10) Meaning of LED indicators and audio signals

The Solar uses an LED and audio signals to indicate its operating status, battery level and various operations.

---

Blue LED — operation and Bluetooth

The blue LED indicates the operating status of the instrument and the Bluetooth connection.

• single blue LED blink: waiting for Bluetooth connection

• fast double blue LED blink: connected to a Bluetooth application

---

Orange LED — charging status

The orange LED indicates the battery charging status when the Solar is connected to a USB power source.

• orange LED with slowly varying intensity (wave effect): battery charging in progress

• steady blue LED: battery fully charged

Solar charging operates automatically in the presence of light and does not trigger the orange LED.

Startup audio signal

When turning on, the Solar emits a melody indicating that the instrument is ready to operate.

A series of beeps then indicates the battery level:

• 3 beeps: high battery level

• 2 beeps: medium battery level

• 1 beep: low battery

If the battery is too low, the instrument will not start.

Variometer audio signal

In flight, the Solar emits audio signals corresponding to your vertical speed:

• high-pitched sounds: climb,

• low-pitched sounds: descent,

• no sound: stable air.

The volume can be adjusted using the button or via Syride Link.

Zeroing audio signal

When the zeroing function is enabled, a specific audio signal is emitted when the air mass is close to neutral. This signal is only activated during flight.

Shutdown audio signal

When turning off, a melody confirms that the instrument has shut down correctly.
