How do I know the UV light is working?

You can verify UV operation safely:

  1. With the base plugged in, remove your toothbrush handle from the base, pick up the base, turn it over, and press the small white button under the bottom (It looks like a foot on the base and has clear rubber over it - see image below)
  2. While pressing the small white button, insert the handle
  3. Look at the bottom of the base—you should see the UV ring glow
⚠️ Safety: Never stare directly into UV light.
