The stopwatch can be operated only from the Stopwatch
main screen. While the stopwatch is running, “STW” will
flash in all main screens except the Stopwatch main screen.
Time in Zone
The Time in Zone screen records the amount of time spent
exercising within the preset target zone. Timing begins
automatically during a workout when the heart rate falls
between the chosen preset target zone upper and lower
limit values.
Note: Time in Zone data accumulates only while the
stopwatch is running. If the stopwatch is not started at the
beginning of the workout, no data will be recorded in the
Time in Zone screen.
You can view accumulated time in zone at any point during
or after your workout by advancing to the Time in Zone
main screen using the Mode button. “TIZ” and time in tar-
get zone will appear in the lower row of the display (see
Figure 7).
