Getting Started
Initial Chartplotter Settings
The rst time you turn on the chartplotter, you must congure a series of initial settings. You must also
congure these settings when restoring original factory settings (page 86). You can update each of these
settings later. Follow the on-screen directions to congure the initial settings.
GPS Satellite Signal Acquisition
When you turn on the chartplotter, the GPS receiver must collect satellite data and establish the current
location. When the chartplotter acquires satellite signals, the signal strength bars at the top of the Home screen
are green . When the chartplotter loses satellite signals, the green bars disappear and a ashing
question mark appears on the vehicle (boat) icon on the chart screen.
