Suunto t3 User Manual page 31

While training, the stopwatch displays either the real-time Training Effect or heart rate in the center
of the screen. You can switch between the two by long pressing the BACK button.
The information that is displayed while the stopwatch is running depends on the device's settings
as well as on whether there is a speed and distance POD connected. The default shortcut, which
appears on the bottom row of the display, is the Training Effect target. However, if you have set
an interval or warm-up timer on, lap time is the default shortcut and is shown as a countdown time
of the current interval. Short pressing the BACK button switches between shortcuts.
Pressing the BACK button
changes the shortcut at the
bottom of the display. Some
shortcuts are only
available when connected
to speed and distance POD.
When the stopwatch has been stopped, you can reset it by long pressing the UP button, as shown
in the figure below.
Pressing the UP button, when
the stopwatch is running, stores
the split time and displays it in
the top row of the Suunto t3. It
also displays the average heart
rate and shows the lap time.
After 3 seconds, the display
jumps back to the stopwatch.
This number
indicates the
ongoing lap.
