To start using the Suunto Smart Sensor and heart rate belt:
The belt turns on automatically when it detects a heart beat.
Wear the belt against your bare skin for best results.
Suunto Smart Sensor can also be used with Movesense compatible sports clothing, such as the Movesense t-shirt and sports bra from Salomon. Simply, moisten the electrode areas on the apparel and snap the sensor snugly into the apparel connector.
