About sensors

Sensors are external devices which you can link to your watch to provide information about your
activity. Two types of sensors can be used with your watch:

Heart rate monitor - this measures your heart rate as you train. The TomTom Heart Rate Monitor
is included in some products and available as an accessory for others.

Cadence sensor - this measures your cadence as you cycle. The TomTom Cadence Sensor is
included in some products and available as an accessory for others. TomTom Runner does not
support the Cadence Sensor.
Cadence
Cadence measures the speed at which you pedal in revolutions per minute (rpm). In a low gear, you
may have a very high cadence but a lower speed. In a high gear, you may have a low cadence but a
higher speed. Cyclists train to find the balance between cadence and speed which allows them to
cycle as efficiently as possible.

Heart Rate Monitor

To use the TomTom Heart Rate Monitor with your watch, do the following:
1. Attach the monitor to the strap.
2. Attach the strap around your chest, so the monitor sits just above the base of your chest bone.
Make sure the monitor is the right way up so that the word 'TomTom' is the right way up for
someone standing in front of you.
Tip: Wet the contact areas on the inside of the strap before placing it around your chest. This
makes it easier for the monitor to pick up your heartbeat.
3. From the clock screen on your watch, move down.
4. Select Sensors then move right.
