to use your Forerunner safely and 

responsibly.

Clean the Forerunner and 

the heart rate monitor using 

a cloth dampened with a mild 

detergent solution. Wipe dry. 

Avoid chemical cleaners and 

solvents that may damage plastic 

components.
Do not store the Forerunner 

where prolonged exposure to 

temperature extremes may occur 

(such as in the trunk of a car), as 

permanent damage may result. 

User information, such as history, 

locations, and tracks, is retained 

indefinitely in the unit’s memory 

without the need for external 

power. Back up important user 

data by downloading it to Garmin
