amount of mild detergent, such as dishwash-
ing liquid.
NOTE: Using too much detergent may dam-
age the heart rate monitor.
• Do not put the heart rate monitor in a wash-
ing machine or dryer.
• When drying the heart rate monitor, hang it
up or lay it flat.
Data Storage
The heart rate monitor can store up to 20 hours
of data in a single activity. When the heart
rate monitor memory is full, your oldest data is
overwritten.
You can start a timed activity on your paired
Forerunner device, and the heart rate monitor
records your heart rate data even if you move
away from your device. For example, you can
record heart rate data during fitness activities
or team sports where watches cannot be worn.
Your heart rate monitor automatically sends
your stored heart rate data to your Forerunner
device when you save your activity. Your heart
rate monitor must be active and within range (3
m) of the device while data is uploaded.
