Philips SONICARE-PROTECTIVECLEAN-4300-HX6809 user manual

The flashing lights on your Philips Sonicare toothbrush may indicate different statuses:
1. Battery Status: If the battery light on your Sonicare toothbrush is blinking, this indicates that the battery is low and needs to be charged. Once plugged in, the flashing will gradually become steady as the battery is charged.
2. Replacement Reminder: If it's the brush head symbol that's blinking, it means you need to replace the toothbrush head.
3. Pressure Sensor: Some Sonicare models have a light at the bottom of the handle that will flash if you're applying too much pressure while brushing.
4. Quadpacer notification: Some models have a light that will briefly flash in 30 second intervals to inform you that you need to move to the next quadrant of your mouth.
5. Trouble/Issues: If your Sonicare toothbrush is blinking a light at the top of the handle, this might indicate a problem with the toothbrush. If the light keeps blinking even after you've charged your toothbrush and changed the brush head, you should contact Philips customer service.
Remember each model might vary, so it's always best to refer to the specific user manual of your model for accurate information.
