How do I charge my Next-Generation Sonicare DiamondClean 8000-9900 using the travel case?

Plug the charging cable into the travel case and into a power supply unit.

Place the toothbrush in the travel case.

The battery status will appear on the display with a charging icon while the toothbrush emits two beeps to indicate that charging has started.

Leave the toothbrush in the travel case until fully charged. The display will turn off when the toothbrush has finished charging.

Note: Make sure that the travel case is placed on its side for better stability.

Note: Not all models include a charging travel case.
