GPS Signal Strength
The Satellite Status Page can be helpful in
troubleshooting weak (or missing) signal levels due to poor
satellite coverage or installation problems. Refer to this
page occasionally to monitor GPS receiver performance
and establish a normal pattern for system operation.
Should problems occur at a later date, it may be helpful to
have an established baseline from which to compare.

MULTI FUNCTION DISPLAY
As the GPS receiver locks onto satellites, a signal
strength bar is displayed for each satellite in view, with
the appropriate satellite number (01-32) underneath each
bar. The progress of satellite acquisition is shown in three
stages:
• No signal strength bars - the receiver is looking
for the satellites indicated.
• Hollow signal strength bars - the receiver has
found the satellites and is collecting data.
• Solid signal strength bars - the receiver has
collected the necessary data and the satellites are
ready for use.
• Checkered signal strength bars - the receiver has
excluded the satellite (FDE).
