charging or connecting to a personal computer.
To charge the Forerunner:
1.  Snap the Forerunner into the 
charging cradle.
2.  Plug the small end of the AC 
adapter into the mini-USB port 
on the cradle. Plug the other end 
into a standard wall outlet.
NOTE: The Forerunner will not charge outside the temperature range of 
0°C–50°C (32°F–122°F).
You can also charge the Forerunner by connecting it to your personal 
computer with the enclosed USB cable. However, you must install
