WEARING YOUR OH1
WHEN MEASURING HEART RATE FROM YOUR FOREARM OR UPPER ARM
To measure heart rate accurately, you need to wear the OH1 snugly on your forearm or upper arm, not on
your wrist.
1. Place the sensor into the armband holder with the lens facing up.
2. Wear the armband so that the sensor is on the underside of the armband firmly against your skin.
3. Wear the OH1 around your forearm or upper arm.
The sensor must be in firm skin contact, but not too tight to prevent blood flow. For most accurate heart
rate measurement, we advise you to wear your OH1 for a few minutes prior to starting the heart rate
measurement.
WHEN MEASURING HEART RATE FROM YOUR TEMPLE IN SWIMMING
The OH1 set has been available with two different types of swimming goggle clips. Your set can include
two clips (picture A) or one clip (picture B). Both types of clips are well suited to be worn when swimming,
their design is just slightly different. If your set included two clips (picture A), try both to see which one fits
your swimming goggles better and keeps the sensor securely in place on your temple.
