Place the AirFloss handle into the Fill & Charge station cup, with the AirFloss reservoir door facing toward the middle of the Fill & Charge station. The Philips Sonicare logo should be facing out (towards you).
Make sure the handle is touching the bottom of the charger.
If the handle is fully in contact with the charger, you will NOT see the curved line facing down (under the Sonicare logo) while it’s in the charger.
If you can see this curved line, simple press the handle down into the charger to ensure it’s fully inserted and connected to the charger..
Please note that if your AirFloss is not charging, it is still running and will lose power. This is why its important to keep your AirFloss engaged on the charger when not in use.
