Please help me figure out how to reset it. It is not even a year old.
Try these - I found them on support somewhere but don't have the link any more:
Forerunner 210 If for any reason you feel as if your Forerunner 110, 210, or 610 needs to be reset, use the steps outlined below. Only use this reset sequence sparingly and only when needed. The device being locked up or you would like to reset to factory default settings would be reasons to perform the reset
.To reset your Forerunner:
Power the device Off (Press and hold the light button) Press Light and Lap/Reset to power the device on Select Yes on the Clear User Data? message Press the Page/Menu button to select ok and to confirm the reset The watch will shut off and power back on Proceed through the initial setup The Forerunner 110, 210, or 610 is now reset.
NOTE: Resetting the Forerunner in this manner will only erase your User Profile. This reset will not erase the History or GPS data in the device. There are a few instances in which you may want to perform a Master Reset on your Forerunner 110, 210, and 610, such as:
not receiving a satellite signal want to restore the factory default settings not functioning properly By doing this reset, all user information, workout history, and satellite data will be erased. You will want to backup all information to the computer before doing the reset.
Power off the watch (press and hold Light, say Yes to prompt) Press and hold Start/Stop and Lap/Reset Once the two buttons from step 2 are pressed in, press and hold Light (You should now be holding down all three buttons) After the first beep, release Start/Stop After the second beep, release Lap/Reset Release Light. The device is now reset. You will want to leave the device outside with a clear view of the sky for a minimum of 20 minutes to acquire satellite data.
