The Wrist setting for the wrist you wear your watch on.
As you swim, your watch registers your strokes and the number of turns you make in the pool. To
calculate the distance you have swum and your speed, your watch uses the pool size and the number
of turns you have made. If the pool size is not accurate, the metrics for your swimming activity cannot
be worked out correctly. Your watch needs to know which wrist you wear your watch on so it can
register your strokes.
To change the Pool size and Wrist settings, do the following:
1. From the activity start screen, move down to open the Settings menu.
2. Select Pool size, then move right.
3. Set the size so it shows the correct length for the pool.
4. Move left to go back to the Settings menu.
5. Select Wrist, then move right.
6. Change the setting to the wrist you wear your watch, if necessary.
7. Move right to go immediately back to the activity screen.
When you select Swim, your watch does not use its internal GPS receiver.
To set other metrics, such as strokes, do the following:
1. From the activity start screen, move down to the Settings menu.
2. Select Display, then move right.
3. Select Left or Right to set the metric shown on the left or the right.
4. Select the metric to be displayed from the list, such as Strokes or Lengths.
Settings for Treadmill activities
Your height is set on the very first use of your watch. Before you start an activity on the treadmill for
the first time, you should check that your height has been set correctly. You can do this in your
TomTom MySports account or on your watch.
As you run on a treadmill, your watch registers the number of times you swing your arm back and
forward and how quickly. This matches the number of strides you make as you run. Your watch uses
your height to calculate the length of your stride, and from this the distance you have run and your
pace.
To check your height on your watch, do the following:
1. From the clock, move down to open the Settings menu.
2. Select Profile, then move right.
3. Select Height, then move right.
4. Set your height.
Calibrating your watch for Treadmill activities
The distance measurements your watch makes for Treadmill activities are less accurate than for Run
activities. When you run outdoors, your watch uses GPS to measure the distance you cover.
If you calibrate your watch, the distance measurements for Treadmill activities become more accurate.
To calibrate your watch, do the following:
1. During your first Treadmill activity, run for a short time such as 1 m or 1km, then pause your watch
and the treadmill.
To pause your watch, move left during the activity.
2. On your watch, move down to open the Settings menu.
3. Select Calibrate then move right.
4. Change the distance to 1m or 1km to match the distance shown on the treadmill.
5. Move right to go immediately back to the activity screen.
