The sounder will now begin searching for the appropriate satellites for your present
position and should acquire a fix in approximately one minute. While the receiver
searches for satellites, a flashing satellite symbol will appear at the left-hand side of the
status bar located at the bottom of the screen. The status bar is used to monitor satel-
lite signal reception and activated alarms, it also shows the digital depth on a
continual basis.
A signal strength bar for each satellite in view will appear on the lower half of the
page, with the appropriate satellite number under each bar. The progress of satellite
acquisition is shown in three stages:
• No signal strength bars: The receiver is looking for satellites.
• Hollow signal strength bars: The receiver has found satellites and is collecting data.
• Solid signal strength bars: The receiver has collected the necessary satellite data and
the sounder is ready to use.
Once the receiver has collected information from at least three satellites, the satellite
symbol on the status bar will stop flashing.
