# 12) Troubleshooting

This section helps you resolve the most common issues that may occur when using the Solar.

***

**The Solar does not turn on**

* Check that the battery is sufficiently charged.
* Recharge the instrument using a USB-C cable or expose it to light to activate solar charging.
* If the instrument still does not turn on, perform a simple reset by pressing and holding the power button for 30 seconds.

***

**The Solar does not connect to the application**

\
Check that:

* the Solar is turned on,
* Bluetooth is enabled on your phone,
* the application is open,
* the Solar is selected in the application’s Bluetooth sensors.

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.
