Tips for Erratic Heart Rate Data
If the heart rate data is erratic or does not appear, you can try 
these tips.
• Clean and dry your arm before putting on the device.
• Avoid wearing sunscreen, lotion, and insect repellent under 
the device.
• Avoid scratching the heart rate sensor on the back of the 
device.
• Wear the device above your wrist bone. The device should 
be snug but comfortable.
• Wait until the   icon is solid before starting your activity.
• Warm up for 5 to 10 minutes and get a heart rate reading 
before starting your activity.
NOTE: In cold environments, warm up indoors.
• Rinse the device with fresh water after each workout.
• While exercising, use a silicone band.
Viewing the Heart Rate Widget
The widget displays your current heart rate in beats per minute 
(bpm) and a graph of your heart rate for the last 4 hours.
1
From the watch face, select DOWN.
2
Select   to view your average resting heart rate values for 
the last 7 days.
Broadcasting Heart Rate Data to Garmin Devices
You can broadcast your heart rate data from your tactix Charlie 
device and view it on paired Garmin devices.
NOTE: Broadcasting heart rate data decreases battery life.
1
From the heart rate widget, hold MENU.
2
Select Options > Broadcast Heart Rate.
The tactix Charlie device starts broadcasting your heart rate 
data, and   appears.
NOTE: You can view only the heart rate widget while 
broadcasting heart rate data from the heart rate widget.
3
Pair your tactix 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, select any 
key, and select Yes.
Broadcasting Heart Rate Data During an Activity
You can set up your tactix 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
®
device while 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 MENU.
2
Select Options > Broadcast During Activity.
3
Begin an activity (Starting an Activity, page 3).
The tactix 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 tactix 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 (Stopping an Activity, page 3).
Turning Off the Wrist 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 MENU.
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 
À
 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.
The loop 
Á
 and hook 
Â
 connection should be on your right 
side.
4
Wrap the heart rate monitor around your chest, and connect 
the strap hook to the loop.
NOTE: Make sure the care tag does not fold over.
After you put on the heart rate monitor, it is active and sending 
data.
