Problem Solution/Answer
The bezel is not
responding to my
taps.
Unlock the bezel: press enter and quit simultaneously.
Press rmly on the bezel for the best results. Tap the
outer ring on the bezel, not the inner ring near the watch
face. Adjust the sensitivity setting (see page 30).
My Forerunner
never gets satellite
signals.
Touch and hold GPS. Make sure GPS is set to On.
Take your Forerunner outside and away from tall
buildings. Remain stationary for several minutes.
The battery gauge
does not seem
accurate.
Allow the Forerunner to fully discharge, and then fully
charge it (without interrupting the charge cycle).
The heart rate
monitor, foot pod, or
GSC 10 will not pair
with the Forerunner.
Stay 10 m away from other ANT+ accessories while
pairing. Bring the Forerunner within range (3 m) of the
sensor while pairing. Restart the scan for the accessory
(see page 33). Make sure the accessory is sending data
(for example, you need to be wearing the heart rate
monitor). If the problem persists, replace the battery in
the accessory.
The heart rate data
is inaccurate.
See page 34.
The heart rate
monitor strap is too
big.
A smaller elastic strap is sold separately. Go to
