2.1. Optical heart rate

Optical heart rate measurement from the wrist is an easy and convenient way to track your
heart rate. To get the best results, please keep in mind factors that may affect heart rate
measurement:
The watch must be worn directly against your skin. No clothing, however thin, can be
between the sensor and your skin.
The watch may need to be higher on your arm than where watches are normally worn.
The sensor reads blood flow through tissue. The more tissue it can read, the better.
Arm movements and flexing muscles, such as gripping a tennis racket, can change the
accuracy of the sensor readings.
When your heart rate is low, the sensor may not be able to provide stable readings. A
short warm up of a few minutes before you start the recording helps.
Dark skin and tattoos block light and prevent reliable readings from the optical sensor.
The optical sensor may not provide accurate heart rate readings for swimming activities.
For highest accuracy and quickest responses to changes in your heart rate, we
recommend using a compatible chest heart rate sensor such as Suunto Smart Sensor.
WARNING: Optical heart rate sensor technology is currently not as accurate or reliable
as measuring heart rate from the chest. Your actual heart rate may be higher or lower that
the optical sensor reading.
