Initial Chartplotter Settings
The first time you turn on the chartplotter, you must configure a series of initial settings. These settings must
also be configured when restoring original factory settings ( page 119 ). Each of these settings can be updated
later. Follow the on-screen directions.
Note: To calibrate the water speed, you must have a speed-capable transducer connected to a GSD
™ 22 or a
NMEA 0183-capable water-speed sensor.
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 flashing
question mark appears on the boat icon on the chart screen.
