Pioneer AVIC-S2 RU - Manual (Page 24)

4.2.2 GPS connection indicator
In the middle to the left there is a lamp similar to the ones used for switches. This
one has more colours and represents more values:
• a fast blinking green lamp means that there is communication with the GPS
and data is being received,
• other colours may not appear with a built-in GPS. Should any of
these appear, this means a faulty operation of your device.
4.2.3 GPS data quality indicator
In the top left corner there is a satellite dish to show the quality of the GPS position.
Different colours represent different signal quality:
• black with a red cross means there is no connection with the GPS device.
• red means the GPS is connected but no GPS position is available,
• yellow means 2D reception. A GPS position has been acquired, AVIC-S2 is
ready for navigation, but the GPS is using enough satellites for calculating the
horizontal position only. Elevation data is not provided, and the position error may
be significant.
• green means 3D reception. The GPS receiver has enough satellites to
calculate altitude. Position is generally correct (yet it can still be inaccurate due to
different environmental factors). AVIC-S2 is ready for navigation.
4.2.4 Time synchronization
In the top right corner of the screen you have another button that leads to a new
screen where you can synchronize the clock of your AVIC-S2 to the very accurate
time provided by the connected GPS.
