Acquiring GPS Satellite Signals
The device may need a clear view of the sky to acquire satellite signals. The time and date are set automatically based on the GPS position.
When the device acquires satellite signals, 
appears at the top of the Home screen.
If the device loses satellite signals, disappears and a flashing question mark appears over 
on the chart.
