Under normal outdoor use conditions, this charging significantly extends battery life and reduces the frequency of USB recharging. For optimal efficiency, position the Solar so that its solar panel is exposed to light during flight or during storage. Solar charging works even when the instrument is turned off. *** **USB charging** \ The Solar can be recharged using a USB-C cable, by connecting it to a computer or a standard USB charger. The orange LED indicates the charging status: * **orange LED with slowly varying intensity (wave effect)**: battery charging in progress * **steady blue LED**: battery fully charged A full charge takes approximately 1 hour. *** **Battery life** \ Battery life depends on usage (volume, sink alarm active or not), Bluetooth connection and exposure to light. Thanks to the integrated solar charging, battery life (≈50h) can be significantly extended under normal usage conditions. *** **Recommendations** \ To preserve battery lifespan: * avoid leaving the instrument exposed to extreme temperatures (for example under a car windshield in direct sunlight), * recharge it at least once a year via USB if you do not use it for a long period, --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://manuals.syride.com/solar-english-manual/3-charging-the-solar.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
