Heart Rate Sensor
Speed + Distance Sensor
Watches are for more than keeping time. Digital technology gives
your watch the ability to display your heart rate or measure your
speed and distance traveled. These functions require the use of
external sensors that transmit information wirelessly to your
watch. This booklet provides instructions for properly setting up,
operating and maintaining these devices. Look for the section that
is appropriate for the type of device you have.
For information on using your watch, consult
the watch instruction booklet.
