D. Satellite Status Page
The strength of the satellite signal reception is displayed at the bottom right hand corner
of the screen (when the status notification page is not active). If the color of the satellite
icon signal is not green, it means the unit is still under positioning. When the signal icon
is in green, it indicates that the unit has completed the positioning process and is ready
for navigation.
Swipe up the notification page; select
status of signal reception. The user will also see additional information such as current
altitude and estimation discrepancy to determine the status of the unit's positioning.
