Broadcasting Heart Rate Data During an Activity

You can set up your D2 Charlie device to broadcast your heart
rate data automatically when you begin an activity. For example,
you can broadcast your heart rate data to an Edge
cycling, or to a VIRB
®
action camera during an activity.
NOTE: Broadcasting heart rate data decreases battery life.
1
From the heart rate widget, hold UP.
2
Select Options > Broadcast During Activity.
3
Begin an activity
(Starting an Activity, page
The D2 Charlie device starts broadcasting your heart rate
data in the background.
NOTE: There is no indication that the device is broadcasting
your heart rate data during an activity.
4
If necessary, pair your D2 Charlie device with your Garmin
ANT+ compatible device.
NOTE: The pairing instructions differ for each Garmin
compatible device. See your owner's manual.
TIP: To stop broadcasting your heart rate data, stop the
activity

Setting an Abnormal Heart Rate Alert

You can set the device to alert you when your heart rate
exceeds a certain number of beats per minute (bpm) after a
period of inactivity.
1
From the heart rate widget, hold UP.
2
Select Options > Abnormal HR Alert > Status > On.
3
Select Alert Threshold.
4
Select a heart rate threshold value.
Each time you exceed the threshold value, a message appears
and the device vibrates.

Turning Off the Wrist-based Heart Rate Monitor

The default value for the Wrist Heart Rate setting is Auto. The
device automatically uses the wrist-based heart rate monitor
unless you pair an ANT+ heart rate monitor to the device.
1
From the heart rate widget, hold UP.
2
Select Options > Status > Off.

Putting On the Heart Rate Monitor

You should wear the heart rate monitor directly on your skin, just
below your sternum. It should be snug enough to stay in place
during your activity.
1
If necessary, attach the strap extender to the heart rate
monitor.
2
Wet the electrodes
on the back of the heart rate monitor to
create a strong connection between your chest and the
transmitter.
3
Wear the heart rate monitor with the Garmin logo facing right-
side up.

NOTE: Make sure the care tag does not fold over.
After you put on the heart rate monitor, it is active and sending
data.

Tips for Erratic Heart Rate Data

If the heart rate data is erratic or does not appear, you can try
these tips.
• Reapply water to the electrodes and contact patches (if
applicable).
• Tighten the strap on your chest.
• Warm up for 5 to 10 minutes.
• Follow the care instructions
Monitor, page
11).
• Wear a cotton shirt or thoroughly wet both sides of the strap.
Synthetic fabrics that rub or flap against the heart rate
monitor can create static electricity that interferes with heart
rate signals.
• Move away from sources that can interfere with your heart
rate monitor.
Sources of interference may include strong electromagnetic
fields, some 2.4 GHz wireless sensors, high-voltage power
lines, electric motors, ovens, microwave ovens, 2.4 GHz
cordless phones, and wireless LAN access points.

Caring for the Heart Rate Monitor

A buildup of sweat and salt on the strap can decrease the ability
of the heart rate monitor to report accurate data.
• Rinse the heart rate monitor after every use.
• Hand wash the heart rate monitor after every seven uses or
one pool swim, using a tiny amount of mild detergent, such
as dishwashing liquid.
NOTE: Using too much detergent may damage the heart rate
monitor.
• Do not put the heart rate monitor in a washing machine or
dryer.
• When drying the heart rate monitor, hang it up or lay it flat.

Running Dynamics

You can use your compatible D2 device paired with the
HRM-Run
accessory or other running dynamics accessory to
provide real-time feedback about your running form. If your D2
device was packaged with the HRM-Run accessory, the devices
are already paired.
The running dynamics accessory has an accelerometer that
measures torso movement in order to calculate six running
metrics.
Cadence: Cadence is the number of steps per minute. It
displays the total steps (right and left combined).
Vertical oscillation: Vertical oscillation is your bounce while
running. It displays the vertical motion of your torso,
measured in centimeters.
Ground contact time: Ground contact time is the amount of
time in each step that you spend on the ground while
running. It is measured in milliseconds.
NOTE: Ground contact time and balance are not available
while walking.
Ground contact time balance: Ground contact time balance
displays the left/right balance of your ground contact time
connection should be on your right
