Altitude settings
Smoothing: Smoothing is useful if you feel that the displayed
altitude value appears to be too erratic. Smoothing applies an
averaging filter and may cause the displayed altitude value to
respond more slowly to changes. You can turn altitude smoothing
off or on.
Update Ascent Rate: Set the Watch to update the period at which
the ascent rate is calculated. You can choose intervals of 30
seconds, or 1, 10, 30, or 60 minutes. Set this feature shorter for
faster vertical activities such as skiing or longer for slower vertical
activities such as climbing.
Hands-Free settings
In addition to Auto Split, you can use the Watch to set other
hands-free settings when used in conjunction with the GPS-3D
Sensor. Even when enabled, you can still start and stop the
chronograph manually without affecting the hands-free operation.
Auto Start: This feature enables the chronograph to start when
you start moving. It may take a few seconds for the GPS-3D
Sensor to detect movement, causing a slight delay in start time.
Auto Stop: This feature enables the chronograph to stop when you
stop moving. It may take a few seconds for the GPS-3D Sensor to
detect that you have stopped moving, causing a slight delay in stop
time.
Auto Split: This feature enables the chronograph to take splits
automatically according to the distance traveled. For example, if
Unit settings: Unit settings allow you to determine distance (for
example miles versus kilometers) and heart rate (beats versus
percentage) display units.
S+D settings
Configure the following speed and distance settings:
Zone Type: Similar in concept to a heart rate target zone alert,
you can set the Watch to track your speed or your pace and to alert
you if you move too slowly or too quickly (alert types include an
audible alert that beeps or a silent alert that flashes). You can set
speed and pace limits independently. For instance, set pace limits
to control pace for your run and set speed limits to values useful
for cycling. Then simply switch between the settings for each
activity.
Distance Alert: Set the Watch to alert you for distance intervals.
For example, you can set the Watch to alert you for every mile you
travel. The distance alert will only function when you run the
chronograph. If you would like the Watch to take a split based on
distance traveled, refer to the Hands-Free Settings on page 55.

Speed Smoothing: Turn speed smoothing off or on.
Pace Smoothing: Turn pace smoothing off or on.
