Setup, Compatibility & Care
To set up your device, fully charge the handle using the provided glass base. Before the first use, download the Sonicare app and pair your toothbrush via Bluetooth to ensure your firmware is up to date and your brushing data is tracked. To care for your DiamondClean 8500, rinse the brush head thoroughly after each use and wipe the handle with a damp cloth. Store the handle in the charging case or upright in the glass base to keep it dry. Ensure you replace your A3 brush head every three months, or sooner if the bristles appear frayed, to maintain optimal cleaning efficacy.
