About GPS Satellite Signals
Your zūmo must acquire GPS (Global
Positioning System) satellite signals
to operate. If you are indoors, near tall
buildings or trees, or in a parking garage,
your zūmo cannot acquire satellites.
Go outside to an area free from tall
obstructions to use your zūmo.
When your zūmo has acquired satellite
signals, the signal strength bars on the
Menu page are green
. When it
loses satellite signals, the bars turn red or
disappear
.
