You can switch to any other mode, such as TIME OF DAY, while the
CHRONO Mode is running. A stopwatch flag indicates that CHRONO Mode
is running in the background.
Chronograph Display Options
If you are not using a heart rate sensor, the watch displays both lap and
split times (after you have taken your first split). To select which time is
displayed in the lower display line, press and release STOP/RESET/SET
when the Chronograph is reset (00.00.00) but before you begin timing laps.
If you are using the heart rate sensor, the watch displays heart rate
information in addition to the Chronograph time. You may choose to view
either lap or split time as well as heart rate data. For heart rate data display
options, see pages 8–9 and Figure 2.1, on formatting the display when the
HRM is active.
Using the Chronograph
1. Press MODE until CHRONO appears.
2. Press START/SPLIT to begin timing.
3. Press START/SPLIT while CHRONO Mode is running to take a lap/split.
This stores the current lap and split data and starts a new lap. The watch
briefly shows the lap and split times you just recorded as well as the lap
number. If you are viewing HRM data, the watch next displays heart rate
information for the lap.

CHRONO Mode (30-Lap Model only)
The CHRONO Mode is the main “workout” mode in your watch. It provides
a stopwatch for recording the elapsed time for 30 readings, such as a lap,
in a single event, as well as other information for an entire event up to 100
hours in duration. Data for up to 30 readings may be stored including the
lap number, the individual lap time and the total elapsed split time.
When the heart rate sensor is active, CHRONO Mode tracks three pieces of
statistical data:
• The amount of time your heart rate is within the target zone while
CHRONO Mode is running
• The average heart rate for the period that the HRM system was active
and CHRONO Mode is running
• The peak and minimum heart rate for the period that the HRM system
was active and CHRONO Mode is running
Data accumulation stops if you stop the Chronograph while the HRM
system is active and resumes when you restart the Chronograph. If the
Chronograph is allowed to run out while the HRM system is running, the
HRM shuts off automatically and data accumulation ceases.
NOTE: Throughout this section we will talk about “laps” and
“splits.” “Lap time” is the time for each segment (lap) of an event.
“Split time” is the total elapsed time since the start of the event.
