Suunto Spark User Guide
Pairing
Before you use your Suunto Spark for the first time, you need to pair it with a compatible device.

Place the earbuds in the charging case.
Press and hold the button on the case for 2 seconds, until the LED light flashes white.
On your device, select Suunto Spark from the Bluetooth list to connect.
Pairing is complete when the LED light stops flashing.
