at the latest however when the bristles bend outwards, you should fit a new brush head 1. Do not use sharp objects to remove dried-on toothpaste from the hand element 2, they could damage the seals and thus the appliance. When the movement become noticably weaker, the batteries must be exchanged. Always use batteries of the same type and never use a new and an old battery together. Pay heed to the polarity when inserting batteries. This is marked on both contacts inside the battery compartment. Do not dispose of the appliance in your normal domestic waste.
