Try double tapping differently.
- Try holding Swarovski Activity Crystal up against your skin when you double tap it. It's easier to double tap the device against soft surfaces. Another helpful tip for Swarovski Activity Crystal is to tap at the 6 o'clock position.
Is your device running out of battery?
- Is the battery correctly oriented? The negative terminal should be visible (it is the side without writing on it).
- Try a new battery as well. Swarovski Activity Crystal runs on coin-cell battery CR2032. We recommend well known brands like Panasonic or Energizer. You can find the battery replacement instructions here.
