Wearing the device

When wearing the product, make sure it does not touch the bone on your wrist. Wear the product closely around your wrist. Tighten the wrist band if your pulse (heart rate) is not measured correctly. However do not wear the product too tight. If you feel any discomfort, loosen the wristband.

Sensor (reads your pulse on the back of your wrist)

Note:

❏ After putting the device on, press the A button on the Time screen, and check that your pulse is being measured. Your

pulse (heart rate) should be displayed within about 30 seconds. If it is not displayed, readjust the position of the device (see above illustration), or tighten the wrist band.

❏ The device may not be able to measure accurately if it is not in contact with your skin or if it moves around too much

while exercising. Try tightening the wrist band by one hole.

Important:

The accuracy of the heart rate sensor is affected by cold body or ambient temperature. Protect the device by wearing it under a sleeve in cold or windy conditions. A warning (see below illustration) will trigger if the device temperature will drop too low.
