Operation Manual

Settings for Running

Before you start an activity you can choose a training program and also decide what information you

would like to see as you train.

There are a wide range of metrics that you can choose to see while running including calories, heart

rate, heart rate zone and distance.

Choosing other metrics to display

Note: To get help on choosing which metrics you want to see during an activity, see Choosing

which metrics to display.

To choose to see just one metric for speed, average speed, pace or average pace, press DOWN to

the SETTINGS menu. Select METRICS, then press RIGHT. Select SPEED, AVG SPEED, PACE or AVG

PACE.

To choose to see speed, pace or both metrics, press DOWN to the SETTINGS menu. Select METRICS

then press RIGHT. Select SPEED, then press RIGHT. Select SPEED, PACE or BOTH.

Settings for Outdoor Cycling

You can log your heart rate, speed and location using the integrated sensors when cycling.

If you want to review your performance while cycling, in the interest of your own safety it is best to

mount the GPS watch using the optional bike mount so that you can keep both hands on the handle

bars.

If you want to review your heart rate while cycling, we recommend connecting an optional external

heart rate sensor so that you can review your heart rate safely.

Setting the wheel size for use with a Cadence & Speed Sensor

If you are using a Cadence and Speed Sensor, you should set the WHEEL SIZE setting to increase the

accuracy of the metrics provided by the sensor. This setting is the circumference of your rear tyre

in millimetres (mm).

To set your wheel size, do the following:

1. From the activity start screen, press DOWN to open the SETTINGS menu.

2. Select WHEEL SIZE, then press RIGHT.

3. Set the size so it's correct for your rear wheel.

To find the circumference of your rear wheel, you can either measure the wheel yourself using a

tape measure, or look up the value in an online calculator. For example, on this site you can find

the circumference using the diameter of the wheel and the thickness of the tyre:

For example, if your wheel size is 700c and the tyres are 25 mm thick, the circumference is 2111

mm. This is the value you should enter.

which metrics to display.

Settings for Swimming

Note: TomTom GPS watches are water-resistant. You can swim with these watches. However, the

built-in Heart Rate Monitor does not work under water.

Before you start a swimming activity, you should check the POOL SIZE setting for the pool where

you are swimming. This setting is the length of the pool in metres or yards.
