Restart the Solar and the application if necessary. *** **No sound is emitted** * Check the volume level by briefly pressing the button. *** **The variometer seems inaccurate** * Check that the Solar is correctly positioned in an area sheltered from relative wind. * Avoid positions directly exposed to airflow or subject to rapid movements. * Resetting the instrument may also improve operation. *** **The flight is not recorded** \ Check that: * the Solar is connected to the Syride Link application, * the application is active, * the phone’s GPS is enabled, * the phone has proper GPS reception. Without connection to the application, no flight can be recorded. *** **The Solar is not charging** * Check the USB-C cable and the power source. * The orange LED should show a variation in intensity indicating that charging is in progress. * Solar charging depends on lighting conditions and may be slower. *** **The issue persists** * Perform a simple reset or a factory reset via Syride Link. * If the problem persists, contact Syride support. --- # 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/12-troubleshooting.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.
