Just came back from a speed run. Trying to change my running style and also increasing
my speed. I hooked my Garmin watch which is the forerunner 110 and the display was
blank I had to reset the watch and I had trouble remembering how to do so and I found this.
How do I reset my Forerunner 110, 210 and 610?
There are a few instances in which you may want to reset the Forerunner 110, 210 or 610, including the following:
Not receiving a satellite signal
Restore the device to factory default settings
Not functioning properly
To reset* the Forerunner:
Power device off (press and hold Light, say Yes to prompt)
Press and hold Lap/Reset
Press Light to power device back on while still holding Lap/Reset
Select Yes on Clear User Data? message
Select OK and confirm reset
The watch will shut off and power back on. Proceed through the initial setup to complete the reset process.
NOTE: This reset will only erase the User Profile, and not erase History or GPS data. If this reset does not correct the issue, refer to FAQ article “How do I master reset my Forerunner 110, 210 and 610?” for further direction.
