What is the Smartimer?
The Smartimer automatically stops your Sonicare toothbrush after the dentist-recommended brushing time of 2 minutes has elapsed. If you switch the toothbrush off at any time during the brushing cycle, for instance to rinse or apply more toothpaste, the Smartimer interrupts its timing and resumes where it left off when you switch the appliance back on again. Although a 2-minute brushing session is recommended for optimal results, you can always stop or restart the toothbrush at any time by pressing the power button. When the handle is placed in the charger, the Smartimer automatically resets to ensure a complete 2-minute brushing cycle the next time you use it. The Smartimer also resets itself if you stop your Sonicare toothbrush for more than 45 seconds.
