### Logitech Solar App: A Quick Primer

- Top Gauge (): Here's where you'll see a lux (or light intensity) meter, so you'll always know how much solar power your keyboard is getting. We recommend approximately 100 lux during the daylight hours. Tip: Move the keyboard around your room to see how the light intensity varies. The higher the intensity, the more power your solar keyboard will get.
- Middle Gauge (): Here's where you'll see how much energy your keyboard currently has. You'll see two views: Percentage and History. The Percentage view tells you exactly how much energy your keyboard has now, and the History view shows your energy reserve level during previous weeks.
- Bottom Status (): Here's where you'll see the current energy reserve status. Make sure to click on the link at the end of the text to learn more about what to do if your energy reserve is low. Note: Status is updated several days after any significant light intensity (lux level) change.
