or ting\fing sensati\hon caused by the high‑speed vibr\hations. The 
sensation shou\fd su\hbside after you use the toothbrush severa\f 
more times.
•	 When in use, the main unit of \hthis toothbrush emits a very weak 
e\fectric current (ionic \hcurrent) in the ora\f cavity.
•	 Touching the ion pan\he\f with your hand when you ho\fd the main 
unit to brush your teeth causes a \hvery weak e\fectric current (ionic \h
current) to flow between your teeth and the b\hrush head.

•	 The ion \famp on the \hmechanism that gene\hrates the very weak 
e\fectric current (see fig\hure above) turns on or b\finks to indicate 
whether ionic power is being app\fied\h to the teeth.
