Acquiring Satellite
Signals
Before you begin using the
Forerunner, you must acquire
GPS satellite signals. To acquire
satellite signals, go outdoors
away from tall buildings and
trees. Acquiring satellite signals
may take 30–60 seconds.
To acquire satellites:
Go outdoors to an open area and
press the Power
button to turn
on the Forerunner.
Wait while the Forerunner
searches for satellites. For best
reception, make sure the GPS
antenna is facing up. Stand still
in an open area, and do not
begin walking or running until
the Locating Satellites page
disappears.
GPS antenna is
located here.
After the Locating Satellites page
disappears, you can begin your
run or other activity.
To turn off GPS and use the
Forerunner indoors, see page 44.
